[libvirt] How to pass -no-kvm-irqchip to KVM/QEMU guests
by Brody Wong 09 Apr '14

09 Apr '14

Hi, experts, I am using libvirt 0.10.2, and doing some tests against guest IO performance. Can I have a way to pass -no-kvm-irqchip in libvirt xml files to qemu-kvm? I did some search in google, it hits: http://www.redhat.com/archives/libvir-list/2009-September/msg00495.html But it seems it does not work on CentOS, after I used this wrapper script, qemu-kvm will crash.. and I did not find libvirt upstream solved this problem, is there anther way to solve this? Thanks a lot.

[libvirt] [PATCH] LXC: Fix return code evaulation in lxcCheckNetNsSupport()
by Richard Weinberger 08 Apr '14

08 Apr '14

Commit b9dd878f (util: make it easier to grab only regular command exit) changed the call semantics of virCommandRun() and therefore of virRun() too. But lxcCheckNetNsSupport() was not updated.

[libvirt] [PATCH] Use a static initializer for static mutexes
by Daniel P. Berrange 08 Apr '14

Now that we ditched our custom pthread impl for Win32, we can use PTHREAD_MUTEX_INITIALIZER for static mutexes.
