HI!
After the last OS update (openSUSE Tumbleweed) with libvirt being updated from 3.0.0 to 3.1.0 starting the VMs (qemu-kvm) does not work anymore:
error: internal error: child reported: Kernel does not provide mount namespace: Permission denied
Hey, this is definitely a libvirt bug. Since 3.1.0 libvirt spawns each qemu in its own mount namespace so that it can have private /dev mount. I've heard that there are some issues with AppArmor - is that what are you using?
Hmm, yes. I was using AppArmor. Disabling it helped. I will point the author of the AppArmor profiles in this direction.
Meanwhile, you can disable namespaces by setting:
namespaces=[]
in qemu.conf.
Only setting this did not help. Ciao, Michael.
