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

Any care to comment?

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?

yes, I see my sentence was not complete, although it non-explicitly said 
Centos 7 (qemu package version).


So, host is Centos 7 updated to the latest (no fasttrack repo, but 
cr(rolling) yes) and quests are(if not gone now?)  Centos 6.10.


virsh start such a guest okey, complains of nothing, no errors but guess 
does not boot. I see qemu BIOS and boot menu but when it comes to 
booting the OS/grub/kernel, then this does not happen.


Checking qcow image with qemu confirms images are free of errors, etc. I 
can mount these Centos guests okey, filesystem seems good.


I do not want to downgrade just yet, but will have to check that option 
soon.
