Hello,
We are running a couple of VMs using the qemu command on ubuntu 14.04. It seems
like there is a corruption on the socket. It crashes on its on after a day or
so of light activity.
Is this a known issue?
Please let me know if this is the right place to post this or if you can help.
thanks
pawan
