raniers1 opened a new issue, #13098:
URL: https://github.com/apache/cloudstack/issues/13098
### problem
When automated DRS is enabled and a cluster contains a VM with a vGPU
passthrough profile, the DRS plan generation fails for the entire cluster
with an unhandled `InvalidParameterValueException`. No migrations are
planned
for any VM in the cluster, even for the ones that are perfectly migratable.
Error log:
ERROR [o.a.c.c.ClusterDrsServiceImpl] Unable to generate DRS plans for
cluster
Cluster {id: "3", name: "princeton-cluster01"}
com.cloud.exception.InvalidParameterValueException: Unsupported operation,
VM uses host passthrough, cannot migrate

### versions
ACS 4.21.0.0, KVM
### The steps to reproduce the bug
1. Enable automated DRS on a cluster (cluster.drs.enabled=true)
2. Have at least one VM in the cluster using a GPU passthrough profile
3. Wait for the DRS poll cycle to run
### What to do about it?
In `getBestMigration`, catch the `InvalidParameterValueException` thrown by
`listHostsForMigrationOfVM` inside the VM loop and skip the VM with a debug
log. This allows the remaining eligible VMs to still be evaluated normally.
