We have many cases of failed migrations, and reducing the load on the respective VMs made
migration possible. Using "Suspend workload when needed" did not help either
with the migrations, which only worked when stopping services on the VMs, thus reducing
I was therefore trying to tweak the migration downtime setting. The suggested way of doing
this is by using the Legacy migration policy.
That being said, I am unable to find the Legacy migration policy in the VM Host tab, nor
in the cluster's "Migration policy" tab. I cannot find any mention of it

migration downtime" (only available when using the Legacy migration policy) does
exist in the interface - but I cannot find the Legacy policy itself.
The only policies present are Minimal downtime (default for cluster), Post-copy migration

PS. Setting DefaultMaximumMigrationDowntime=20000 as default did not have any effect,
presumably because the system uses one of the 3 pre-defined policies and ignores the
