NetBSD VM on bhyve (on TrueNAS)

My new NAS at home is running TrueNAS Core. So far, it has been excellent, however I struggled a bit setting up a NetBSD VM on it. Part of the problem is that a lot of the docs and how-tos I found are stale, and the information in it no longer applies.

TrueNAS Core allows running VMs using bhyve, which is FreeBSD’s hypervisor. NetBSD is not an officially supported OS, at least according to the guest OS chooser in the TrueNAS web UI :) But since the release of NetBSD 9 a while ago, things have become far simpler than they used to be – with one caveat (see below).

UEFI Boot

NetBSD 9 and newer fully support booting through UEFI. This simplifies things because (as far as I understand) bhyve does not really support BIOS boot, it prefers loading the kernel directly.

It used to be the case that it was hard to get the installer working, so people started with an image of an already installed system, plus GRUB for bhyve. This is all very clunky and, to be clear, it is no longer needed.

Starting the Installer

Begin by downloading a CD image for the installer – the regular NetBSD 9_STABLE/amd64 installation CD image from https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/amd64/installation/cdrom/ – and storing it on the ZFS volume.

In the web UI, under “Virtual Machines”, create a new one with the following settings:

  • Guest OS: FreeBSD
  • Boot method: UEFI
  • VNC: enabled
  • “wait with boot until VNC connects”: enabled
  • Use VirtIO for disks and network
  • When asked for an install CD, select the CD image downloaded earlier

Fallout

When you boot now, you will find that VNC disconnects after about five seconds. Further investigation shows that it’s actually the bhyve hypervisor that exits with a segfault.

This turns out to be an issue with the USB 3 (xhci) driver in the NetBSD kernel – or rather, it is probably a bhyve bug but disabling the xhci driver on the guest side works around it. Disabling xhci is not a big deal because the VM does not need native USB 3 anyway.

To work around:

  1. Start the VM, then connect to VNC.
  2. Once the bootloader appears, press (3) to go to the prompt. Enter boot -c.
  3. In the userconf shell, enter disable xhci*, then quit.
  4. The installer should appear, letting you install normally.
  5. After installation, shut down the VM and remove the CD from the list of devices.
  6. Start it again and repeat steps 2 and 3 to boot into the installed system.

To make the workaround permanent, edit the file /boot.cfg so that the first line reads

menu=Boot normally:rndseed /var/db/entropy-file;userconf disable xhci*;boot

At this point, you should also uncheck the “wait for boot until VNC connects” checkbox in the settings so the VM can start unattended in the future.

Success!

Here is the obligatory dmesg output for this system:

Using CPU Subsets for Building Software

Like many ARM CPUs, the one in the Pinebook Pro has a “big.LITTLE” architecture, where some cores are more powerful than others:

[     1.000000] cpu0 at cpus0: Arm Cortex-A53 r0p4 (v8-A), id 0x0
[     1.000000] cpu1 at cpus0: Arm Cortex-A53 r0p4 (v8-A), id 0x1
[     1.000000] cpu2 at cpus0: Arm Cortex-A53 r0p4 (v8-A), id 0x2
[     1.000000] cpu3 at cpus0: Arm Cortex-A53 r0p4 (v8-A), id 0x3
[     1.000000] cpu4 at cpus0: Arm Cortex-A72 r0p2 (v8-A), id 0x100
[     1.000000] cpu5 at cpus0: Arm Cortex-A72 r0p2 (v8-A), id 0x101

The A72 is a more powerful than the efficiency-oriented A53, it has out-of-order execution, plus it reaches a higher maximum clock rate (1.4 GHz for the A53 and 2.0 GHz for the A72 in the Pinebook Pro).

On NetBSD-current, the kernel scheduler prefers the big cores to the little ones. However, when building software, you may want to force the build process onto the big cores only. One advantage is that you still have the little cores to deal with user input and such, yet your build has the highest performance. Also, building with all cores at the highest clock rate will quickly lead to overheating.

NetBSD has a somewhat obscure tool named psrset that allows creating “sets” of cores and running tasks on one of those sets. Let’s try it:

$ psrset
system processor set 0: processor(s) 0 1 2 3 4 5

Now let’s create a set that comprises cpu4 and cpu5. You will have to do that as root for obvious reasons:

# psrset -c 4 5
1
# psrset
system processor set 0: processor(s) 0 1 2 3
user processor set 1: processor(s) 4 5

The first invocation printed “1”, which is the ID of our new processor set. Now we can run something on this set. Everything run below only sees two cores, cpu4 and cpu5. Note the “1” in the command below. This is the ID from before.

