      I just recently created a new "Golden Template" of AlamLinux, i noticed AlmaLinux 9 used BIOS in the XO provided Template however Rocky Linux 9 uses UEFI. Is there any particular reason for this? Is there a performance difference between either? I'm wondering if i need to start over and select the Rocky Template if UEFI does perform better. I also notice Ubuntu uses UEFI but Debian uses BIOS however i also understand there is much more of a difference there.

          @flakpyro From my experience, VM with UEFI boots faster than BIOS. For some OS versions UEFI runs faster IF there are no Xen drivers. But for most installs it does not matter much, except for Debian... which has given me problems with pool/migration/reboot with the UEFI installs on XCP (there's a workaround).

          So, I would vote for UEFI as the default for all OS/VMs that support it correctly since most are moving to that anyway (including XCP hosts).
