Question
On a cluster of ESXi 6.5 hosts, a small number of virtual machines have much larger resource requirements than others. Some hosts have a large number of virtual machines while others have very few. The administrator enables DRS with DRS VM distribution to evenly balance the number of virtual machines on each host. Which will be the outcome?
Options
- AVirtual machines will be moved without regard to resource contention in the cluster, and the
- BVirtual machines will not change hosts unless they are power-cycled or vMotioned manually.
- CVirtual machines will not be moved if it results in severe resource contention in the cluster, and
- DDRS VM distribution will not evenly balance the number of virtual machines on each host unless

Why each option
Enabling DRS VM Distribution balances VMs by count per host, not by resource consumption, so VMs can be relocated to hosts that then become resource-contended because the feature ignores actual workload weight.
DRS VM Distribution equalizes the number of virtual machines per host without evaluating each VM's CPU or memory footprint. In a cluster where some VMs have much larger resource requirements, an even VM count spread can overload certain hosts, meaning migrations occur without regard to resulting resource contention - exactly the behavior described in this answer.
Enabling DRS VM Distribution actively triggers vMotion operations to equalize VM counts; VMs do not stay on their current hosts unless the per-host count is already balanced.
DRS VM Distribution does not evaluate resource contention as a blocking condition - it only checks VM count, so it will not suppress moves that cause severe resource pressure.
VM Distribution operates independently of other cluster settings; it does not require specific migration thresholds or minimum cluster sizes to function.
Concept tested: DRS VM Distribution ignoring resource contention on migration