# psrset -e 1 make package-install MAKE_JOBS=2

If you run htop or similar while your package is building, you will see that only cpu4 and cpu5 are busy. If you have installed estd to automatically adjust CPU clocks, you will notice that cpu4 and cpu5 are at 2 GHz while the four little cores are running at a cool 400 MHz.

Getting Started with NetBSD on the Pinebook Pro

If you buy a Pinebook Pro now, it comes with Manjaro Linux on the internal eMMC storage. Let’s install NetBSD instead!

The easiest way to get started is to buy a decent micro-SD card (what sort of markings it should have is a science of its own, by the way) and install NetBSD on that. On a warm boot (i.e. when rebooting a running system), the micro-SD card has priority compared to the eMMC, so the system will boot from there.

As for which version to run, there is a conundrum:

  • There are binary packages but only for NetBSD-9. On -current, you have to compile everything yourself, which takes a long time.
  • Hardware support is better in NetBSD-current.

The solution is to run a userland from NetBSD-9 with a NetBSD-current kernel.

As the Pinebook Pro is a fully 64-bit capable machine, we are going to run the evbarm-aarch64 NetBSD port on it. Head over to https://armbsd.org/arm/ (thanks, Jared McNeill!) and grab a NetBSD 9 image for the Pinebook Pro. Then (assuming you are under Linux), extract it onto the memory card with the following command:

zcat netbsd-9.img.gz | dd of=/dev/mmcblk2 bs=1m status=progress

Be sure to check that mmcblk2 is the correct device, e.g. by examining dmesg output! Once the command is done, you can reboot. Once booting is finished, you can log in as root with no password. The first thing you should do is to set one, using passwd.

To the eMMC!

Would you like to replace the pre-installed Manjaro Linux on the eMMC?

It makes sense to have your main OS on the built-in storage, since it is quite a bit faster than the typical micro-SD card. In my tests, I get write speeds of about 70 MiB per second on the eMMC.

By the way, if you want more and even faster Storage, PINE64 will sell you an adapter board for adding an NVMe drive (a fast SSD).

Once you have booted NetBSD from the memory card, mount the Linux volume and copy over the image file from before, then unmount and extract it in exactly the same way as above. The only difference is that the target device is called /dev/rld0. Shut down the system, remove the memory card, switch it back on and watch NetBSD come up :)

Getting a -current Kernel

To have better driver support, I recommend installing a NetBSD-current kernel. To do that, you just need to replace the /netbsd file with the new kernel – no changes to the bootloader are required.

You can find a pre-built kernel under https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/evbarm-aarch64/binary/kernel. Download the file and install it:

cp /netbsd /netbsd.old
gunzip netbsd-GENERIC64.gz
install -o root -g wheel -m 555 netbsd-GENERIC64 /netbsd

You will find that there is now a driver for the built-in Broadcom Wi-Fi (as the bwfm0 interface) but the firmware is missing. To fix this, download the base.tgz set from the same location and extract the firmware blobs only (as root):

cd /
tar xvpfz /path/to/base.tgz libdata/firmware

In my experience however, the Broadcom Wi-Fi driver is extremely likely to make the system crash or hang. I tend to rely mostly on an old Apple Ethernet-USB adapter (an axe interface).

NOTE: I have since back-pedaled and returned to NetBSD 9. Other than the unstable Wi-Fi, I also had crashes when running npm install and other issues.

Update 2022-08-27: changed the device name for writing the image, thanks Nikita!

Pinebook Pro, First Impressions

Note: This post was written on the Pinebook Pro :)

After seeing it in action at FOSDEM (from afar, as the crowd was too large), I decided to buy a Pinebook Pro for personal use. From the beginning, the intention was to use it for pkgsrc development, with NetBSD as the main OS. It was finally delivered on Thursday, one day earlier than promised, so I thought I would write down my first impressions.

If you have never heard of the Pinebook Pro: It is a cheap, open, hackable laptop with an ARM processor, the successor of the original Pinebook (which I thought was too low-end to be a useful daily driver) with generally more premium components.

