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 8 Golita Yue 2011-02-15 06:53:28 UTC 
Hi Gerd,

I tested this bug on guest:winXP-32 with qemu-kvm-0.12.1.2-2.133.el6, Failed. 
The max supported Modes is 1920*1440. (with patch) Could not find 2560*1440.

I tested again on the same guest with qemu-kvm-0.12.1.2-2.113.el6,
the max supported Modes is 2560*1600. (without patch)

Why the max supported resolution changes to more small(with patch)?
Comment 9 Gerd Hoffmann 2011-02-16 11:27:31 UTC 
What guest and what drivers you are testing with?
Comment 11 Gerd Hoffmann 2011-02-17 11:44:01 UTC 
The driver referenced requires the new qxl device added by the patches and doesn't work with qemu-kvm-0.12.1.2-2.113.el6 ...

Comment 17 Alon Levy 2011-04-04 12:26:21 UTC 
The qemu-kvm support is already there, the remaining problem is a driver one (in X the current driver is good enough, but the windows driver has a check that removes modes with >2000 in any coordinate), the cloned bug #690417 was openned for that.

Comment 18 Alon Levy 2011-04-06 14:49:31 UTC 
This bug was reopened after (or because of/related to) comment 8, since testing on windows xp failed. However, this turned out to be specifically a windows driver bug, for which bug #690417 was cloned. qemu-kvm is in fact good enough and so I'm returning this bug to MODIFIED (no further changes to qemu-kvm are needed). See #690417 comment 3 for a driver scratch build pending qa to verify the fix. Linux guests can already see 2560x1440 with the qxl xorg driver.

Verified in qemu-kvm-0.12.1.2-2.133.el6.

Tested in linux and windows guest, all can switch the screen resolution to 2560*1440.
