Issue description
processes freeze when accessing mounted device within LXC VM if limits.cpu set to 2-5
VM is still usable but mounted device can not be used, any process accessing it will freeze.
It does not matter if mounted folder originates from a xfs or a zfs filesystem, happens for both.
Workaround is to set limits.cpu to an integer eg. lxc config set <container-name> limits.cpu 4
The setting lxc config set <container-name> limits.cpu 2-5 works for containers, so this issue only appears when using it for VM's.
This happened while migrating from container to VM ( as some docker container frameworks like mailcow have issues and do not support LXC properly)
Steps to reproduce

create VM

lxc init ubuntu:focal test --vm
lxc config device add test backuparchive disk source=/archive/test path=/mnt/archive
lxc config set test limits.memory 8GB
lxc config set test limits.cpu 4
lxc config set test limits.cpu 2-5

enter VM lxc shell test
access mounted device

ls -lah /mnt/archive

That's unusual, can you show:

cat /proc/self/mountinfo in the vm
dmesg in the vm
ps fauxww on the host
dmesg on the host

That's unusual, can you show:

cat /proc/self/mountinfo in the vm
dmesg in the vm
ps fauxww on the host
dmesg on the host

This was reproduceable as described above, but now, for reasons unknown following happens:
lxc testvm being created and started, but lxc switching to STOPPED state, while qemu is still running, also it can't be stopped via lxc commands nor being deleted, only if qemo is manually killed.
Not sure what and why this behaviour changed to not working, i'm still investigating and yet unclear if this is related.
lxc init ubuntu:focal testvm --vm
lxc config set testvm limits.cpu 2-5
#lxc config device add testvm exttestvm disk source=/external/mount/backup path=/mnt/external
lxc start testvm

lxc ls (host)

Anything relevant in the log files at /var/snap/lxd/common/lxd/logs/testvm/ ?

here we go, got it working again.
I loaded aufs and overlay modules in order to get docker in an other container working, maybe that solved that one as well, even if that relation is unclear to me.
however, the issue is still reproducable, please find below the requested output:

Yeah, that's a bit confusing. Not sure what was causing the VM startup issue initially.
It's the first time I see qemu complain about 9p performance, though the option it refers in its help is a guest-side option so somewhat outside of our control. The virtiofsd process apparently panicing is likely the issue in your case as once that hits, it would immediately block all I/O to the virtiofs mount in the VM.
It suggests it's crashing because of a bad message received from within the VM though, so not too sure what's that about.
Can you identify a particular file or file operation which is triggering this? If so, that may be enough to file an upstream bug against qemu.

I'm not getting anything with strace, it just stopping
But how is that related to the cpu options?
In my previous tests it was not working with:
lxc config set testvm limits.cpu 2-5
but it was working with:
lxc config set testvm limits.cpu 2
btw. the start issue is back

How much free memory does that system have?
Other than checking the basics, it could really be anything from a qemu bug to a CPU/firmware problem on your system.
You're the first user reporting this of about 5k active users using LXD 4.10 with virtual machines (based on image download stats) so it seems like a very uncommon issue.

new more reproduceable examples.
installed some additional packages as qemu was complaining when triggering manually

apt install libspice-server1 libusbredirparser1 librbd1  solves this warning (might not be required for lxd)

from ops perspective, I'd suspect something related to limits.cpu
so if setting this via lxc config set testvm limits.cpu 2 the lxc-vm freezes or storage issue appears.
if the corresponding line in the config is being removed eg. via lxc config edit testvm or unset via lxc config unset testvm limits.cpu then both issues are gone and everything runs fine.
Workaround:
lxc config unset testvm limits.cpu -> vm boot up && storage driver works
mount in vm
lxd_exttestvm on /mnt/external type virtiofs (rw,relatime)

accessing mounted device in vm

what is the limits.cpu option doing ?
lxc config set testvm limits.cpu 4
qemu.conf:
# CPU
[smp-opts]
cpus = "4"
sockets = "1"
cores = "4"
threads = "1"

vs.
lxc config unset testvm limits.cpu
qemu.conf:
# CPU
[smp-opts]
cpus = "1"
sockets = "1"
cores = "1"
threads = "1"

diff between limits.cpu=4 (qemu.conf) and  unset limits.cpu (qemu.conf.1)

with limits.cpu set to a value, it does not reach following console output, it freezes before that

Don't try to run qemu directly the way you did, you'll get in trouble.
The snap contains all those libraries directly but you need it all mounted properly in a mount namespace.
What you're doing here is starting qemu with half the things coming from the snap and half the things from your system, likely in very different versions...
limits.cpu simply increases the number of vcpu and network queues in the VM, nothing special.
Most of my VMs have between 4 and 24 vCPU configured so that's not really a reproducer :)
Do you have any other physical system you could try this on?

