disabling vmware device emulation breaks old->new migration
Last modified: 2013-01-09 18:33:43 EST
+++ 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 --- Additional comment from pm-rhel@redhat.com on 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. ** --- Additional comment from bburns@redhat.com on 2010-07-20 08:31:53 EDT --- Moved BZ to 6.1, release note is needed for 6.0. --- Additional comment from rlerch@redhat.com on 2010-08-30 19:19:39 EDT --- This bug appears to be a known issue that is to be documented in the Technical Notes for the RHEL 6.0 Release. Please provide information covering the following 4 dot points in the technical notes field above: * Cause What actions or circumstances cause the bug to present (if known). Note: if the cause is not known or is not fully diagnosed, current hypotheses or theories should be noted. * Consequence What happens when the bug presents. * Workaround What actions, if any, reduce the bug’s effects or prevent it from presenting entirely. * Result If the bug’s effect is only reduced, what consequences still flow; if the bug is prevented, what restrictions does the workaround impose. --- Additional comment from ddumas@redhat.com on 2010-09-10 16:04:50 EDT --- Technical note added.

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.

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. --- Additional comment from ehabkost@redhat.com on 2011-02-03 10:51:22 EST --- Patch(es) posted for review and queued.
