Install multiple xenserver patches at once

Leave a comment

I came across a need to install multiple patches manually (via SSH) on one of my xenservers. It’s quite tedious to do this manually so I found a way to here.)

Download all the patch .zip files to a directory your xenserver can access. Then, extract them all with this command:

find *.zip -exec unzip {} \;

Next, upload all the .xsupdates:

find *.xsupdate -exec xe patch-upload file-name={} \;

This spits out a bunch of UUIDs. Make note of these. You will also need to get your host-uuid by using the

xe host-list

command.

Lastly, a quick for loop applies the patches we want (replace the UUIDs with those of the patches uploaded earlier and the host-uuid with yours)

for file in c3520494-be00-4133-afb3-adf8ab5edb11 7fea2d85-7ce1-428c-a92f-57e37551d6f1 d9862b7f-9be6-4672-b9a8-4f52f776fd03 a424dfe5-8be8-4bd6-a49e-62620e369a43 e28bb0ae-e43f-46d9-9147-c7dc712508eb; do xe patch-apply uuid=$file host-uuid=46f8ef28-8ee1-44b5-967c-b8e48585094b; done

That did the trick for me. After applying the patches I came across this post which appears to have a much better script. Whatever works.

Manually apply patches to Citrix Xenserver

Leave a comment

Citrix Xenserver has many features, all of which are now free as of Xenserver 6.2. XenCenter, however, still expects a support license to use some of its features. One of those features is applying patches. Fortunately it’s easily done via the command line. Their site has documentation on how to do this. Below are my “cliff notes”

  1. xe patch-upload file-name=<filename>
    Note: .xsupdate is the extension of xenserver updates
  2. Wait a moment, then copy the UUID that it outputs
  3. xe host-list
  4. xe patch-apply uuid=<UUID copied from patch-upload>  host-uuid=<host UUID as out put from xe host-list>

If you’re in a pool, instead of xe patch-apply, you can do xe patch-pool-apply <UUID> to apply the patch to all pool members.
