[PATCHv2 0/2] ch: minor fixes - segfault and last meaningful error preservation
by Kirill Shchetiniuk
During fixing some other issue found out a few minor bugs
related to CH driver.
First bug is related to monitor object ref count
in virCHStartEventHandler and virCHEventHandlerLoop, as
object was unrefed by parent while is still used by child
thread. Moved object unref to the correct place to the
correct thread.
Second bug is related to v object ref count in
virCHStartEventHandler, as vm object was unrefed,
while is still used later, move object unref to
after its last usage.
Third bug is related to error handling and
propagation. Last meaninful error was reset
by virCHProcessStop, which have led to
unknown error message in virsh. Add error
preservation at the begining of the function
and restoring it at the end to keep
consistent error output
Kirill Shchetiniuk (2):
ch: virCHProcessStop preserve last meaningful error

[PATCH] docs: remove references to removed APIs
by Daniel P. Berrangé
The glib adoption docs was suggesting avoidance of certain APIs that
were obsoleted by glib, during the transition period. Now that the
referenced APIs no longer exist in libvirt code, they can also be
removed from the docs.
NB, the virStringListRemoveDuplicates method remains since there is
no glib equivalent.

[PATCH] scripts: add execute permission to several files
by Daniel P. Berrangé
From: Daniel P. Berrangé <berrange(a)redhat.com>
Most, but not all, files in scripts have execute permission. While we
don't need this in order to launch them via meson/ninja build rules,
it is nice to direct execution if they have execution permission. This
makes the practice consistent across all scripts.

Fwd: system cache dropped
by matus valentin
Hi,
I have a setup with multiple virtual machines (VMs) running on one host,
each with a saved state. All VMs share the same parent, which is located on
a shared drive. Whenever I restore any VM using virsh restore, the parent
is dropped from the system cache, causing all data to be downloaded from
the shared drive again. This results in unnecessary network traffic, even
though the parent changes very rarely. However, if I create a child from
the parent and call virsh create to create a new VM, the parent is never
dropped from the system cache.
Is this expected behavior? Should the parent be retained in the system
cache during a virsh restore operation? Are there any configurations or
settings that can prevent the parent from being dropped from the cache?
thanks
