Question: I have a Linux server, which runs Ubuntu 12.04.

I installed Xen-server and paravirtualized an Ubuntu 12.10 as guest machine.
Bridged the network, and so far, it worked fine (after much trial-and-error).

The only problem left is, that since the host uses the xen-enabled kernel, it goes to standby after x amount of time.

It didn't do that on the non-Xen kernel.
How can I prevent the Xen-host from switching into standby mode ?

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
