Description of problem:
We want to migrate VM from Node-to-Node, but it is failing with below error.
Linux:
VirtualMachineInstance migration uid 29acdc88-b8d7-4ab2-add2-1131a6d8868a failed. reason:Live migration failed error encountered during MigrateToURI3 libvirt api call: virError(Code=1, Domain=10, Message='internal error: unable to execute QEMU command 'cont': Failed to get "write" lock')
Windows:
server error. command SyncVMI failed: "LibvirtError(Code=1, Domain=10, Message='internal error: unable to execute QEMU command 'cont': Failed to get \"consistent read\" lock')"
> I am using Ceph(not RedHat Ceph) as my storage class with RWX mode.
> now, if used node selector in my YAML, VM runs on the particular node without any error.
> On initiating node to node migration from UI, it creates 1 more virt launcher pod in another node, but it goes on into completion rather than continue to stay in running. Then, migration fails with above error.
> In the second virt-launcher pod, on doing virsh list, we don't find any VMs running.
> Exisitng virt-launcher pod, we observe
