Hello,

I had an unclean shutdown (power cut and powered back up itself) for some reason when passing a gpu to a vm. Since then, I have not been able to start libvirt. Diag attached. My /etc/libvirt/ dir seems to have been automatically renamed to /etc/libvirt-/. What does a dash at the end of a directory signify? Can I just do the following?

mv /etc/libvirt-/ /etc/libvirt/

Noteworthy errors:

syslog 

root: /usr/sbin/libvirtd: error: Unable to initialize network sockets. Check /var/log/messages or run without --daemon for more info.

 

libvirt

17277: error : virNetSocketNewListenUNIX:511 : Failed to bind socket to '/var/run/libvirt/libvirt-sock': Address already in use

 

BTW, deleting libvirt img did not fix the issue.

 

Thanks in advance,

Kevin

included unraid version in title as required

TL;DR

Files ending in a dash seem to indicate some sort of corruption.

 

Long version:

Found the solution. I think I should share it as it may help others.

Apparently my setup cuts power and resets when I passthrough one of my GPUs - specifically the Nvidida Quadro K600. Knowing that I had an unclean shutdown, I went down the thought processes of data corruption. Which made me remember, a while back I noticed on a corrupted copy unraid usb, the dash ending files (syslinux-) appeared there too.

 

So, I ran the following and pressed option 2 to restore from backup.
 

fsck /boot

 

At this point I restarted and was able to start libvirt.

 

Now time to figure why my K600 is causing reset.

I just had this happen but your solution didn't seem to work. 

 

My /etc/libvirt is empty but /etc/libvirt- has contents. 

 

Should I copy libvirt- over libvirt, run the fsck, and then reboot?

 

This is driving me insane as it’s my work VM 😞

If you have a backup of your USB. Try and restore from there. Looks like unclean shutdowns are the cause of corrupting files.
