If you have a lease, detaching the network used to access the leases will cause sanlock to terminate the vm and expire the lease. In this case the system should start the vm on another host. Note that if you have multiple networks, and the network used by the vm disks is different from the network used to access the leases, all this may not work in a useful way. Either the leases will not be accessible while the vm disks are accessible, leading to killing a good working vm, or the vm disk are not accessible, pausing the vm, but since the leases are still accessible, the vm will not release the lease and the system will not be able to start the vm elsewhere. Maybe you can expose some of the ceph storage using cephfs for the leases? This will make it more likely that the leases storage domain will fail when there is some issue with your ceph cluster. Another option is to expose ceph block device using iscsi, and use this iscsi storage domain for the leases. But note that this makes your iscsi gateway host a single point on failure.
