function Restart-PVEVM {
  <#
  .SYNOPSIS
  Resets QEMU virtual machines (hard restart).
  .DESCRIPTION
  Like pressing a physical reset button: the guest restarts immediately without shutting down, and data
  not yet written can be lost. For a clean restart use Restart-PVEVMGuest.

  Prompts for confirmation by default (ConfirmImpact High). A VM that is not running is skipped with a
  warning and written unchanged.
  .PARAMETER Name
  VM name(s). Wildcards allowed.
  .PARAMETER VMId
  VM ID(s). Binds from piped PVEPS.VM objects.
  .PARAMETER RunAsync
  Return the PVE task(s) at once instead of waiting.
  .PARAMETER Server
  Connection(s) to use. Defaults to the default connection; binds from piped objects.
  .EXAMPLE
  Restart-PVEVM web01 -Confirm:$false
