Hello,
I'm not an expert, but did you follow this link?
https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool
Because for CentOS I see that the command name begins with centos and not redhat.
Also, the main error seems related to "not found" and indeed the mirrorlist path with "7.0" doesn't exist.
But it does exist instead the path with
http://updates.atomicorp.com/channels/mirrorlist/atomic/centos-7-x86_64
Perhaps a "yum clean all" and then follow the tips page could also resolve the repo mismatch problem.
For the hypervisor problem I think it depends on the fact that cpuinfo is that of the hypervisor itself and not a real problem. Just my opinion.
Hih,
Gianluca
