libvirtError: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainMigratePerform3Params)
Hi everyone, I have a question that you may be able to help me with. I had a live block migration of a qemu-kvm guest fail (initiated via nova), in which the guest remained running on the source, but if I try to re-initiate the live migration it returns libvirtError: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainMigratePerform3Params). Looking at

virsh does no longer respond to commands
Hi, after a recent live backup done with a snapshot, blockcommit failed and a subsequent (manual) blockjob abort got stuck. Now we are unable to do basic operations on the virtual machine like if it was frozen and when issuing another command we see the following: $ virsh shutdown $domain error: Failed to shutdown domain $domain error: Timed out during operation: cannot acquire state change lock

Is that true? Undefining the VM will not be necessary after two things happen: 1. qemu supports persistent

virsh blockcommit fails regularily (was: virtual drive performance)
Hi, a small update on this. We have migrated the virtualized host to use the virtio drivers and now the drive performance is improved so that we can see a constant transfer rate. Before it used to be the same rate but regularly dropped to a few bytes/sec for a few seconds and then was fast again. However we still observe that the following fails regularily: $ virsh snapshot-create-as --domain

recovering from deleted snapshot
I have an automatic process setup. It's still pretty new and obviously in need of better error handling because now I find myself in a bad state. I run snapshot-create-as across all my vms, then do zfs replication to the target backup system, then blockcommit everything. virsh snapshot-create-as --domain $vm snap --diskspec $DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic
