[libvirt] [PATCH] Remove pointless check for !ret in virDomainNetDefCoalesceParseXML
by Martin Kletzander
It was left there after removing a macro it was part of in first
version or so. Now it will always be NULL.

[libvirt] [PATCH v2 0/3] Add support for coalesce settings on interfaces
by Martin Kletzander
In linux this is supported since 4.11-rc3, I tested it with
4.11.0-rc5-next-20170407. The particular patch can be found
here:
https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git/commit...
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1414627
In this version the XML is different so that there are no underscores
(and it's actually more readable, IMHO).
Plus some minor adjustments needed after rebase.

You can see for yourself - just fire up wireshark with libvirt dissector
installed and issue the API.
Also, you may look at remote_typed_param_value and remote_typed_param
structs defined in src/remote/remote_protocol.h.

Man page for getifaddrs also states that the "ifa_addr" may contain
a null pointer which happens if there is an existing network interface
on the host without IP address.

[libvirt] [PATCH] Use port range 5901-5999 if not set in qemu.conf, avoid port 5900
by Christophe de Dinechin
In order to avoid conflict with the default port (5900) for host VNC server
(vino-server for example), or to conflict with X11 (starting at port 6000),
restrict range of ports to 5901-5999 unless explicitly specified in qemu.conf.
On the other hand, if port range is explicitly specified in qemu.conf,
there is no reason not to allow ports 1024-5900 (system ports are below 1024).
