You can adjust CPU and RAM resources for all VMs. Some VMs can have their CPU and RAM adjusted without needing to be powered off using the “resize without reboot” option. Windows 2008 and Windows 7 VMs can be adjusted without rebooting; Windows 2003 requires a reboot. With Linux it depends on kernel. CentOS 5 with kernel 2.6.18 can be resized; CentOS 6 and Ubuntu cannot. To adjust VM CPU & RAM resources:
If the VM template allows resize without reboot, the resize should be completed automatically and you will be returned to the VM details screen with a message indicating the resize was successful. If the template does not allow this, you will be asked to confirm that the VM will be rebooted so that the resize can take place. | |
