Re: [Xen-users] What packages ubuntu-xen-server & ubuntu-xen-desktop are up to on intrepid

[Paul Schulze <avlex@xxxxxxx>]

Hi Boris,

I am currently thinking of upgrading to Ubuntu Intrepid myself, or  
backporting xen-3.3 until an official backport is made (which seems  
to be in progress, from what I read). However, the biggest problem at  
the moment seems (as you already mentioned) to be the kernel. Even  
though all other packages that were part of Ubuntu in the past are  
included in the new version as well, the changelog of the xen-3.3  
source package states, that users are on their own to find a suitable  
kernel. Do you (or anyone else) know, if the Ubuntu Hardy Dom0 kernel  
works with Xen and if so, does it support use of the new features  
(f.e. like PvSCSI, amongst others), or are there problems to be  
expected?
Thanks,


Paul.
