Disclaimer done, lets start to play: To enable nested virtualization, go to the XenServer console (e.g. in XenCenter) and find out the UUID of the VM you want to permit being a virtualization host:<\/p>\n
# xe vm-list<\/pre>\nGo through the list and remember the first characters of your VM\u00b4s UUID. After making sure the VM is powered down,\u00a0turn on nested hardware virtualization. Enter your VM\u2019s UUID instead of <UUID>. After typing the first characters, you can hit TAB to auto-complete:<\/p>\n
# xe vm-param-set uuid=<UUID> platform:exp-nested-hvm=true<\/pre>\nBoot the VM and check if the virtual processor reports hardware virtualization\u00a0(\u201cvmx\u201d) capabilities. In Linux this might look like this:<\/p>\n