As I alluded to in the first paragraph, the enthusiasm of the Free Software community is incredibly strong! Nothing showed this better than the incredible resonance from a tweet with a quick snapshot after the first boot:

You’ll note, in passing, that on the photo, I am downloading the NetBSD install image :)

What makes this device attractive, apart from the price, is the ARM architecture without the baggage of the PC world. What’s more, an open and hackable system in the age of Macbooks with soldered everything, tablets that you cannot open, “secure” boot that severely limits what you can run on it, is something of a counterculture device. The Pine64 folks have built a great community that embodies the true hacker spirit.

The Hardware

Here is where I am going to be harsh: in some ways, using this device feels like a regression.

I was previously using a Samsung Chromebook Pro, a Pixelbook and a Pixel Slate as laptops. Compared to these, the Pinebook Pro has

  • no HiDPI screen,
  • no touchscreen,
  • a barrel connector power supply,

and peripherals are mostly using USB-A port. To be fair, there is USB-C, and it can be used to charge the machine, so I haven’t used the original charger yet.

The display resolution is 1920x1080, equivalent to about 100 dpi. While I regret the absence of HiDPI, it is well lit and well readable. The viewing angles are fairly large, and the colors are crisp. The default Manjaro Linux wallpaper is a great showcase for this.

The Pinebook Pro is vaguely shaped like a MacBook Air from a few years ago, with the same curved bottom. At 14", it is surprisingly large – the machines mentioned above are 12 to 13". Compared to the MacBook and Pixelbook in their quest for ever thinner devices, the Pinebook Pro feels strangely empty. I guess there is actually free space on the inside that you can use for upgrades and such.

The most similar laptop I have used is the HP Chromebook 14. Against this, the Pinebook Pro holds up really well though: it is lighter, has a better keyboard and display and is actually cheaper!

Keyboard and Trackpad

The keyboard is an absolute joy to use. Really, it’s great. The keys have a large amount of travel, comparable to older MacBook Pros, before they introduced the terrible keyboard. The layout (I have ANSI, i.e. US) is exactly what you would expect. This is definitely made for typing a lot.

On the other hand, I am not friends with that trackpad. I am hoping I can get used to it at some point. The way it tracks small finger movement is … weird and counter-intuitive, and I am having a hard time hitting small click targets. It has two mouse buttons under the bottom left and bottom right, so clicking in the middle usually has no effect. For dragging, you need to keep one finger in the corner on the button and move another finger, which sometimes triggers multi-touch gestures.

Battery life

I have not done detailed measurements, but it seems pretty good at about 7 hours. Here is the envstat output while writing this:

                               Current  CritMax  WarnMax  WarnMin  CritMin  Unit

            battery voltage:     3.935                                         V
            battery percent:        79                                      none
  battery remaining minutes:       319        0        0        0        0  none

                        CPU:    42.778   95.000   75.000                    degC
                        GPU:    43.333   95.000   75.000                    degC

Performance

Compared to all those ARM SBCs I have used (Raspberry Pi, Orange Pi, Pine-A64), the Pinebook Pro feels really fast. Storage (at this point I am using a memory card) is decent speed-wise, and compilations are reasonably fast – though my five year old Intel NUC with an i7 still beats it by far, of course. But my workload involves compiling lots of stuff, so this seems like a good fit.

Graphics performance has not blown me away. Animations on Manjaro stutter a bit, Midori on NetBSD (the first browser that I tried) is really testing my patience.

Hackability?

I noticed that opening the bottom of the housing is screwed on with standard Philips head screws and easy to open. There are no rubber feet glued on top of the screws, no special tools needed.

You can easily boot your custom OS from the micro-SD card reader. As mentioned, I bought this machine for running NetBSD on it, which works well.

There are upgrade kits available, for example an adapter to add an NVMe disk instead of the eMMC. For the original Pinebook, there has been an upgrade kit with a better processor even.

Because we are on ARM, there is no “Intel Inside”, and consequently, there are also no stickers, except for one on the underside that gives the model number.

Conclusion

This has become longer than I intended. Despite my criticism, I really like this machine. I am hoping I can get some good development work done with it and use NetBSD for my daily computing tasks.

Stay tuned for another post with some NetBSD tips!

Pkgsrc Buildbots

After talking to Sijmen Mulder on IRC (thanks, TGV Wi-Fi!), I began thinking more about how you could automate the pkgsrc release engineers away.

The basic idea for a buildbot would be this:

  1. Download and unpack latest pkgsrc.tar.gz for the stable branch.
  2. Run the pullup script with the ticket number, then run whatever pullup script it outputs.
  3. Figure out the package that this concerns (perhaps from filenames).
  4. Go to the package in question, install its dependencies from binary packages.
  5. Build (make package is probably enough, or perhaps also install?).
  6. Upload build log to Cloud Storage.
  7. Post an email to the pullup thread with status and a link to the log.

