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

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?
