This is a clear bug in ovs-dpdk then - it is failing to release memory
when QEMU
After restart ovs-dpdk(which is openvswitch with dpdk lib), memory is
released.
But problem is in product environment, I could not restart ovs-dpdk..
So I think I'd better wait for 10 second to avoid this bug, or use
'-mem-prealloc' to start vm.
The reason I want to remove '-mem-prealloc'

It might be interesting to check the files in:
I don't know if this process is:
1. qemu call kernel API to alloc 40G memory.
2. qemu process is killed by hand.
3. kernel alloc 40G memory, but qemu process is down, then this 40G is left
in kernel.

BTW, I start VM by this command, and then stop it, then memory leak happens.
To compare, I start another VM, and wait for about 10 minutes, and then
kill it as I does above, then no memory leak happens.
So is this a bug of KVM or qemu ?

Or should I use some specific command to stop vm? I want to know if there
someone has the same problem?
The start up command is:
CMD1="$QEMU_CMD
