http://bugzilla.opensuse.org/show_bug.cgi?id=1202541 Bug ID: 1202541 Summary: KVM/libvirt bug on download.o.o VM host? Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: All Status: NEW Severity: Normal Priority: P5 - None Component: KVM Assignee: kvm-bugs@suse.de Reporter: bwiedemann@suse.com QA Contact: qa-bugs@suse.de Found By: Development Blocker: --- Created attachment 860917 --> http://bugzilla.opensuse.org/attachment.cgi?id=860917&action=edit pontifex messages Tonight we had some hours of outage of download.opensuse.org While the last messages were about OOM, a closer look made me think that some bug in our live-migration or KVM layer might be to blame. download.o.o runs as a VM "pontifex2" on a KVM cluster with a shared FC block-storage. For Thursday maintenance we have scripts to live-migrate all VMs to an empty host before we upgrade+reboot the host. Yesterday, atreju6 was rebooted at 09:21 UTC Then it took some minutes for the next host to be evacuated... /var/log/libvirt/qemu/pontifex2.log shows 2022-08-18 09:38:40.092+0000: starting up libvirt version: 5.1.0, qemu version: 3.1.1SUSE Linux Enterprise 12, kernel: 4.12.14-122.130-default 2022-08-18 09:38:40.092+0000: Domain id=27 is tainted: host-cpu The pontifex2 log has 2022-08-18T09:40:59 general protection fault, probably for non-canonical address 0x17ffffc0000010: 0000 [#1] PREEMPT SMP NOPTI and from there it kept throwing 292 backtraces until it paniced tonight. -- You are receiving this mail because: You are on the CC list for the bug.
