Can not launch LXD vm on vmware fusion host machine

LXD
1

I install Ubuntu 22.04 server on VMware fusion (mac), and when I run kvm-ok on the ubuntu vm everything seemed good:

INFO: /dev/kvm exists
KVM acceleration can be used

But, when I want to create a VM:

lxc launch images:ubuntu/22.04 vm1 --vm

I get this error:

Error: Failed to run: forklimits limit=memlock:unlimited:unlimited fd=3 -- /snap/lxd/23541/bin/qemu-system-x86_64 -S -name vm1 -uuid 4912d38d-9bff-407d-b915-a5336dcc9fcc -daemonize -cpu host,hv_passthrough -nographic -serial chardev:console -nodefaults -no-user-config -sandbox on,obsolete=deny,elevateprivileges=allow,spawn=allow,resourcecontrol=deny -readconfig /var/snap/lxd/common/lxd/logs/vm1/qemu.conf -spice unix=on,disable-ticketing=on,addr=/var/snap/lxd/common/lxd/logs/vm1/qemu.spice -pidfile /var/snap/lxd/common/lxd/logs/vm1/qemu.pid -D /var/snap/lxd/common/lxd/logs/vm1/qemu.log -smbios type=2,manufacturer=Canonical Ltd.,product=LXD -runas lxd: : Process exited with non-zero value 1

This is the result of the log:

Thats a QEMU crash.

Searching for that error lead me here:

Does that help?

+1. I do have the same issue here.
Host on Openssue15.4.
Old vms does not seem to start anymore after upgrade.

lxc start ubuntuClient

@cyphar Hey Aleksa, can you check on this please?
Running on opensuse 5.14.21-150400.24.41-default
lxd --version 5.9
from virtualization:containers reository.
@tomp Is ther anything you sould suggest in order to solve this?

5

New vms deos not work as well.

lxc launch ubuntu:22.04 ubuntu2 --vm
Creating ubuntu2
Error: Failed instance creation: Failed creating instance record: Instance type "virtual-machine" is not supported on this server: QEMU failed to run feature checks
6

Take a look at /var/snap/lxd/common/lxd/logs/lxd.log and near the top you should see some additional info near the lines “Instance type operational” (for containers), about why VMs are not operational.

7

Also LXD 5.10 had some improvements to the way we detect QEMU features, so you may find that works better.

8

I am on opensuse, not using snap.

9

Given that I am on opensuse, Will installing lxd from snap take into effect my current data store and installed vms/containers, and will it use my already created bridges?

10

Unlikely I would say. On ubuntu there is a migration path from deb to snap, but I don’t think the same thing exists/works for OpenSuse

11

Just had a look into using snap from deb, And if I could make it work with OpenSuse. That would definetly break my server setup.
@cyphar I wonder if could help. Is ther a timeline when we could have 5.10 on OpenSsue 15.4? It is really needed.

Hey @tomp I built from source.
but am getting this issue now

lxc start ubuntu
Error: lstat /usr/share/OVMF: no such file or directory
Try `lxc info --show-log ubuntu` for more info

had a look on Cannot start virtual machines missing OVMF Gentoo

Any idea please?

Hello @tomp ,
I am revisiting this as it did raise as an issue with my other server.

Running fresh opensue 15.4 lxd 5.10

// /var/log/lxd/lxd.log
level=warning msg="Unable to use virtio-fs for config drive, using 9p as a fallback" err="Virtiofsd missing" instance=u22 instanceType=virtual-machine

Does the enw logs help perhaps missing driver?

All good now. Thank you.
