Thats a great question.
I provide my own repos which sync to Centos/Plus/RPMForge/Gitco upon my choosing, normally once a month.
I then test any new updates before going live with a foreach loop, yumming hosts in my list.
I did the same is an MS$ env and am unsure of a better way. ÂBut I've never managed more then 1,000 nodes.
Any one care to share there methodology?

How do you facilitate providing updates to the domU's, for example, when
package upgrades need to take place?

I think what he's probably asking more than anything is since you have multiple OSs running off a single LV who gets the job of updating?
I would assume that you have to shutdown the other domains (maybe pause?), remount /usr as read/write, do the updates using one DomU and the unpause the others. I think this would be problemic though because you just updated one portion of the OS and didn't touch anything else (configs etc..).
This whole method makes me a bit nervous. Either that or you just never update!
Could you give us more detail on your update procedure please.
