Description Doron Fediuck 2013-02-06 11:43:35 EST
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.

OK - SF10.1

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