Hi list
We're using LXC with libvirt_lxc to run MySQL, we have thousands
instances.
In recently one years, we met problems frequently. The most serious
problem is the process libvirt_lxc can't be accessed, can't ping, there are no
any response. the process status of it is Rs, and all of the sub processes of
it are in the same status , that's Rs. The most sad thing is we
can't kill these processes even with: kill -9 $PID ; or kill -15 $PID.
Can't login with : virsh console $name
Our host environment: OS kernel: 2.6.32-431 , CentOS release 6.3
(Final)
Anybody ever met the same problem with us? How do you solve these
problem?
Any suggestions are welcome!
BR
Thanks a lot.
