What is your call?
Comment 6 Paolo Bonzini 2013-12-02 11:15:03 EST
Not a bug.
Comment 7 Ronen Hod 2013-12-02 12:12:56 EST
Paolo, How comes?
It should be fixable.
Are you saying that it is not needed? Could be, but it doesn't look good.
Can it happen to an innocent Libvirt user?
Comment 8 Paolo Bonzini 2013-12-03 04:52:43 EST
More precisely, not a bug as far as we are concerned.  We do not support TCG except for the very specific case of running libguestfs, I think?

It is fixable, but I have no idea whether it is easy or hard because I have no experience.

It can happen if you use 'qemu' instead of 'kvm' as the virtualization technology.  Perhaps we should add a "taint" flag to libvirt for domains that are not running under KVM and have qemu-kvm in the emulator name.
