[libvirt] newer libvirt version issues

[Franky Van Liedekerke]

Hi,

since we're running more than 20 hosts per KVM server, we needed to 
update libvirt to at least 1.1.2 for virtlockd to be able to cope with 
this (due to an old hardcoded limit that was in there before).
But where 1.1.0 compiles and runs just fine on a fully-patched CentOS 
6.4 server, newer version have all kinds of issues:

Every version of libvirt >= 1.1.2 crashes with a segfault on up-to-date 
CentOS 6.4 servers (see below).
Also, versions of libvirt >= 1.1.3 need a change in the spec file to be 
able to compile:
apparently the %doc entries that are different with 1.1.2 prevent 
rpmbuild to succeed on
CentOS servers. Using the %doc lines as per the 1.1.2 spec file results 
in a working rpmbuild.
The 1.1.4 version has issues with a symbol not found after compiling 
and letting it run:

error : virDriverLoadModule:78 : failed to load module 
/usr/lib64/libvirt/connection-driver/libvirt_driver_network.so 
/usr/lib64/libvirt/connection-driver/libvirt_driver_network.so:

And every time libvirt segfaults, there's this in the logs:
debug : virJSONValueToString:1133 : 
result={"id":"libvirt-6","error":{"class":"CommandNotFound","desc":"The 
command qom-list has not been found","data":{"name":"qom-list"}}}

9479: error : qemuMonitorJSONCheckError:352 : internal error: unable to 
execute QEMU command 'qom-list': The command qom-list has not been found

Any insights on any of these issues?
