RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 Vadim Rozenfeld 2014-01-01 05:06:16 UTC
Do we have qxl-wddm driver installed on this system?

Could you please install the latest seabios and give a try to 
the new qxl driver available at 
https://brewweb.devel.redhat.com//taskinfo?taskID=6798028 ? 

(no need in specifying qxl-vga.revision
for this driver to make it working).

Thanks,
Vadim.

Comment 3 Vadim Rozenfeld 2014-01-02 22:11:02 UTC
There is a new build available at
https://brewweb.devel.redhat.com/buildinfo?buildID=323507

Comment 5 mazhang 2014-01-03 03:32:31 UTC
Test this problem with the latest seabios and qxlwddm.

Host:
seabios-1.7.2.2-6.el7.x86_64
qemu-kvm-rhev-1.5.3-30.el7.x86_64

Guest:
win8.1-32
qxlwddm-0.3-2

Result:
Guest display normal with/without specifying qxl-vga.revision.

Comment 6 David Blechter 2014-07-28 10:20:14 UTC
this component is for spice-server only, please move ASAP to the appropriate component

Comment 10 Mike Cao 2014-08-15 06:36:37 UTC
Move status to Verified according to comment #5

Comment 13 Mike Cao 2015-01-22 13:27:35 UTC
No need to add qxl driver bug to virtio-win errata ,closing
