hi, This patch makes ssl relocation server listen on 8003 if enabled. Whether to start ssl relocation server now controlled by xend-relocation-ssl-server. So ssl and non-ssl relocation server can run simultaneously. You can also only start ssl server or only start non-ssl relocation server. When mix deploy xen 3.2 server (has no ssl support) and 3.3 servers, start ssl and non-ssl relocation server simultaneously can keep backward compatibility. It's also more reasonable to have separate ports for ssl and non-ssl. In this patch, also renames xend-relocation-tls to xend-relocation-ssl. Signed-off-by: Zhigang Wang <zhigang.x.wang@xxxxxxxxxx> thanks, zhigang Make ssl relocation server listen on different port
This patch makes ssl relocation server listen on 8003 if enabled.
Whether to start ssl relocation server now controlled by
xend-relocation-ssl-server. So ssl and non-ssl relocation server can run
simultaneously. You can also only start ssl server or only start non-ssl
relocation server.
When mix deploy xen 3.2 server (has no ssl support) and 3.3 servers, start
ssl and non-ssl relocation server simultaneously can keep backward
compatibility.
It's also more reasonable to have separate ports for ssl and non-ssl.
In this patch, also renames xend-relocation-tls to xend-relocation-ssl.
