Actually I'm testing libvirt-0.10.2.1-2.fc18.x86_64 & libvirt from git, and seeing roughly the same set of problems with both. Didn't try 1.0.0 at all. To use libvirt from git, I'm doing: killall libvirtd lt-libvirtd ~/d/libvirt/run ./test-parallel Plus I should note a few things about my environment: - Fedora 18 - 16 GB of RAM (if you don't have that, reduce NR_THREADS in the test) - baremetal with KVM on a very fast Intel Sandybridge (I doubt this is reproducible in a VM) - I've configured core_pattern and ulimit to capture coredumps in /tmp
