[libvirt] [PATCH] Revert "virsh: Increase device-detach intelligence"
by Osier Yang
This reverts commit ea7182c29f185e7c1527b10fbe16dc4ba1f45a88.
Conflicts are resolved.
This is a temporary reverting for it introduces regression of device
detaching (any device XML doesn't uses the same order as libvirt
generates, or has uses decimal for some attrs (e.g. "slot") will
cause the failure, as virsh compares the XML simply earlier before internal
parsing). We could take the patch back when the new API for normalizing
XML is ready.

[libvirt] [PATCH] nwfilter: fix typing error in filter
by Stefan Berger
Fix a typing error in the no-ip-spoofing filter.
Return DHCP request packets passing through this filter. Have
the user use another filter to actually allow DHCP requests to be
sent (action='accept').

[libvirt] blockJob events broken
by Adam Litke
Hi Dan,
I noticed that since d09f6ba5feb655925175dc80122ca2a1e14db2b9, blockJob events
are not being delivered to registered clients. I did verify that VM lifecycle
events are still working fine though. I am confused why your patch has only
affected my blockJob events. Do you have any ideas?

[libvirt] [PATCH] virsh: Two new fields for command domblklist
by Osier Yang
Disk "type" and "device" are generally interesting stuffs the
user who wants to known too. Though it's likely breaks the script
which parses the command output by field (e.g. awk), putting
them in the head is better, as it coheres with the user's habit
more. (Trying to find the small word (type, device) after a
very long file path (could be) sounds not a good idea).

[libvirt] [PATCH 1/1] Added check for maximum number of vcpus exceeding topology limit
by Martin Kletzander
Earlier, when the number of vcpus was greater than the topology allowed,
libvirt didn't raise an error and continued, resulting in running qemu
with parameters making no sense. Even though qemu did not report any
error itself, the number of vcpus was set to maximum allowed by the
topology.

[libvirt] [PATCH] build: fix build on mingw with netcf available
by Eric Blake
The autobuilder pointed out an odd failure on mingw:
../../src/interface/netcf_driver.c:644:5: error: unknown field 'close_used_without_including_unistd_h' specified in initializer
cc1: warnings being treated as errors
This is because the gnulib headers #define close in order to work
around some odd mingw problems with close(), but it happens to
also affect field members declared with a name of struct foo.close.
As long as the same headers are included for the definition and use
of the struct, the #define doesn't matter, but the netcf file hit
an instance where things were in a different order. Fix this for
all clients that use a struct member named 'close'.
* src/driver.h: Include <unistd.h> before using 'close'.
---
I don't have netcf for mingw locally, so I'd like a review before
pushing this, since I couldn't confirm whether it fixed the
broken build on the autobuilder.

[libvirt] [PATCH] Disable netcf if building without libvirtd
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Although the netcf interface driver can in theory be used by
the stateless drivers, in practice none of them want to use
it because they have different ways of dealing with interfaces.
Furthermore, if you have mingw32-netcf installed, then the
libvirt mingw32 build will fail with
../../src/interface/netcf_driver.c:644:5: error: unknown field 'close_used_without_including_unistd_h' specified in initializer
