Hi~~~ All~

No news for a long time, anyone can give me some comments?


A question is why use two kinds of colo-frames? This seems not good as lots of the code were duplicated.

Because Xen colo-frame based on Xen Remus.
Remus do some job like the migration job in qemu/kvm, and in Xen HVM we can not do migration in qemu,
So colo-frame code must running in Xen side.
In addition, Xen HVM use qemu to simulation device that Colo-proxy and Replication can use same one codes in qemu.

This series focus on COLO Xen support.
We add a new chardev socket in colo-compare as the way
of communicate with Xen COLO-frame.
Xen part:

This series is a frame, have some TODO job depend on this patch:

Zhang Chen (3):
   COLO-compare: Add new parameter for communicate with Xen colo-frame
   COLO-compare: Add Xen notify chardev socket handler frame
   COLO-compare: Add colo-compare Xen notify
