[libvirt-users] libvirtd using 11GB
Hi All, Am new to this list, and have asked in #ovirt / ovirt-users list and they pointed me to here ... I've seen libvirtd using ~11 GB of resident memory after the host has been running for about 60+ days with about 40 VMs running on it. The versions I'm currently running are : libvirt.x86_64 0.9.10-21.el6_3.7 libvirt-client.x86_64 0.9.10-21.el6_3.7 libvirt-lock-sanlock.x86_64 libvirt-python.x86_64 0.9.10-21.el6_3.7 I know I can just restart libvirtd and "all should be fine" (and hopefully I'll regain the 11GB of memory) - however, is there an updated version that maybe fixes a memory leak ??

Yes. John Ferlan did a great job in hunting memory leaks down. Most of his fixes went to 1.0.3, some into 1.0.4 or even 1.0.2. Michal
Ah great, thanks! Alex On 16 April 2013 09:55, Michal Privoznik <mprivozn@redhat.com> wrote:

In general, it can be a bit difficult to determine the exact commit which fixes problem you are seeing, because it depends on you concrete use case. However, you can try running libvirtd with valgrind and see where libvirtd leaks the most. This as disadvantage of libvirtd running a bit slower but on the other hand, if it is such huge leak even a little while should do. Maybe you will discover a new leak :) Michal

Can you run under valgrind to catch the root cause of the leak? Or can you update to prove the leak was fixed? Michal

The memory leak issue have been fixed on libvirt-0.10.2-18.el6_4.4. The libvirtd is still using ~13M of resident memory after the host has been running for about +10 days with about 20 VMs running on it. Before, I used libvirtd which version is 0.9.10-21.el6_3.7 on the same environment( days and vms),the libvirtd was using ~1.5G of resident memory.
