Thanks for the reproducer program, that should make life much easier.
Just to confirm, you're seeing these problems on both 1.0.0 and
current GIT master ?
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
