[libvirt-users] libvirt 1.2.10 and latest EL6 qemu-kvm

[Franky Van Liedekerke]

(I'm sorry, I didn't find my original message but I provide the
archive link: https://www.redhat.com/archives/libvirt-users/2015-January/msg00069.html
)

I just tried the latest libvirt release (1.2.12), combined with the
following qemu EL6 package from centos:
qemu-kvm-0.12.1.2-2.448.el6_6.x86_64

Using 1.2.12 and this version of qemu-kvm, I still get the following
error when trying to start a domain:

error: Failed to start domain btcab0001ap.unix.banksys.be
error: internal error: unable to execute QEMU command 'qom-list': The
command qom-list has not been found

The older qemu package (qemu-kvm-0.12.1.2-2.415.el6_5.14.x86_64) works
just fine though (I also tried the qemu-rhev-packages for el6 from
ovirt, but no change).
I verified the changelog from libvirt 1.2.12 and the earlier suggested
fix is in there (but doesn't seem to change anything):

        qemu_monitor: introduce new function to get QOM path


Now, I have activated libvirtd debug and these are the qom-list lines
(I can provide the full logfile if wanted):

(again: full log can be provided, but maybe that should be sent in
private, I don't know if it is allowed as an attachment here).

Any tips?
