Start, stop, and pause a VM

ZRS lists VMs registered with libvirt, including VMs created outside ZRS. Open a VM from the VMs page to access its power controls.

Start a VM #

1. Open VMs and select the VM name.
2. Select Start in the page header.
3. Wait for the status to change to Running.

Running means the VM is powered on, the operating system and services inside it may still be starting.

Stop or restart #

1. Save any work inside the VM.
2. Select Stop to request a clean shutdown. To restart instead, open More actions (the three-dot menu) and select Restart.
3. For a stop, wait until the status reads Shutdown before changing hardware.

Restart requests a reboot from the guest operating system.

Pause and resume #

1. While the VM is running, open More actions and select Pause.
2. To continue, select Resume.

Pause stops guest execution while keeping its memory allocated on the host. Services inside the VM stop responding until Resume. Paused state isn't saved to disk and doesn't survive a host restart.

When shutdown does not finish #

Dismiss the slow-shutdown notice to continue waiting.

To cut power immediately, open More actions, select Force shutdown, and confirm.

If the shutdown request times out, ZRS leaves the VM running. It won't force it off automatically.

Start with the host #

On the VM detail page, enable Autostart to start it when the host boots. Autostart is unavailable for transient VMs, which lack a saved configuration.
