qemu: Check for domain being active on successful job acquire
As this is needed. Although some functions check for domain
being active before obtaining job, we need to check it after,
because obtaining job unlocks domain object, during which
a state of domain can be changed.
I'm marking this as POST, so that the above patch can be included in the next F16 libvirt build. libvirt-0.9.6-5.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/libvirt-0.9.6-5.fc16 Package libvirt-0.9.6-5.fc16: * should fix your issue, * was pushed to the Fedora 16 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing libvirt-0.9.6-5.fc16' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-3067/libvirt-0.9.6-5.fc16 then log in and leave karma (feedback). libvirt-0.9.6-5.fc16 has been pushed to the Fedora 16 stable repository. If problems still persist, please make note of it in this bug report. |
