Description Eduardo Habkost 2010-07-19 19:44:17 UTC
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

Comment 1 RHEL Program Management 2010-07-19 19:58:07 UTC
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. **

vmware device works correctly

Comment 10 Eduardo Habkost 2011-01-31 20:03:15 UTC
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.

Comment 15 Eduardo Habkost 2011-02-15 16:23:29 UTC
Disabling the devices will break migration from older versions (thanks Paolo Bonzini for spotting that). bug #677712 was open for the issue.

Comment 17 YangFeng 2011-03-04 05:29:16 UTC
Patches have been applied and work well.
So this bug have been verified.
