XAPI plugin for host updates
-
We started to work on a XAPI plugin that will help to:
- check for updates on a host
- update a host
Obviously, this is only a part of the whole logic to manage updates easily. The rest will be included into XO!
-
I tryed it and it worked. but my xo says " XS74E001 Public Availability: Security fixes to Xen May 8, 2018, 1:00 AM (19 days ago) restartHost". Do i have to install it on XCP-ng
? -
What did you try exactly?
edit: because today, if you see updates in XO for XCP-ng, it's because it's still using the old (XenServer) way to update and it doesn't work correctly (or doesn't mean to work) with XCP-ng.
-
i tryed https://github.com/xcp-ng/xcp-ng-updater/tree/master/SOURCES/etc/xapi.d/plugins. Servers are in XCP-NG Free/Libre Edition and, In XEN ORKESTRA I saw this patch for all hosts so i upgraded them succesfully and then left them to continue working.
-
Can you describe each steps you have done?
-
Copy updater.py in /etc/xapi.d/plugins/, Check and run script. Simply.

I mean I know that, we did the script, but could you waited a bit
(it's not finished yet ). Plus we are packaging in into RPM, then we'll create the UI in XO to use it. If you have access on the host, it would be faster to just yum check-updatesand/oryum updatedirectly
The concept is to expose it in XAPI for external tools (like XO) to update a whole pool at once
Anyway, glad to know we have some ultra early alpha testers
-
If our host is up to date, should we run the update script for XOCE and from SSH on the host?
I should mention that I have updated XOCE about a week ago and I notice that there is a Backup NG as a choice in the menu. -
I don't see the connection between updating Xen Orchestra from the source and XCP-ng.

@olivierlambert said in [Work in progress…] XAPI plugin for host updates:

Sorry. I should have read the entire thread. My mistake

Screenshot of a working piece of code:

Here it is: https://xen-orchestra.com/blog/xcp-ng-updates-from-xen-orchestra/
Available in XO for 5.20 release!

Nice feature, good job team
-
Will this feature come to debian?
-
I'm not sure to understand your question. What do you mean?
