Quote the essential part of the bug:
"This is some apparmor issue.
The qemu is not able to access /var/lib/libvirt directory when run as qemu:qemu.
I changed the user to root:root, the things are working fine now."
Note: The default is libvirt-qemu:kvm which works just fine.
Not sure where/why set qemu:qemu user/group for qemu.
But if I do set so in /etc/libvirt/qemu.conf and create such a user (qemu:qemu
is no default as I said).
With that set still the referred domcapabilities commands work.
If with qemu/qemu I try to start a guest it fails:
qemu-system-ppc64: failed to initialize KVM: Permission denied
As we have:
crw-rw---- 1 root kvm 10, 232 Feb 20 11:42 /dev/kvm
The attached ./sos_commands/kernel/dmesg has no apparmor Denies.
I have to set this to incomplete for now and need to ask:
- why user qemu:qemu?
- if you set non default users you might need to change a lot to get it
working.
- I read apparmor issues, but found none in the logs, could you provide the
messages of the apparmor denies
- the sosreport holds a lot, but just not e.g. the qemu.conf to set the user
TL;DR - I need to see the actual failing config and the error/Denial by apparmor
** Changed in: libvirt (Ubuntu)
Status: New => Incomplete
