Description Eduardo Habkost 2010-07-19 15:44:17 EDT
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 Product and Program Management 2010-07-19 15:58:07 EDT
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 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.
Comment 15 Eduardo Habkost 2011-02-15 11:23:29 EST
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 00:29:16 EST
Patches have been applied and work well.
So this bug have been verified.
