CentOS - Dec 2018 - qemu-kvm-common-ev-2.12.0-18.el7_6.1.1.x86_64 - lost KVM guests - qemu-kvm-ev

hi guys,

I updated to qemu-kvm-common-ev-2.12.0-18.el7_6.1.1.x86_64 (also 
libvirt) and my Centos 6.10 kvm guests now do not start.

Funnily enough Win10 guest are fine, only Centoses cannot start, 
silently & without any errors.

Any care to comment?

many thanks, L.

It looks like you installed CentOS 7 packages on a CentOS 6 system.
I'm amazed it even worked.  Try removing the packages and
re-installing the appropriate packages for CentOS 6.

Oh, never mind me, I missed that you were saying that your *GUESTS*
don't start.

Did you do a full update to CentOS 7.6.1810, or just the libvirt/qemu packages?
