A VM property that determines which ESX releases the VM is able to run on and what virtual hardware is available to it, for example firmware type, the vCPU limit and memory limit.
Also called hardware version.

Terms in this definition
- property
In VCF Operations, an attribute describing how an object is configured, such as its vCPU count. Unlike a metric, it captures state rather than performance over time, and it can feed symptom definitions, views, dashboards and reports.
- ESX
VMware's bare-metal hypervisor, installed on each host in a VCF fleet. Up to version 9.0 it was known as ESXi.
- vCPU
What a VM sees as a processor, with ESX scheduling the work onto physical cores. In esxtop, the CPU panel shows these as VCPU worlds for every VM.
- LIMIT
Caps how many rows a SQL query gives back. Don't treat what you get as random or representative.
Related terms
- Changed Block Tracking
ESXi migrations with Nutanix Move depend on this on the source VMs, which must be at hardware version 7 or above. The VMware capability records which blocks have altered since the previous copy.
- Per-VM EVC
EVC configured on a single virtual machine instead of on the whole cluster. Disabled by default, it requires virtual hardware version 14 or later, can only be changed while the VM is off, and moves with the VM when it changes cluster.
- Supervisor onboarding
Migration type in HCX for moving traditional VMs into a Supervisor namespace, via Bulk migration to staging followed by an import. It requires HCX 9.0 on both sides and VMs at hardware version 17+ with VMware Tools; as each VM restarts, downtime-intolerant workloads should avoid it.
