Hi, if i test the restore/destroy of an KVM/QEMU vm on the same system (fedora core 20 libvirtd 1.1.3.5), i can confirm what you say. there are no threads which are created and then not closed! so my problem/observation affects the interaction of libvirtd/xen. all the best max ----------------ursprüngliche Nachricht----------------- Von: "Jim Fehlig" jfehlig@suse.com An: ustermann78@web.de Kopie: libvir-list@redhat.com, libvirt-users@redhat.com Datum: Tue, 30 Sep 2014 18:44:17 -0600 -------------------------------------------------

hello,
if i start a transient guest doamin via "virsh create abcd.xml" i see an additional libvirt thread and also some open files:
pstree -h `pgrep libvirtd` libvirtd───11*[{libvirtd}]

if i destroy these vm via "virsh destroy abcd", i see that the additional thread still exists and also the list of openfiles is the same.
I don't see this behavior with current libvirt git master
# pstree `pgrep libvirtd` libvirtd───10*[{libvirtd}] # virsh create ./test.xml Domain test created from ./test.xml # pstree `pgrep libvirtd` libvirtd───11*[{libvirtd}] # virsh destroy test Domain test destroyed # pstree `pgrep libvirtd` libvirtd───10*[{libvirtd}]
All file descriptors opened when the domain was created were closed as well.
What version of libvirt are you using?
Regards, Jim
