[libvirt] [PATCH]util: Helper function for checking existence of hook files for specific driver
by Chen Hanxiao
From: Chen Hanxiao <chenhanxiao(a)cn.fujitsu.com>
We refresh the status of hook scripts
only when start/restart libvirt or reloads its configuration.
But hooks scripts may be changed.
This function will help to check its existence.
And we do not need to start/restart libvirt if
we add/remove hook files.

[libvirt] [PATCH v3 0/4] don't masquerade local broadcast/multicast packets
by Laszlo Ersek
Masquerading local broadcast breaks DHCP replies for some clients.
There has been a report about broken local multicast too.
(See references in the patches.)
Regarding multicast, right now the series disables masquerading for the
most restrictive local multicast range only.
v2->v3 changes:
- Rename iptables(Add|Remove)ForwardDontMasquerade to
iptables(Add|Remove)DontMasquerade [Laine].
- Pass (address, prefix) pairs as both source and destination parameters
to these functions.
- Introduce virPfxSocketAddr structure for simpler handling of said
(address, prefix) pairs.
- Also prevent masquerading of directed broadcast [Laine].
- Start to get serious about pointers-to-const.
Testing:
- "make check" and "make syntax-check" pass,
- thanks to the great docs on libvirt.org (compiling & deployment) I
even managed to test this on my RHEL-6 laptop, with repeated net-start
/ net-destroy commands.

Re: [libvirt] virDomainGetInfo() returns wrong domain state

Could you please help me with below query.

Subject: virDomainGetInfo() returns wrong domain state
Hi Team,
I have written below code to get the VM state at run time. I found, though the VM is in shut-off state, when I use the function virDomainGetInfo(); I get state as running. Could you please let me know what wrong I am doing. To know the actual VM state I used 'virsh list' and it clearly shows the VM is in shut-off state. Please find the log and code snippet below.
Log from virsh:
=================
[host:~]$ virsh list --all
Id Name State
----------------------------------------------------
1 calvados running
2 LCXR running
3 default-sdr--1 running
- test--2 shut off

Note : Here 1 is actually running.
Code snippet:

return state;
}
virDomainInfo res_util;

res = virDomainGetInfo(dom, &res_util);
vminfo[vm_idx].vm_state =

[libvirt] [PATCH] maint: update to latest gnulib

Since we're about to freeze, it's time to pick up the latest
upstream gnulib. Among other changes, gnulib now guarantees the
use of some -f flags that we were previously manually adding.
* .gnulib: Update to latest, in part for warning improvements.
* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Drop
flags that are now guaranteed by gnulib.
* bootstrap: Resync to gnulib.
