Fixed In Version: libvirt-5.6.0-6.2.el8
Doc Type: Bug Fix
Doc Text:
Cause: When doing a blockcommit libvirt modifies access to image files so that qemu can do requested block job. Later, when the job is finished, the access is restored to the original state - i.e. xattrs are removed. However, if user kills qemu before it finishes its job, the access is not restored and some XATTRs ale left behind. This leaves the domain unable to start again. Consequence: A domain is unable to start again. Fix: When cleaning up domain on destroy (or after qemu crashed) libvirt deliberately clears stale XATTRs. Result: The domain can start again and again.
