Hi All,
I'm excited (and a bit nervous) to finally submit xen PVH patches for
your input. This is Phase I. Kindly ignore the 'noinline' for now, it
helps me debug. Of course, in the final patches that won't be there.
Phase I:
- Establish a baseline of something working. These patches allow for
dom0 to be booted in PVH mode, and after that guests to be started
in PV, PVH, and HVM modes. I also tested booting dom0 in PV mode, and
starting PV, PVH, and HVM guests.
There are few fixme's that I thought we could punt to Phase II.
Also, the disk must be specified as phy: in vm.cfg file:
> losetup /dev/loop1 guest.img
> vm.cfg file: disk = ['phy:/dev/loop1,xvda,w']
I've not tested anything else.
Phase II:
- Shutdown cleanup. I need to look at shutdown path during dom0 reboot.
- arch_get_info_guest() and other fixmes.
- Change xl to support other modes other than "phy:".
Phase III:
- Migration, shadow code. I've skipped shadow code for now.
Thanks for all the help,
Mukesh

Hi Mukesh, I would like to give a try to PVH, but I'm having some failures while applying the patches, could you tell me the base commit on top of which I should apply this series?

Hi Roger, I realized over the weekend I forgot to include the c/s number. It's 26124. I'll be refreshing my tree again over the next few days while the patches are being reviewed.

I've also fetched branch stable/pvh.v7 from Konrad's Linux tree, enabled the CONFIG_XEN_X86_PVH option and compiled the Linux kernel, but I'm unable to get the kernel to run in PVH mode, it defaults to PV mode, do I need to use a PVH Dom0 in order to create PVH guests?

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

Hmm.. err code 7 is : "7 VM entry with invalid control field(s)", So we need to see what control fields are in the VMCS. Can you please add to : vm_launch_fail(): void vm_launch_fail(void) { unsigned long error = __vmread(VM_INSTRUCTION_ERROR); printk("<vm_launch_fail> error code %lx\n", error); vmcs_dump_vcpu(current); ... } Just for ease, please boot with one cpu and one vcpu. Also, can you please compile xen with debug=n and try also. I'm also trying on different machine here as I type this.
