I’ve spent several hours Google-ing and trying to get libvirt to start without the following error:

I’ve followed several posts on setup:

Just a couple of the many troubleshooting articles I’ve tried:

Has anyone seen this one before and recall what you did to address it? Any thoughts, by chance?

Thanks!

Find out what is preventing libvirtd from starting. The systemctl status command just shows the last log entries, but not the error.

Use journalctl -u libvirtd.service to see all log messages.

Thanks for the reply @xabbu, that’s very helpful to finally be able to see the actual error now lol.

It was full of this following:

I’ll see what I can do with that…

P.s. I tried journalctl -xe but, it didn’t give me any more details; nice to know we can dig down a bit deeper with journalctl -u libvirtd.service

Okay, so far I think it’s working now:

❯ sudo systemctl status libvirtd

Jan 19 20:55:41 username systemd[1]: Started Virtualization daemon.

I found this:

libvirt_storage_backend_rbd.so links to both librbd.so.1 and librados.so.2 which both link to libceph-common.so.2 which links to libfmt.so.7
fmt is only listed in ceph-libs makedepends. Add fmt to depends of ceph-libs?

I installed fmt and it seem to start working right away and after a reboot too.

❯ sudo pacman -Syu fmt

Thanks again @xabbu :grin:
