http://bugzilla.suse.com/show_bug.cgi?id=979848 Bug ID: 979848 Summary: vmwrite errors Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KVM Assignee: kvm-bugs@forge.provo.novell.com Reporter: adrian@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I did an update of all of our OBS build workers from openSUSE 13.2 to 42.1 last week and I am currently debugging some speed regressions. I am not sure if this is related, but I stumbled over these "vmwrite error" lines in many of our cloud build hosts. They seem to be new. Can they be the root of perfomance problems?
