Hello Mukesh, I've applied the following patch to the Linux kernel and recompiled, and now features in elf note seems to be complete (as reported by xl): xc: detail: elf_xen_parse_note: FEATURES = "!writable_page_tables|pae_pgdir_above_4gb|writable_descriptor_tables|auto_translated_physmap|supervisor_mode_kernel|hvm_callback_vector" But still the domain boots in PV mode. I've attached the output of 'xl -vvv create config.cfg' and dmesg. I think I've got all the hypervisor/tools patches applied correctly, but I will check again tomorrow morning in case I'm missing something. xl -vvv create config.cfg: Parsing config from pvh.cfg
