This is a respin of my old PVHv1 patch[1], converted to PVHv2. The actual code
use "PVH" name.
It introduce new guest ostype VIR_DOMAIN_OSTYPE_XENPVH, and also PVH machine,
machine="xenpvh" attribute is used.
Since PVHv2 relies on features in newer Xen versions, I needed to convert also
some older code. For example b_info->u.hvm.nested_hvm was deprecated in favor
of b_info->nested_hvm. While the code do handle both old and new versions
(obviously refusing PVHv2 if Xen is too old), this isn't the case for tests.
How it should be handled, if at all?
To test this with all supported Xen versions (4.6, 4.7, 4.8, 4.9, 4.10, 4.11,
unstable), I've extended travis configuration for that[2]. It isn't exactly
trivial to build Xen 4.6-4.8 on recent system, mostly thanks to -Werror and new
warnings, but also other toolchain changes. Because of this, the configuration
is rather hacky. But it may be a good idea to include multiple pre-built Xen
versions in the base docker image and choose one using ./configure options (maybe
together with some symlink or environment variable like PKG_CONFIG_PATH).

Changes in v2:
- drop "docs: don't refer to deprecated 'linux' ostype in example"
patch -
migrating further away from "linux" os type is offtopic to this series and
apparently is a controversial thing
- drop "docs: update domain schema for machine attribute" patch -
already applied
- apply review comments from Jim
- rebase on master
Changes in v3:
- rebase on master, drop already applied patches
- use #ifdef LIBXL_DOMAIN_TYPE_PVH to detect PVH support, fix compilation
failure on older Xen
- exclude PVH from VIR_DOMAIN_OSTYPE_XEN <-> VIR_DOMAIN_OSTYPE_LINUX conversion
- fix reported capabilities for PVH
Changes in v4:
- change PVH support detection method
Changes in v5:
- use VIR_DOMAIN_OSTYPE_XENPVH
- add news entry

New subject: [libvirt] [PATCH v5 2/6] libxl: add support for PVH
Since this is something between PV and HVM, it makes sense to put the
setting in place where domain type is specified.
To enable it, use <os><type
machine="xenpvh">...</type></os>. It is
also included in capabilities.xml, for every supported HVM guest type - it
doesn't seems to be any other requirement (besides new enough Xen).

Changes in v2 proposed by Jim:
- use new_arch_added var instead of i == nr_guest_archs for clarity
- improve comment
- adjust for now required Xen >= 4.6 (remove part for Xen < 4.5)
Changes in v3:
- limit VIR_DOMAIN_OSTYPE_XEN -> VIR_DOMAIN_OSTYPE_LINUX conversion to
Xen PV only
- do not accept VIR_DOMAIN_OSTYPE_LINUX for PVH
- fix reported capabilities for PVH - remove hostdev passthrough and
video/graphics
- use #ifdef LIBXL_DOMAIN_TYPE_PVH instead of hypervisor version to
check for PVH support
- compile fix for Xen < 4.9
Changes in v4:
- revert to "i == nr_guest_archs-1" check
- let configure check for LIBXL_DOMAIN_TYPE_PVH and use #ifdef
HAVE_XEN_PVH then
- fix comment about Xen version
Changes in v5:
- use 'xenpvh' os type

New subject: [libvirt] [PATCH v5 4/6] xenconfig: add support for parsing type= xl config entry
builder="hvm" is deprecated since Xen 4.10, new syntax is type="hvm"
(or
type="pv", which is default). Since the old one is still supported,
still use it when writing native config, so the config will work on
older Xen too (and will also not complicate tests).
Signed-off-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com>
---
"type" option is the only syntax for specifying PVH guest, coming in
next patch.
Changes in v2:
- fix code style

Hi Marek,
Thanks for all of the work! I've pushed this series, just in time for the 4.10.0
freeze :-). Please keep an eye out for any Coverity fallout (or anything else we
may have missed) that needs fixed before the release.
Regards,
Jim

This is a respin of my old PVHv1 patch[1], converted to PVHv2. The
actual code
use "PVH" name.
It introduce new guest ostype VIR_DOMAIN_OSTYPE_XENPVH, and also PVH machine,
machine="xenpvh" attribute is used.
Since PVHv2 relies on features in newer Xen versions, I needed to convert also
some older code. For example b_info->u.hvm.nested_hvm was deprecated in favor
of b_info->nested_hvm. While the code do handle both old and new versions
(obviously refusing PVHv2 if Xen is too old), this isn't the case for tests.
How it should be handled, if at all?
To test this with all supported Xen versions (4.6, 4.7, 4.8, 4.9, 4.10, 4.11,
unstable), I've extended travis configuration for that[2]. It isn't exactly
trivial to build Xen 4.6-4.8 on recent system, mostly thanks to -Werror and new
warnings, but also other toolchain changes. Because of this, the configuration
is rather hacky. But it may be a good idea to include multiple pre-built Xen
versions in the base docker image and choose one using ./configure options (maybe
together with some symlink or environment variable like PKG_CONFIG_PATH).

Changes in v2:
- drop "docs: don't refer to deprecated 'linux' ostype in
example" patch -
migrating further away from "linux" os type is offtopic to this series and
apparently is a controversial thing
- drop "docs: update domain schema for machine attribute" patch -
already applied
- apply review comments from Jim
- rebase on master
Changes in v3:
- rebase on master, drop already applied patches
- use #ifdef LIBXL_DOMAIN_TYPE_PVH to detect PVH support, fix compilation
failure on older Xen
- exclude PVH from VIR_DOMAIN_OSTYPE_XEN <-> VIR_DOMAIN_OSTYPE_LINUX conversion
- fix reported capabilities for PVH
Changes in v4:
- change PVH support detection method
Changes in v5:
- use VIR_DOMAIN_OSTYPE_XENPVH
- add news entry
Marek Marczykowski-Górecki (6):
libxl: reorder libxlMakeDomBuildInfo for upcoming PVH support
libxl: add support for PVH
tests: add basic Xen PVH test
xenconfig: add support for parsing type= xl config entry
xenconfig: add support for type="pvh"
