There is no support for that in libvirt. Either we must addit ad a
feature (patches welcome), but if that's there just for a workaround,
I would suggest chasing the original bug.
If you just want to check that the workaround works, you could check
how the '-cpu ' parameter looks like when the domain is running and
then use the unsupported way of adding parameters to the qemu
commandline to specify the -cpu parameter again (qemu should use the
last one, so it should work), something like this:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain>/qemu/1.0'>
...
<qemu:commandline>
<qemu:arg value='-cpu'/>
<qemu:arg value='${CPU_SPEC},-kvm_steal_time'/>
</qemu:commandline>
</domain>
where ${CPU_SPEC} is the next parameter after the '-cpu' one from the
command line, so for qemu command line similar to this:
qemu-kvm ... -cpu Nehalem,+feat,something ...
the line in XML would be:
<qemu:arg value='Nehalem,+feat,something,-kvm_steal_time'/>
Thank You Martin, that helped.
