+++ This bug was initially created as a clone of Bug #616187 +++

Description of problem:
On RHEL5 we used the --disable-vmware option to disable th VMWare device emulation on qemu-kvm. On RHEL6 this feature is enabled at build time (as the patch to make it optional was not included upstream), but it is not a supported feature.


Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.96.el6

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Given this has been released noted as not supported (and it wasn't ever really supported), I don't see this as that critical.  The current priority of low seems reasonable for now.  

However, it should be pretty straightforward by either adding the disable flag back in or just disabling it altogether for 6.1.  Thus, I'm setting this BZ to 'KVMtier3' for now with a dev_ack+ assuming its easy to address for 6.1.  If that's not the case, please let me know and provide more info within this BZ.  Thanks, steve

Hi Eduardo,
According to your description of problem, I checked and booted a guest on rhel6, it seems that vmware device works fine. Here is the cli, if any mistake, please correct me.

Created attachment 473971 [details]
vmware device works correctly

--- Additional comment from ehabkost on 2011-01-31 15:03:15 EST ---

The code to disable the vmware devices is not present upstream, so we need to include it upstream first, before adding --disable-vmware to our code. Setting Conditional NAK: Upstream.

--- Additional comment from pm-rhel on 2011-01-31 15:21:08 EST ---

This bug report previously had all acks and release flags approved.
However since at least one of its acks has been changed, the
release flags have been reset to ? by the bugbot (pm-rhel).  The
ack needs to become approved before the release flags can become
approved again.
