[one-users] Error Migration

[Javier Fontan]

It seems you have some hosts with RHEL 6.4 and others with a different
version, possibly 6.5. RHEL/CentOS has defined on machine type per OS
version. This is done as the qemu/libvirt are not exactly the same
between releases and could be incompatibibilities. When the machine
type is not specified the default one is the one matching the version
of the node where the VM was started.

In your case it seems the host is 6.5 so it got the machine type
rhel6.5.0. In version 6.4 this machine type does not exist, as you can
see in the list of the log file.

One way to solve this problem in the future is to set the machine type
to rhel6.4.0 as it is supported in both 6.4 and 6.5. Since one 4.6
this is supported section both in the VM definition or the defaults
for the KVM driver in the OS section [1]. In the defaults fide for the
driver (vmm_exec_kvm.conf) something like this will do:

OS = [ boot = "hd", arch = "x86_64", MACHINE = "rhel6.4.0" ]

This won't fix your already started VMs.

Cheers
