Question

An administrator wants to prevent a priority virtual machine that resides in a vSphere DRS cluster from migrating to other hosts in the cluster. What configuration step will accomplish this without affecting other virtual machines?

Options

  • ASet VM Overrides to Partially Automated for this virtual machine.
  • BConfigure a Virtual Machines to Hosts rule with the setting Must run on hosts in group.
  • CConfigure a Virtual Machines to Hosts rule with the setting Should run on hosts in group.
  • DSet VM Overrides to Manual for this virtual machine.

Why each option

Setting a VM Override to Manual prevents DRS from automatically migrating a specific VM while leaving all other VMs at their existing automation levels.

ASet VM Overrides to Partially Automated for this virtual machine.

Partially Automated mode still allows DRS to automatically place the VM during initial power-on, and ongoing migration recommendations can still be acted upon, so it does not reliably prevent the VM from being moved.

BConfigure a Virtual Machines to Hosts rule with the setting Must run on hosts in group.

A 'Must run on hosts in group' rule restricts the set of eligible hosts for the VM but does not prevent DRS from automatically migrating it between hosts within that defined group.

CConfigure a Virtual Machines to Hosts rule with the setting Should run on hosts in group.

A 'Should run on hosts in group' rule is a soft affinity rule that DRS can violate when load balancing demands it, so it provides no guarantee against migration.

DSet VM Overrides to Manual for this virtual machine.Correct

When a VM Override is configured to Manual, DRS generates migration recommendations for that VM but will not automatically execute any vMotion operation on it, effectively preventing unattended migration. The administrator must explicitly approve any move for this VM, which satisfies the requirement to keep it on its current host. This override is scoped only to the selected VM, so no other VMs in the cluster are affected.
