Hello,

* COLO is a VM fault tolerance solution. Currently Remus provides this
function, but it buffers all output packets, the latency is unacceptable.
COLO addresses the problem, it can greatly improve the VM availability.
Add cmdline switches to 'xl migrate-receive' command to specify
a domain-specific hotplug script to setup COLO proxy.
Add a new config var 'colo.default.agentscript' to xl.conf, that
allows the user to override the default global script used to
setup COLO proxy.

read_record() could be used by primary to read dirty bitmap
record sent by secondary under COLO.

it.

Currently, libxl__domain_unpause() only supports
qemu-xen-traditional. Update it to support qemu-xen.
We use libxl__domain_resume_device_model to unpause guest dm.
