When migrating VMs (e.g. "test") via ganeti from one node to another,
its xen config file (located in /etc/xen/test in this case) gets deleted
while moving.
The target node does not receive this xen config file, which makes it
impossible to migrate it back again.
Error while migrating the VM back to the original node:
2021-01-26 13:30:30,091: job-197 pid=11195 ERROR Failed fetching source
migration information from node2: Failed to fetch migration information:
Failed to load Xen config file: [Errno 2] No such file or directory:
'/etc/xen/test'
If the xen config gets copied manually to all nodes, migration is
possible once per node (because while migrating the config gets deleted
again), otherwise the same error occurs every time.
