Remove non-existent symbols from the version script
The Solaris linker rightfully complains if a non-existent symbol is
referenced. Since these symbols don't exist in the current source, they
can have no purpose in a version script, so remove them.

[libvirt] virsh save produces "unknown migration protocol: stdio"
by Richard W.M. Jones
I just want to forward this comment on from #virt so that we don't
lose it. It appears to be an incompatibility between libvirt 0.5.0
and recent KVM.
<knowinters> Hi, I'm using libvirt 0.5.0 with kvm-79, when I do virsh
save kvm replies with "unknown migration protocol: stdio". A state
file is created, but it's only 4K and when restored the vm boots from
scratch instead of starting where it was when i saved. I googled but
couldn't find a resolution. Is this a known issue?
<knowinters> nm i think i see what's happening.. it
<knowinters> 's using the exec: migration method to call dd to move
the state from stdio to a file
<knowinters> exec: isn't in kvm-79 i don't think, but i see it in git
so ill try that
Rich.

[libvirt] PATCH: Fix deadlock upon config file reload
by Daniel P. Berrange
Turned out there was a small locking bug when reloading domain config
files after SIGHUP. I committed the following patch to add in the missing
unlock call. This was one of the files I'm unable to do static analysis
on, hence why it was missed.

[libvirt] [PATCH] remove redundant optname arguments
by Jim Meyering
>From a5c76721c22cf51b47059a91317f87a9f47c6868 Mon Sep 17 00:00:00 2001
From: Jim Meyering <meyering(a)redhat.com>
Date: Tue, 9 Dec 2008 22:22:08 +0100
Subject: [PATCH] remove redundant optname arguments
This is the second part of the change mentioned here:
http://thread.gmane.org/gmane.comp.emulators.libvirt/10331
It removes the essentially redundant "optname" parameter
from each of the vshCommandOptNetworkBy and vshCommandOptDomainBy
functions as well as the correspond macros (without "By" suffix).
Now, instead of always passing the optname, "domain", to
vshCommandOptDomainBy, that function requires that its command
argument refer to an opts array containing a "domain" option.
This normalization makes one more help-related change:
it renames the net-start "name" argument to the more
sensible and consistent "network".
* src/virsh.c (VSH_BYNAME, vshCommandOptDomain)
(cmd_has_option): New function, used in vshCommandOptDomainBy
and vshCommandOptNetworkBy.
(vshCommandOptDomainBy, vshCommandOptNetworkBy): Remove the optname
parameter, it's always "domain" ("network"). Update all callers.
Call cmd_has_option.

* src/Makefile.am (virsh-pool-edit.c): This code is generated
from cmdEdit, and cmdEdit uses the vshCommandOptDomain macro which
now, with the changes above, has only 3 (was 4) arguments, yet the
macro use is mapped to vshCommandOptPool, which still requires 4
arguments. So this change adjusts the sed code to reinsert the
just-removed argument -- we're not changing pool-related code right
now, because it's not as straight-forward.
