Fixed In Version: | qemu-kvm-0.12.1.2-2.114.el6 | Doc Type: | Bug Fix | |
Doc Text: |
Cause: qemu-kvm didn't have spice/qxl high resolution modes enabled.
Consequence: qemu-kvm did not allow a user to select a resolution higher than 1920x1080, which may have been rather limiting.
Fix: Remove the QXL_HIRES_MODES #define. Make the highres modes depend on the size of the vga ram (and draw area) instead. This enables some of the highres modes as RHEL-6.0 has VGA_RAM_SIZE set to 16 MB (unlike upstream qemu which has 8MB only).
Result: maximum supported resolution of spice/qxl increased to 2560x1600.

Description
Red Hat Bugzilla
2009-01-27 18:31:14 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. We'll look into if this is possible without too much work. Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. Thank you for your bug report. This issue was evaluated for inclusion in the current release of Red Hat Enterprise Linux. Unfortunately, we are unable to address this request in the current release. Because we are in the final stage of Red Hat Enterprise Linux 6 development, only significant, release-blocking issues involving serious regressions and data corruption can be considered. If you believe this issue meets the release blocking criteria as defined and communicated to you by your Red Hat Support representative, please ask your representative to file this issue as a blocker for the current release. Otherwise, ask that it be evaluated for inclusion in the next minor release of Red Hat Enterprise Linux. A qemu-kvm patch was submitted pointing to this BZ, but the component is spice-common. If patches only for qemu-kvm are needed, the component needs to be changed to qemu-kvm. If patche for both spice and qemu-kvm packages are needed, a qemu-kvm BZ is needed to (it can be simply a clone of this bug[1]). [1] Please, if cloning, always include a comment at the top of the BZ description explaining why it is being cloned. Dynamic allocation of framebuffers is necessary for good multi-monitor support too. What is the maximum resolution available by default as a result of this work? Re #24: 2560x1600 Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Previously, qemu-kvm did not allow a user to select a resolution higher than 1920x1080, which may have been rather limiting.
