[libvirt] can't remove cgroup files of the domain, thanks!



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 :

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

 

 

 

 

 

^C

root vmc-22:~#

 

 

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

 

Thank you very much!
