Description Jamie Bainbridge 2012-01-02 22:31:03 UTC 
Description of problem:

Previously fixed issue https://bugzilla.redhat.com/show_bug.cgi?id=692355 (released as errata http://rhn.redhat.com/errata/RHBA-2011-1513.html) includes behavior which customers should be aware of. As noted in Comment 8 of https://bugzilla.redhat.com/show_bug.cgi?id=766216 Engineering believe this should be in the errata notes.

Something like this would work:

Previously, libvirt assigned PCI IDs to virtual devices on an "as needed" basis. This has been changed to specifically reserve specific device IDs for virtual device types, notably 0x01 for the IDE controller and 0x02 for the VGA device. Customers migrating guests with other device types on these device IDs will need to manually edit their guest XML files to move devices off reserved IDs.
