      Hi,

      I read this article on the performance increase HVM has on PV:
      https://xen-orchestra.com/blog/debian-pvhvm-vs-pv/

      Yeah, I know, we're almost 7 years further ๐Ÿ˜‰

      Anyway, as the xcp-ng center and XO these days has a button to simply switch between PV and HVM and back, I was wondering if on my Debian 7.11 and Debian 8.11 PV VMs, switching to HVM is as simple as clicking the button and rebooting.

      Well.. it seems to work. The output of Dmsg looks OK. Ethtool shows that the VM is now using HVM
      As suggested to check here: https://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers

      So, I suppose my question is simple:
      If I switch Debian 7 or 8 to HVM, is there anything else I should do?

        No, it's pretty simple. As long as you have a bootloader in your disk, that's fine.
