Use ./configure --prefix /path/to/somewhere if the default didn't match your expectations (the file libvirt/libvirt.spec.in shows the various configure options used when building for RHEL). It should be possible to use your own libvirtd in /usr/local regardless of whether the system-provided version is present and running, since the two installations should pick different path locations for pid files and other state information. But it also means that you can't (easily) use you libvirtd to run a VM created by the other libvirtd, without moving and possibly tweaking some configuration files. So maybe what you really wanted was to upgrade the system version of libvirtd. I think you can find add-on RPMs of newer libvirt versions built for RHEL, but they will not be part of RHEL 5.5 proper. Meanwhile, RHEL 6 will have a much newer version of libvirtd, if you are willing to wait for that. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
