The host system uses OpenSuSE 12.1, too. First I thought it could be related to virtio drivers. According to a Red Hat bugreport (https://bugzilla.redhat.com/show_bug.cgi?id=802118). But switching to ide/rtl8139 didn’t help. After some additional searching I found a second matching bug report: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=757382 Some lines in my libvirtd.log are found in the Fedora bug report above. 18:18:30.967: 2393: error : virNetSocketReadWire:912 : End of file while reading data: Input/output error 18:18:36.960: 2393: error : virNetSocketReadWire:912 : End of file while reading data: Input/output error 18:19:04.000: 2394: error : qemuDomainObjBeginJobInternal:772 : Timed out during operation: cannot acquire state change lock 18:19:05.893: 2393: error : qemuMonitorIO:577 : internal error End of file from monitor 18:19:15.232: 2395: warning : qemuDomainObjTaint:1110 : Domain id=3 name='virtual1' uuid=7c7f469c-3d57-7bf5-c81a-d815966a948b is tainted: high-privileges Reproducible: Always Steps to Reproduce: 1. Start a KVM guest with any operating system. 2. Wait a few days/hours. 3. The system got unresponsive. Actual Results: When I try to restart the guest (virsh restart virtual1) it says: Fehler: Neustart der Domain virtual1 gescheitert (restart of domain failed) Fehler: Timed out during operation: cannot acquire state change lock Expected Results: My KVM guests should work properly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
