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... -- Mark Mielke <mark.mielke at gmail.com> -------------- next part -------------- An HTML attachment was scrubbed...
