Power down the VM and reduce the memory a little bit but keep the maximum memory value the
same or larger.
Then power it up and extend the ram to the same value the VM had.
It's a wild guess... So don't expect miracles.

I also checked the vdsm.log on the destination host which is showing an
error like this.

Does anybody know how to resolve this? The destination host is able to
run VMs and I've been able to move a few VMs by shutting down and doing
a restart however I'd like to do a live migration if possible.

You do not have enough available memory on the target. It happens with
high overcommit, migrating to a new host require more space initially
than what it currently takes on source. Check avail mem for scheduling
on the other host
Host Maintenance just tries over and over, so there’s a better chance
it succeeds eventually.
