[Serge Hallyn (serge-hallyn)]

That is very odd. Unless /etc is a read-only filesystemd I don't see why root would be denied permission to write to that file, and there are no apparmor denials in the kernel log. Could you please attach the files

/etc/apt/sources.list
/etc/apt/sources.list.d/*
/var/log/apt/history.log
/var/log/apt/term.log

and show the result of

ls -l /etc/libvirt
cat /proc/self/mountinfo

Odd, the qemu.conf error in the bug description does not show up in
the term.log.

What does

sudo systemctl status libvirt-bin.service

show?

What do you get when you do:

sudo ls -l /etc/libvirt/qemu.conf
sudo getfacl /etc/libvirt/qemu.conf
sudo libvirtd

and please attach the file 'libvirtd.out' after doing:

sudo strace -f -olibvirtd.out libvirtd

[Mustafa Muhammad (mustafa.muhammad)]

Now I am on new installation and this issue doesn't happen anymore.
You can mark it as closed as I can't reproduce it anymore.

[Serge Hallyn (serge-hallyn)]

Thanks for the update.

[Serge Hallyn (serge-hallyn)]

(marking 'invalid' meaning 'cannot reproduce any more')
