Hi Kumar,
when the engine starts a VM it also specifies a machine type.
The machine types supported by an host depend on the system (RHEL/Fedora)
and you can get the list with:
# vdsClient 0 getVdsCaps | grep emulatedMachines
emulatedMachines = ['pc-1.1', 'pc', 'pc-1.0', 'pc-0.15', ...
Once you discovered the types supported by your hosts you can configure
the engine with the correct value:
http://www.ovirt.org/wiki/Engine_Node_Integration
psql -U postgres engine -c "update vdc_options set option_value='pc-0.14'
where option_name='EmulatedMachine' and version='3.0';"
I assume that you ran the command above but your VDSM hosts are rhel6,
so you would need to use the "rhel6.2.0" value instead.
I believe that the value "pc" is an alias that works both for RHEL and
Fedora and it might be handy for testing, but in general I really discourage
its use because it would allow a mixed cluster of RHEL and Fedora hosts
which could be problematic in case of live migrations.
