I'm having no problems booting the installer and installing a Debian
11 guest in PVH mode, so I assume this must be HVM mode, which I
have not tried. That is with Xen 4.14.2 though.

4.11 is EOL now so neither Debian nor Xen is likely going to be able
to help you with that. You should try installing a more up to date
hypervisor version and trying again.

If it still happens with a supproted hypervisor version then Xen
devs are probably going to want to see debug output from dom0 and
domU, so booting dom0 with "log_lvl=all guest_loglvl=all" on the
hypervisor command line and starting with "xl -v create -f
guest.cfg" would be a good idea.

Cheers,
Andy
