HI all:

I am now working with libvirt 1.0.0 and come up a problem when I try to destroy a domain, The libvirtd just waiting rmdir command to return for hours, but it seem to never to return ..

The stack is :

0x00007fa752261287 in rmdir () from /lib/x86_64-linux-gnu/libc.so.6

root@vmc-22:~#

when I use command “service libvirt-bin stop”, I can stop libvirtd;

but rmdir command still never return:

root@vmc-22:~# rmdir /sys/fs/cgroup/libvirt/qemu/win7_gl//emulator

root@vmc-22:~#

Is someone know this problem? How can I solve this problem?

Thank you very much!
