This surprises me. Engine should have used the same emulatedMachine
value, independent of the initial host. Could you share the vdsm.log
lines mentionioning "emulatedMachine" in both cases?

Hi Dan,
sorry for coming back this late. I checked it and the default
emulatedMachine is pc. And machine pc differs in the definition between
6.3 and 6.4.
virsh 6.3:
<guest>
<os_type>hvm</os_type>
<arch name='x86_64'>
<wordsize>64</wordsize>
<emulator>/usr/libexec/qemu-kvm</emulator>
<machine>rhel6.3.0</machine>
<machine canonical='rhel6.3.0'>pc</machine>
<machine>rhel6.2.0</machine>
<machine>rhel6.1.0</machine>
<machine>rhel6.0.0</machine>
<machine>rhel5.5.0</machine>
<machine>rhel5.4.4</machine>
