Re: [libvirt-users] Migrating fails with "Timed out during operation: cannot acquire state change lock"

After recently upgrading to 0.9.11 (as shipped with Fedora 17), I was just trying to migrate a qemu domain from one host to another (using virDomainMigrateToURI()), when I got this error message: Unsafe migration: Migration may lead to data corruption if disks use cache != none Okay, this is explainable (if a bit disappointing - I would have hoped that qemu would be able to disable disk caches before migration and then reenable them afterwards...). However, the next time I tried migrating the same domain, I got this error message after about 30 seconds: Timed out during operation: cannot acquire state change lock
