Usage: multi-qemu [-n] [-c] [-q] -n, --name HOSTNAME_PREFIX specify used hostname_prefix -c, --count count how much VM do you need -q, --queues queues requested queues, use "," to separate more than 2 values -h, --help show this message

example: ./multi-qemu -n vm-2p8g.xsw -c 2 -q vm-2p8g~xsw,vm-2p8g.aarch64
