Centos 6.6 on Centos 6.6,internal error process exited

Centos 6.6 on Centos 6.6,internal error process exited

[mad Engineer]

I have a server with centos 6.5 installed and later upgraded to 6.6
after restart, installed kvm and created centos 6.5 as guest and later
upgraded guest to 6.6.
Now after host reboot i am not able to start guest as it shows


"Internal error process exited while reading console log output
Supported machines are:
pc                   RHEL 6.5 pc
RHEL 6.5.0      RHEL 6.5 pc
RHEL 6.4.0      RHEL 6.4 pc "


Even though by changing "Machine" in xml config from RHEL 6.6.0  to
RHEL 6.5.0 vm has started and its working.

But why is 6.6 guest not supported in 6.6 host,i suspect its because
of some upgradation issue from 6.5 to 6.6.Can some one please help me
understand this.


Thanks

rhel6.6.0 is not a guest OS version, but a machine type ("motherboard
version" so to speak) provided by the host.  If you do not have a
rhel6.6.0 machine type in your CentOS 6.6 host, something has gone wrong
in the upgrade.

That said, you can use the rhel6.5.0 machine type just fine.  The
differences are minimal.
