A few more that I know of:

- EFI
- user mode accessible PV clock
- runtime microcode loading
- support for running with more than 1Tb (XEN_ELFNOTE_INIT_P2M)
  (but afaict there are also shortcomings needing fixing in the tools
  when going beyond 512Gb)
- support for using huge initrd (XEN_ELFNOTE_MOD_START_PFN)
- blktap (or a suitable replacement thereof)
- pvSCSI
- pvUSB
- perf/oprof

Plus various smaller items where e.g. certain special drivers need
adjustments to work right in dom0 (dcdbas, dell_rbu, coretemp,
via-cputemp, msr).

Also I'm not certain whether the MSI-X issue that was found a while
ago is meanwhile fully fixed.
