[linux] xenserver renew license xe command line

在 license 過其實使用 xe command line 會出現

Your license has expired. Please contact your support representative.

因為手邊沒有windows 的機器不能開xencenter去 renew license ，
先找到了

How to fix the XCP expired license issue
http://xenapiadmin.com/tutorials/21-how-to-fix-the-xcp-expired-license-issue

去更改 expiry 時間但是不work


Renew free license using CLI only - Server Installation - Discussions
http://discussions.citrix.com/topic/269333-renew-free-license-using-cli-only/
後來看到這邊文章，給出了renew的url

Citrix Systems, Inc.
http://deliver.citrix.com/go/citrix/xenserver_activation


填完以後等收email拿license file
然後使用

xe host-license-add license-file=filepath

就成功了

ex:

[root@xenserver-hy03 ~]# xe host-license-add license-file=l.txt
License applied.
[root@xenserver-hy03 ~]# xe vm-start uuid=e12978e9-1f71-da3b-d082-e81d6cc7918d
