Subject: [PATCH V3 0/7] COLO-Proxy: Make Xen COLO use userspace colo-proxy
Date: Fri, 17 Feb 2017 10:18:22 +0800 [thread overview]
Message-ID: <1487297909-1885-1-git-send-email-zhangchen.fnst@cn.fujitsu.com> (raw)
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:
