I have a cluster of 4 nodes with ceph, version:

The operation of multiple Windows VM in a cluster is not stable and with occasional reboots.
For example, I can't start another machine on this node without problems. And the fourth one is generally disabled when loading.

This does not depend on the storage used. However, everything is much more stable if each machine is allocated only one processor with a single core.
Am I the only one facing this, or is this a known problem?
