i have this calls on stack

This is just probably a client waiting for the corresponding libvirtd to provide a reply message. Are you able to get libvirtd debug logs so we can see what's going on?

http://wiki.libvirt.org/page/DebugLogs

BTW, what's the libvirt version you are running?

Yuck, this is 1.0.6; Well, from the logs it seems like the daemon is stuck. Can you attach to the libvirtd while it's being stuck and run 't a a bt' and post the result? I wonder if we have a deadlock somewhere.

Michal

if i correctly understand you, you need debugger backtrace after libvirtd stuck ?, if so, here is bt from gdb (gdb) bt #0 0x00007f00c1ae876d in poll () from /lib64/libc.so.6 #1 0x00007f00c203cfcb in virEventPollRunOnce () from /usr/lib64/libvirt.so.0 #2 0x00007f00c203ba4d in virEventRunDefaultImpl () from /usr/lib64/libvirt.so.0 #3 0x00007f00c214a5cd in virNetServerRun () from /usr/lib64/libvirt.so.0 #4 0x00007f00c2aea08a in main () also maybe build options means..., here is my build options * app-emulation/libvirt ::gentoo 1.0.3-r2 1.0.5.1-r3 1.0.5.2(~) 1.0.6(~)* (9999)K {:0} ::installed 1.0.6 {:0} app-emulation/libvirt-1.0.6:0::installed (world) Description C toolkit to manipulate virtual machines Homepage http://www.libvirt.org/ From repositories gentoo Installed time Tue Jun 18 07:18:08 EEST 2013 Installed using paludis-1.4.0 License LGPL-2.1 Use flags USE (-audit) (-avahi) (caps) (-firewalld) (fuse) (iscsi) (libvirtd) (lvm) (-lxc) (macvtap) (nfs) (nls) (-numa) (-openvz) (-parted) (pcap) (-phyp) (policykit) (python) (qemu) (-rbd) (sasl) (-selinux) (-systemd) (udev) (-uml) (vepa) (-virt-network) (virtualbox) (-xen) python_single_target (-python2_5) (-python2_6) (python2_7) python_targets (-python2_5) (-python2_6) (python2_7) Build Options -trace Trace actions executed by the package (very noisy, for debugging broken builds only)
