Subject: [PATCH RFC 0/6] COLO-Proxy: Make Xen COLO use userspace colo-proxy
Date: Thu, 26 Jan 2017 14:36:03 +0800 [thread overview]
Message-ID: <1485412569-7431-1-git-send-email-zhangchen.fnst@cn.fujitsu.com> (raw)
Hi~ All~ Happy Chinese New Year~~
Because of some reason, We no longer support COLO kernel proxy.
So we send this patch set to make Xen use userspace colo-proxy in qemu.
Below is a COLO userspace proxy ascii figure:
