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.

As qemu-kvm and libvirt don't support sdl.refer Bug 633326 - Fails to reject unsupported graphics type such as 'sdl',the type sdl should be removed from the error info.
# virsh start demotest
error: Failed to start domain demotest
error: unsupported configuration: only 1 graphics device of each type (sdl, vnc, spice) is supported

Actual results：
sdl is included in the error info in step 2.

Expected results:

Additional info:
On rhel7,qemu-kvm doesn't provide support sdl,refer to bug 1049813,the issue can also be reproduced on rhel7.

Comment 2 Daniel Berrangé 2014-05-23 09:36:50 UTC

You are conflating support in libvirt with support in KVM. A software collection or add-on project like RDO may ship a different KVM binary from the one in base-RHEL that *does* have SDL support included. So it is not appropriate to change this in libvirt.
