we have a SAN with an iSCSI target formatted with OCF2 which contains qcow2 images for a bunch of virtual servers. We’re running Ubuntu 10.04.1 LTS, 64bit, Libvirt 0.8.2.
When trying to migrate from one server to another, it has recently started complaining and will not migrate:
# virsh migrate --live dir2 qemu+ssh://host2/system
error: Timed out during operation: cannot acquire state change lock
And in the logs of Host2
qemu: warning: error while loading state for instance 0x0 of device 'ram'
load of migration failed
and the messages say:
Nov 19 10:25:14 host2 libvirtd: 10:25:14.606: warning : qemudParsePCIDeviceStrs:1407 : Unexpected exit status '1', qemu probably failed
Host1 will quietly fail and the VM will keep running, but Host2 will have the “paused” version of “dir2” (or other VMs). After initiating the migrate again, it will then complain that “dir2” is already running. Which it is.
I’m loosing the ability to “destroy” servers, and beginning to resort to “kill -9” them.Anyone have any ideas!?!?!?
