Running and stopping VMs and environments
VMs have the same power states as physical machines. They can be run, shut down, reset, and powered off. Most VMs also support suspend.
Also like physical machines, VMs require some time to change power states. You can’t interact with a VM while it’s changing power states.
The available power actions are:
Run – Starts a suspended or powered off VM.
Suspend – Suspends a running VM. Preserves the running state of the VM by writing the contents of RAM (including running programs and active data) to the disk. When you run a suspended VM, the RAM state is restored from disk so that you can resume from where you left off.
The Suspend action works only for x86 VMs with 256 GB or RAM or less. Neither Power A particular type of CPU that supports IBM i, AIX, and Linux in Skytap Cloud. VMs nor x86 VMs with more than 256 GB of RAM can be suspended.
Shut down – Safely shuts down a running VM.
Shut down works automatically for Power VMs, but requires VMware Tools to be installed on x86 VMs.
Power Options (drop-down menu):
- Shut down – (see above)
- Reset – Powers off and then powers on a running VM, leaving any resources (such as ISOs) mounted. Reset applies only to individual VMs.
- Power off – Forces power off, effectively “pulling the plug” on a running or suspended VM.
Reset and Power off may cause data corruption; use them only for unresponsive VMs.
Run, suspend, or shut down VMs in an environment
You can run, suspend, or shut down all or some of the VMs in an environment.
- Use the VM-level power controls to run, suspend, or shut down a single VM.
- Use the multi-select power controls to run, suspend, or shut down all of the selected VMs in the environment. Each VM has a checkbox you can select or deselect.
- Use environment-level power controls to run, suspend, or shut down all of the VMs in the environment.
- While VMs are changing power state, they’re not available for use. For more information, see Error message: “The VM guest OS is not responding.”.
- (Run, Suspend, and Shut Down) display based on the current power state and capabilities of the VMs.
- To display additional power options, click (Power options).
- If you click a power action that doesn’t apply to all of the selected VMs, only VMs that can change to that power state are affected. For example, if you try to suspend a set of selected VMs, only running VMs in the selected group are suspended. VMs that are already powered off or suspended do not change state.
Run or shut down multiple environments
From the navigation bar, click Environments. Click the Environments tab.
- Click the (Select) button to expose checkboxes for each environment.
- Select any environments you want to run or shut down; click the top checkbox to select all of the environments on the page.
- Click (Run) or (Shut down) in the multi-select toolbar.
