[libvirt] [PATCH] qemu: Introduce qemuDomainDefCheckABIStability
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=994364
Whenever we check for ABI stability, we have new xml (e.g. provided by
user, or obtained from snapshot, whatever) which we compare to old xml
and see if ABI won't break. However, if the new xml was produced via
virDomainGetXMLDesc(..., VIR_DOMAIN_XML_MIGRATABLE) it lacks some
devices, e.g. 'pci-root' controller. Hence, the ABI stability check
fails even though it is stable. Moreover, we can't simply fix
virDomainDefCheckABIStability because removing the correct devices is
task for the driver. For instance, qemu driver wants to remove the usb
controller too, while LXC driver doesn't. That's why we need special
qemu wrapper over virDomainDefCheckABIStability which removes the
correct devices from domain XML, produces MIGRATABLE xml and calls the
check ABI stability function.

[libvirt] [PATCH] Move virNetDevVPort enum impl into virnetdevvportprofile.c
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The enum for virNetDevVPort is declared in the header file
virnetdevvportprofile.h, but for some reason the impl is
in netdev_vport_profile_conf.c.
This causes a dep from src/util onto src/conf which is not
allowed. Move the enum impl into virnetdevvportprofile.c
to break the circle.

[libvirt] [PATCH] AArch64: Porting of armv7l conditons to run qemu for aarch64.
by Pranavkumar Sawargaonkar
AArch64 qemu has similar behavior as armv7l, like use of mmio etc.
This patch adds similar bypass checks what we have for armv7l to aarch64.
E.g. we are enabling mmio transport for Nicdev.
Making addDefaultUSB and addDefaultMemballoon to false etc.

[libvirt] [PATCH] qemu: Init @pcidevs in qemuPrepareHostdevPCIDevices
by Michal Privoznik
At the beginning of the function qemuPrepareHostdevPCICheckSupport() is
called. After that @pcidevs is initialized. However, if the very first
command fails, we go to 'cleanup' label where virObjectUnref(pcidevs) is
called. Obviously, it is called before @pcidevs was able to get
initialized. Compiler warns about it:

[libvirt] Can we make sc_copyright_check non-fatal?
by Cole Robinson
The copyright date syntax check is a source of frustration for me:
- It fails on old maint branches.
- It pokes into non git managed directories in $(srcdir). I like to keep
directories like f18-maint.git, f19-maint.git etc. that are checkouts of the
respective maint branches so I can parallelize when doing maint builds, and I
like to keep them in my libvirt.git dir for organization, but running
syntax-check in libvirt.git fails on the copyright check in
$(srcdir)/f18-maint.git/.gnulib/...
Is there any way to make it non-fatal? If it still spams with all the
'failures' I'm sure that's enough to encourage fixing the issues without
blocking valid usage.
Thanks,
Cole