For extra points, do this in a fresh, ephemeral VM, triggered by an incoming mail.

You would also need a buildbot supervisor that receives mails (to know that it should build something) and that launches the VM. I know that Google App Engine could do it, as it can receive emails. But maybe Cloud Functions would be the way to go?

In any case, this would be a cool project for someone, maybe myself :)

Issues with Pull-up Ticket Tracking

This project is largely orthogonal to improvements in the pullup script. Right now, there are a number of issues with it that make it require manual intervention in many cases:

  • The tracker (req) doesn’t do MIME, so sometimes mails are encoded with base64 or quoted-printale. This breaks parsing the commit mails.
  • Sometimes, submitters of tickets insert mail-index.netbsd.org URLs instead of copies of the message.
  • Some pullup tickets include a patch instead of, or in addition to, a list of commits. For instance, this may happen when backporting a fix to an older release instead of pulling up a bigger update.
  • Sometimes, commit messages are truncated, or there are merge conflicts. This mostly happens when there has been a revbump before the change that is to be committed – in the majority of cases, the merge conflicts only concern PKGREVISION lines.

I am wondering how much we could gain, e.g. in terms of MIME support, from changing the request tracking software. admins@ uses RT, which has more features. Perhaps that could be brought to pullup tickets?

Leaving AWS

Today, I deleted my Amazon AWS account.

And done!

I had been on AWS since about 2011. My usage was mainly for two things:

  1. Saving large amounts of files (build logs and such) on S3;
  2. Running NetBSD VMs on EC2.

EC2 is based on Xen, and NetBSD runs really well in PV (paravirtualized) mode on Xen. However, XSA-240 means that a malicious PV guest may crash (or even otherwise exploit) the hypervisor, with the recommended fix being to not run untrusted PV guests. Over night, Amazon disabled PV, making NetBSD VMs useless.

In general, EC2 has been moving away from Xen. The newer instance types already no longer supported PV; there are two higher-performance paravirtualized modes (PVH and PVHVM) that are preferred these days, and that NetBSD does not support. The newest machine types use a custom hypervisor based on KVM.

The way the PV change was rolled out highlighted another long-standing EC2 problem: instances would continue running until the server they ran on got rebooted, at which point they were migrated to a random machine. If the target machine had PV disabled, the VM simply did not come up again. I have had the same type of issue in the past, where your VM randomly landed on a “good” or a “bad” machine and did not come up on the bad one. There is no way (AFAIK) to constrain to a certain subset of servers, e.g. running a certain hypervisor version.

Also, of course, there was no warning or announcement, just that VMs stopped working all of a sudden. A bunch of people were completely caught by surprise when their service became unavailable. I hope you have monitoring!?

The Alternative

Which brings me to where I did take my workloads: Google Cloud Platform.

(This has nothing to do whatsoever with who my employer is. I pay for my GCP usage with my own money.)

These days, NetBSD (8+) runs great on Google Compute Engine. There is a script (that I created) to stage instances at https://github.com/google/netbsd-gce, though there are no official NetBSD images around. My S3 usage works equally well using Google Cloud Storage. And I have always been a fan of App Engine, particularly because of its great Go support. https://bulktracker.appspot.com/ runs on App Engine.

Conclusion

My general impression is: Features are roughly on par, prices on GCP are a bit cheaper, and the Google Cloud SDK and command-line tools are better. So rather than let old, unusable VM images continue to rot and pay Amazon 2$ a month for that bit of storage, I let go of that AWS account. Bye, Amazon.

blog @ TNF

So now I am even posting over at TNF on http://blog.NetBSD.org/. Julian Fagir made new NetBSD flyers, and I committed them to the TNF website.

I know that I should write more here but there is not much new on the MirBSD front.

I updated the showcase to NetBSD-6_BETA on the Dom0, and now X refuses to start. Oh well. X does start when using a GENERIC kernel. This is very bad for showcase use, of course :(. pkgsrc is going into freeze very soon, and I did not do a whole lot of MirBSD fixes this time around. This is due to illness, searching for a new job, and working on the Go programming language, which is expected to hit version 1.0 Real Soon Now(TM).

I brushed up my Algorithms and Data Structures a bit by reading the third volume of TAOCP. Fantastic book.
