CentOS 7.0 and CentOS 6.5? Why so old? I'm rather surprised that it only
freezes every few days... KVM/QEMU was in early stages for RHEL/CentOS 5
and 6. I think you at least go to CentOS 6.10 for the host, but even this
seems terribly old as a software baseline to use for a production server...

In any case, not a CentOS developers discussion... more a question for
somebody who still supports these old versions. Even Red Hat has declared
6.5 end of extended update support some time ago...
