25456e0470 tests: reintroduce tests for libxl's legacy nested setting
The preferred location for setting the nested CPU flag changed in
Xen 4.10 and is advertised via the LIBXL_HAVE_BUILDINFO_NESTED_HVM
define.  Commit 95d19cd0 changed libxl to use the new preferred
location but unconditionally changed the tests, causing 'make check'
failures against Xen < 4.10 that do not contain the new location.

Commit e94415d5 fixed the failures by only running the tests when
LIBXL_HAVE_BUILDINFO_NESTED_HVM is defined. Since libvirt supports
several versions of Xen that use the old nested location, it is
prudent to test the flag is set correctly. This patch reintroduces
the tests for the legacy location of the nested setting.

95d19cd015 libxl: prefer new location of nested_hvm in libxl_domain_build_info
If available, use b_info->nested_hvm instead of
b_info->u.hvm.nested_hvm. This will make nested HVM config available
also for PVH domains.

d4a8fa0cd1 libxl: set shadow memory for any guest type, not only HVM
Otherwise starting PVH guest will result in "arch_setup_bootlate:
mapping shared_info failed (pfn=..., rc=-1, errno: 12): Internal error".

After this change the behavior is the same as in `xl`.

83edaf4435 libxl: don't hardcode scheduler weight
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.

Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.

Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.

c391e07eb0 libxl: add support for specifying clock offset and adjustment
libxl supports setting the domain real time clock to local time or
UTC via the localtime field of libxl_domain_build_info. Adjustment
of the clock is also supported via the rtc_timeoffset field. The
libvirt libxl driver has never supported these settings, instead
relying on libxl's default of a UTC real time clock with adjustment
set to 0.

There is at least one user that would like the ability to change
the defaults

https://www.redhat.com/archives/libvirt-users/2018-February/msg00059.html

Add support for specifying a local time clock and for specifying an
adjustment for both local time and UTC clocks. Add a test case to
verify the XML to libxl_domain_config conversion.

Local time clock and clock adjustment is already supported by the
XML <-> xl.cfg converter. What is missing is an explicit test for
the conversion. There are plenty of existing tests that all use UTC
with 0 adjustment. Hijack test-fullvirt-tsc-timer to test a local
time clock with 1 hour adjustment.

d8e8b63d30 libxl: Add a test suite for libxl_domain_config generator
The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.

Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.
