Following document 'COLO-FT.txt',
I test colo feature on my hosts
I run this command
Primary:
sudo /usr/local/bin/qemu-system-x86_64 -enable-kvm -m 2048 -smp 2 -qmp stdio -name primary \
-device piix3-usb-uhci \

children.0.file.filename=/var/lib/libvirt/images/1.raw,\
children.0.driver=raw -S
Secondary:
sudo /usr/local/bin/qemu-system-x86_64 -enable-kvm -m 2048 -smp 2 -qmp stdio -name secondary \

file.backing.driver=qcow2,\
file.backing.file.filename=/mnt/ramfs/hidden_disk.img,\
file.backing.backing=secondary-disk0 \
-incoming tcp:0:8888
Secondary:

}

Primary:
{'execute':'qmp_capabilities'}
