FWIW, a test report from an end user. I used the following for testing, which is derived from the instructions Juergen provided earlier this year. Maybe it's useful for someone else who wants to test. git clone https://git.savannah.gnu.org/git/grub.git git checkout -b xen_pvh [apply patches from emails] ./autogen.sh rm -rf knorrie/build mkdir -p knorrie/build cd knorrie/build ../../configure TARGET_LDFLAGS=-static --target=i386 --with-platform=xen_pvh make I just symlinked the test-kernel to vmlinuz-pvh here, so that I could easily boot back into the regular kernel with pvgrub2, which is hardcoded to look at /vmlinuz in my case (no grub with menu in the domU etc). cat
[Xen-devel] [PATCH v3 00/18] xen: add pvh guest support
This patch series adds support for booting Linux as PVH guest. Similar to i386/xen and x86_64/xen platforms the new i386/xenpvh platform grub is booted as a standalone image directly by Xen. For booting Linux kernel it is using the standard linux kernel loader. The only modification of the linux loader is to pass the ACPI RSDP address via boot parameters to the kernel, as that table might not be located at the usual physical address just below 1MB. The related Linux kernel patches have been accepted in the merge window for post 4.19 (4.20 or 5.0, whatever it will be called). Changes in V3: - addressed lots of comments, most by Daniel and some by Roger, details are mentioned in the individual patches Changes in V2: - extend linux boot protocol version 2.14 to report back the protocol version supported by grub2 (needed as there are grub2 downstream variants in some distros which clobber data after the setup_header) - split former patch 4 into 10 patches - fix memmap handling for >4GB of memory - added new patch from Hans (thanks for that one) - addressed most of Daniel's comments (see individual patches) Hans van Kranenburg (1): grub-module-verifier: Ignore all_video for xenpvh Juergen Gross (17): xen: add some xen headers loader/linux: support passing rsdp address via boot params xen: carve out grant tab initialization into dedicated function xen: prepare common code for Xen PVH support xen: add some dummy headers for PVH mode xen: rearrange xen/init.c to prepare it for Xen PVH mode xen: add PVH specific defines to offset.h xen: add basic hooks for PVH in current code xen: add PVH boot entry code xen: setup hypercall page for PVH xen: get memory map from hypervisor for PVH xen: setup Xen specific data for PVH xen: init memory regions for PVH xen_pvh: add build runes for grub-core xen_pvh: support building a standalone image xen_pvh: support grub-install for xen_pvh xen_pvh: add support to configure configure.ac | 3 + gentpl.py | 4 +- grub-core/Makefile.am | 12 + grub-core/Makefile.core.def | 35 ++ grub-core/kern/i386/tsc.c | 2 +- grub-core/kern/i386/xen/pvh.c | 340 + grub-core/kern/i386/xen/startup_pvh.S | 81 + grub-core/kern/xen/init.c | 101 -- grub-core/loader/i386/linux.c | 9 + grub-core/mmap/i386/pc/mmap.c | 7 - include/grub/i386/linux.h | 5 +- include/grub/i386/memory.h| 7 + include/grub/i386/pc/int.h| 36 +- include/grub/i386/pc/int_types.h | 59 +++ include/grub/i386/tsc.h | 2 +- include/grub/i386/xen/hypercall.h | 5 +- include/grub/i386/xen_pvh/boot.h | 1 + include/grub/i386/xen_pvh/console.h | 1 + include/grub/i386/xen_pvh/int.h | 1 + include/grub/i386/xen_pvh/kernel.h| 30 ++ include/grub/i386/xen_pvh/memory.h| 1 + include/grub/i386/xen_pvh/time.h | 1 + include/grub/kernel.h | 4 +- include/grub/offsets.h| 21 +- include/grub/util/install.h | 1 + include/grub/util/mkimage.h | 3 +- include/grub/xen.h| 6 + include/xen/hvm/hvm_op.h | 296 +++ include/xen/hvm/params.h | 284 +++ include/xen/hvm/start_info.h | 98 + include/xen/memory.h | 665 ++ include/xen/physdev.h | 387 include/xen/trace.h | 339 + include/xen/xen.h | 104 -- util/grub-install-common.c| 1 + util/grub-install.c | 7 + util/grub-mkimage32.c | 4 +- util/grub-mkimage64.c | 4 +- util/grub-mkimagexx.c | 58 ++- util/grub-module-verifier.c | 1 + util/mkimage.c| 23 +- 41 files changed, 2906 insertions(+), 143 deletions(-) create mode 100644 grub-core/kern/i386/xen/pvh.c create mode 100644 grub-core/kern/i386/xen/startup_pvh.S create mode 100644 include/grub/i386/pc/int_types.h create mode 100644 include/grub/i386/xen_pvh/boot.h create mode 100644 include/grub/i386/xen_pvh/console.h create mode 100644 include/grub/i386/xen_pvh/int.h create mode 100644 include/grub/i386/xen_pvh/kernel.h create mode 100644 include/grub/i386/xen_pvh/memory.h create mode 100644 include/grub/i386/xen_pvh/time.h create mode 100644 include/xen/hvm/hvm_op.h create mode 100644 include/xen/hvm/params.h create mode 100644 include/xen/hvm/start_info.h create mode 100644 include/xen/memory.h create mode 100644 include/xen/physdev.h create mode 100644 include/xen/trace.h -- 2.16.4 ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject
