Comment 2 for bug 1078219

Thx for reply me !
I have looked "https://bugs.launchpad.net/nova/+bug/1076308" and fix the code in "nova/virt/libvirt/driver.py",but it raise new error,here is the key log:

raise exception.InvalidCPUInfo(reason=m % locals())\n\nInvalidCPUInfo: Unacceptable CPU info: CPU doesn\'t have compatibility.\n\n0\n\nRefer to http://libvirt.org/html/libvirt-libvirt.html#virCPUCompareResult\n\n'].

what can i do for this ? My compute node node2 and node3 can create instances by itself.
