Configuring virtual machine hibernation in vSphere can help save energy and reduce costs. When a virtual machine hibernates, it saves the contents of its memory to disk and shuts down all devices except for the memory. This allows the virtual machine to quickly resume its operation without needing to boot up from scratch.
To configure virtual machine hibernation in vSphere, follow these steps:
1. Log in to the vSphere Client and connect to your vSphere environment.
1. Select the virtual machine that you want to configure for hibernation.
1. Click on the “Edit Settings” option for the virtual machine.
1. In the Virtual Machine Properties dialog box, select the “Options” tab.
1. Click on “Power Management” and then check the “Enable CPU power management” box.
1. In the “Advanced” section, check the “Enable virtual machine hibernation” box.
1. Set the hibernation time limit using the “Hibernation Time Limit (in minutes)” slider. This specifies the amount of idle time before the virtual machine is put into hibernation mode.
1. Click “OK” to save your changes.
When the virtual machine remains idle for the specified amount of time, it will hibernate to save energy and reduce costs. The contents of its memory will be saved to disk and all devices except for memory will be shut down. When the virtual machine is needed again, it can resume operation quickly without needing to boot up from scratch.
By configuring virtual machine hibernation in vSphere, you can reduce energy consumption and save money on power costs while also minimizing downtime and improving system efficiency.