I haven't startet it manually, just wanted to figure out if dependencies are missing, as explained by you this should be fine.
I'm using a regular HP DL360 G6 server, so nothing extra ordinary, maybe a bit old, but still common used hw.
however, I think I found something.
while error: can't find command hwmatch'.` catched my attention and I read about it on  here -> https://github.com/lxc/lxd/issues/7224, I thought it might be a kernel issue.
And it was, the -kvm kernel doesn't work properly, for some reasons, so whoever is maintaining that image that comes by default, might need to look into this in detail, test it properly and fix it -> any idea how/where  this can be addressed? ubuntu cloud team?
The issues do not appear when quickly spawn a vm with default values, so this might not have been poped up yet that often?

Permanent workaround to solve the 2 issues:

vm won't boot, freezes, lxd is in STOPPED , while qemu is still running and all related pids needs to be killed manually to even start or delete the vm
freeze while accessing mounted storage driver

Steps:
1.) do not configure more cpus / keep limit.cpu unset / do not mount storage driver
2.) onfisrt boot, in the vm, install generic kernel and remove the kvm kernel
apt install linux-generic
apt remove linux-image-5.4.0-1032-kvm
update-grub

3.)  when non-kvm kernel is running, all the options work as intended / set limit.cpu and mount storage driver
so my conclusion is also that it is not a LXD issue, but some ppl might end up here searching for a solution or workaround.
Maybe there is an option to document this and provide an alternative image without kvm kernel, so one can choose in case someone run into the same issue ?

Ah, can you try lxc launch images:ubuntu/20.04/cloud v1 instead?
If that behaves properly, then it may be worth filing a bug at https://launchpad.net/ubuntu/+source/linux-kvm/+filebug so someone on the Ubuntu kernel team can figure out what's up with the kvm kernel.

you mean lxc launch images:ubuntu/20.04/cloud v1 --vm right?
yep, this works fine so far and makes the workaround with manually switching kernel obsolete (as generic kernel is used by default) ;-)
lxc launch images:ubuntu/20.04/cloud v1 --vm
lxc config set v1 limits.cpu 4
lxc config device add v1 extv1 disk source=/external/mount/backup path=/mnt/external
lxc start v1
lxc console v1

however  if using limits.cpu 2-5 then it won't start, so this should be avoided.
lxc config set v1 limits.cpu 2-5

Confirmed here that there's something weird going on with limits.cpu and a specific pinning.
Will look into it some more as that sure used to work and I actually have a bunch of production systems using exactly that...

I've submitted a fix which appears to be working fine for me.
Apparently the issue is that in situations were pinning is used, a NUMA config is created which was then in some cases (when hugepages isn't used) would end up with the main memory definition using memfd (as was introduced with the switch to virtiofs) but the old ram backend for the NUMA definition.
Apparently that's causing some wonky memory setup which Linux then hangs on.

Sorry, this does not fix the issue on my end, can you please reopen the issue?
Steps:
lxc init images:ubuntu/20.04/cloud v1 --vm
lxc config set v1 limits.cpu 2-5
lxc config device add v1 extv1 disk source=/external/mount/backup path=/mnt/external
lxc start v1
lxc console v1

Still not working with imits.cpu 2-5

Hmm, can you show the qemu.conf you're getting?

You're apparently hitting kernel resource issues eventually leading to qemu dying now, so that's quite a bit different.

Based on that config, you're not using a fixed LXD

Oh, I forgot something in my instructions, you need a 'chmod 755 /var/snap/lxd/common/lxd.debug' before the reload

sorry, I've overlooked that as well, thought there would be some magic fixing this on first startup.
however, looks good now, at least with the cloud image (not yet tested with the linux-kvm) :
lxd.debug is now running:
2850605 ?        Ss     0:00 /bin/sh /snap/lxd/19164/commands/daemon.start
2850741 ?        Sl     0:05  \_ /var/snap/lxd/common/lxd.debug --logfile /var/snap/lxd/common/lxd/logs/lxd.log --group lxd

lxc init images:ubuntu/20.04/cloud v1 --vm
lxc config set v1 limits.cpu 2-5
lxc config device add v1 extv1 disk source=/external/mount/backup path=/mnt/external
lxc start v1
lxc shell v1

it boots up properly and I can access now /mnt/external without hangs/freezes
