That seems to have worked! Although what's weird is that it only shows the one VM and all of this started when I created another VM and then downloaded the new VirtIO. Is there anything I could have done to have caused this or anything I can do to prevent this? I do need to either build or import that existing VM again. Quote Link to comment

Difficult to guess what happened, would need diags from that time, but make sure you always have an up do date backup of libvirt.img Quote Link to comment
MyNameIsMark Posted September 10, 2020 Share Posted September 10, 2020 Had the same problem "Libvirt Service failed to start". Just forgot to format the VM disc. After formatting, VM Manager loaded. Quote Link to comment
DaSlinky Posted March 18, 2021 Share Posted March 18, 2021 This just started for me this morning. None of my vms will boot so I cycled the vm service and got this error message. seeing this recurring statement in logs, also attached system diag. tower-diagnostics-20210318-0723.zip Quote Link to comment
JorgeB Posted March 18, 2021 Share Posted March 18, 2021 loop2 is the docker image, and it's corrupt so it needs to be recreated, because of the log spam can't see the problem with libvirt, but most likely it's because cache is completely full, free up some space, reboot to clear the logs and if still issues post new diags.

A reboot resolved the docket error. Lost all my VMware sessions but the images are still there at least. When I got off create a new image it threw the screenshot below. After I cycled the vm manager it tossed the liberty message. tower-diagnostics-20210318-0740.zip Quote Link to comment

biggiesize Posted July 26, 2021 Share Posted July 26, 2021 Last week I had this issue. I ended up having to recreate libvirt.img. Now I'm having the same issue again a week later. Any idea what would cause this to repeat itself? Logs are attached and any help is greatly appreciated. fortknox-diagnostics-20210725-2244.zip Quote Link to comment

kysdaddy Posted March 8, 2022 Share Posted March 8, 2022 Hello, I just lost my VM with a Libvirt Service failed to start. error. I am a complete noob at VM, I have been running Homeassistant as a docker for years, moved to the VM HA OS about 2 months ago, loved it. Last night it died, I am sure that it wasn't a natural death, that I did something stupid and killed it accidently. I am posting my diagnostic. BTW I just tried to restore my VM from a backup but neglected to write down the format of the name, that was done after the Libvirt Service failed to start. so it is not the cause. However if the format is not accurate please feel free to correct my stupidity. Than you Chas tower-diagnostics-20220308-0730.zip Quote Link to comment

kysdaddy Posted March 8, 2022 Share Posted March 8, 2022 I'm remote, I told the system to reboot, and checked back later, perhaps it failed to do so. Trying again. I guess that it didn't reboot the first time, it is back and working, the VM was named right as my Homeassistant is working too. Thank you for your help. Chas Quote Link to comment

jbuszkie Posted June 22, 2023 Share Posted June 22, 2023 I'm getting this message any time I stop and start the VM manager. With a reboot It starts fine. But if I disable VM's and then enable VM's, libvirt doesn't start and there is nothing in the /var/log/libvirt/libvirtd.log file. Where can I look to debug this? This all started when I started playing with "Virtual Machine Wake On Lan" I'm trying (unsuccessfully) to start a VM with WOL. Now I have no idea if this is connected. I don't remember the last time I had to disable/enable the VM's And I would like to get the WOL for VM's working.. But that's a separate thread! lol Jim Quote Link to comment
stefan.tomko Posted August 29, 2023 Share Posted August 29, 2023 Hello. I have had few occasions where libvirt.img got corrupted. Usually when power went out and Unraid did not manage to shut down cleanly. Last night I had power outage, this time it looks like it shut down cleanly. However I faced this issue again. Attached is my diagnoatics, appreciate if someone could advise what is going on. tower-zohor-diagnostics-20230829-1121.zip Quote Link to comment
terafil Posted January 12 Share Posted January 12 (edited) Hello folks, I have a similar problem: after a power outage my VM does not appear, it is turned on, but not working completely. Network and USB devices do not work. If I disable and re-enable the VMs, I get "Libvirt Service failed to start.". I tried rebooting the system, deleting libvirt.img and recreating the VM but I still have the same problem. I don't have any logs on logterminal/libvirt. What can I do? I attach the diagnostic file Thanks in advance Terafil microserver-diagnostics-20240112-1057.zip Edited January 12 by terafil Adding screenshots Quote Link to comment
