[Qemu-devel] [PATCH 18/18] Introduce "kemari:" to enable FT migration mode (Kemari). |
Date: |
Wed, 23 Mar 2011 13:10:26 +0900 |
When "kemari:" is set in front of URI of migrate command, it will turn
on ft_mode to start FT migration mode (Kemari). On the receiver side,
the option looks like, -incoming kemari:<protocol>:<address>:<port>
