I want to know about this problem concept. I know about psql command. We need a stable machine type to ensure migration, you can have different qemu-kvm versions on different hosts but as long as they support the same stable machine type they will have compatibility for migration. The setting which you set in database (but see patch below to make it a config option) allows you to specify the required machine type. Fedora uses machine types like pc-0.15 pc-0.14 pc-1.0 where as RHEL users different machine types.

I configured anything correctly. I defined ISO Domain and Data Domain for iso file and virtual machine file under NFS storage. I made new virtual server with CentOS 6.2 x64 and assigned redhat 6.2 x64 as linux type. But when i start VM it failed to start. I read libvirtd log and it write a error on libvirtd.log: 2012-04-25 21:04:59.952+0000: 1705: error : qemuProcessReadLogOutput:1005 : internal error Process exited while reading console log output: Supported machines are: pc RHEL 6.2.0 PC (alias of rhel6.2.0) rhel6.2.0 RHEL 6.2.0 PC (default) rhel6.1.0 RHEL 6.1.0 PC rhel6.0.0 RHEL 6.0.0 PC rhel5.5.0 RHEL 5.5.0 PC rhel5.4.4 RHEL 5.4.4 PC rhel5.4.0 RHEL 5.4.0 PC What is the problem.
