Ensuring hardware virtualization extensions are installed
Next, you'll want to ensure that hardware virtualization extensions are enabled on the intended Proxmox VE host.
Assuming there's no operating system on the machine, it's very simple to check this with a Ubuntu Desktop LiveCD. Follow these steps:
- Download the Ubuntu LiveCD image from http://www.ubuntu.com/download/desktop and burn it to a DVD.
- Boot the new machine from the Ubuntu LiveCD. (For more information on this process, visit https://help.ubuntu.com/community/LiveCD#How-To_LiveCD_Ubuntu.)
- Once the desktop is fully available, open the terminal emulator.
- For an Intel-based system, enter the following command in the terminal emulator:
egrep -c '(vmx|svm)' /proc/cpuinfo
.
If hardware virtualization extensions are enabled, as is the hope, this command should simply return an integer equal to the number of CPU cores in the machine. If the command returns a 0, hardware virtualization extensions must be enabled in the Intel system's EFI/BIOS...
