Description Doron Fediuck 2013-02-06 16:43:35 UTC
Description of problem:
This BZ is meant to handle a missing fix already merged in upstream VDSM.

We should support passing -cpu host to a virtual machine.

Use case :  User wants maximum performance from a virtual machine and does not care about migration.

This should be presented as an advanced CPU option and should block migration.

Comment 1 Laszlo Hornyak 2013-02-06 16:52:43 UTC
this is a bug to port this http://gerrit.ovirt.org/#/c/9507/ to downstream

Comment 4 Ido Begun 2013-03-21 06:31:05 UTC
OK - SF10.1

A VM with CPU mode of "host_passthrough" is running with '-cpu host'.
