The libvirtd daemon has some arbitrary logic to drop privileges, but
only on Solaris platforms. This was added during Xen days, when Xen was
the only driver running in libvirtd. There's no expectation or testing
that this works with the new libxl stack, nor whether dropping
privileges breaks any of the secondary drivers. Finally, we'll be
splitting drivers out into their own independant daemons, so this won't
be applicable to libvirtd in future anyway.
The remote driver client meanwhile arbitrarily disables daemon
auto-spawn when connecting as non-root, breaking a key feature of
libvirt unprivileged connections.
Since we've not had any contributions for Solaris since circa 2012
and we don't do any CI testing we should consider this platform
unmaintained and thus reasonable to remove this cruft. If someone steps
forward to maintain Solaris again, this code would need re-evaluating to
come up with something more targetted.
There's various __sun conditionals in the Xen driver code, but those are
not touched. This is all for the legacy Xen driver, which will be
entirely removed at some point in future, so not benefit to hacking out
just the Solaris parts.

The global log buffer feature was deleted in:
commit c0c8c1d7bb
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Mon Mar 3 14:54:33 2014 +0000
Remove global log buffer feature entirely
A earlier commit changed the global log buffer so that it only
records messages that are explicitly requested via the log
filters setting. This removes the performance burden, and
improves the signal/noise ratio for messages in the global
buffer. At the same time though, it is somewhat pointless, since
all the recorded log messages are already going to be sent to an
explicit log output like syslog, stderr or the journal. The
global log buffer is thus just duplicating this data on stderr
upon crash.
The log_buffer_size config parameter is left in the augeas
lens to prevent breakage for users on upgrade. It is however
completely ignored hereafter.

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.
