Which method should an engineer use to deal with a long-standing contention issue between any two VMs on the same host?

Adjusting resource reservation limits allows an administrator to guarantee a specific amount of CPU, memory, or other resources to a particular VM, preventing other VMs from consuming those resources and thus mitigating long-standing contention issues by ensuring critical VMs have what they need.

Live migrating a VM might temporarily alleviate contention but does not address the underlying resource allocation strategy on the host.

Resetting a VM merely reboots the operating system within it and does not solve resource contention on the host.

Resetting the host would impact all VMs and cause downtime without addressing the specific resource contention configuration between VMs.
