Hi,
I was trying to explore more about fencing option supported in ovirt. But getting lost in documents.
My requirement is to fence at VM level rather than host level. e.g let assume VM1.1, VM1.2,VM1.3 are running on host1 and VM2.1,VM2.2 VM2.3 running on host2. Suppose due to some error only VM1.1 goes down [Note: VM1.2 and VM1.3 in running state] then VM2.1 must come up.
Can I get to know whether such functionality is supported by ovirt ? If yes, would you please explain also how it work or would you share refernece for me to refer and understand it ? if yes, is it configurable by python sdk ?
Fencing in the VM level is not available yet, but will be possible once we have vm-leases: https://www.ovirt.org/develop/release-management/features/storage/vm-leases/ On top of this, we will support automatic failover of vms: https://github.com/oVirt/ovirt-site/pull/586/commits/77669161397ebf4cc15c66e... This should be available in 4.1, currently blocked by libvirt bug: https://bugzilla.redhat.com/1403691 Once a vm has a lease, you can revoke the lease from another host, causing sanlock on the original host to terminate the vm using sanlock_request() api. When this will be implemented, we can expose this via the REST API and the SDK. Nir
Thanks, ~Rohit
