lenny amd64 and xen.
I''ve installed debian lenny amd64, it is frozen now. I''ve install kernel for xen support but it doesn''t start. It says "you need to load kernel first" but I''ve installed all the packages concerning xen, also packages related to the kernel. Perhaps lenny doesn''t support xen anymore? Any solution?

snapshots on xen
Hi all. I''m using sles11 for my xen servers. I would really like to be able to do hot snapshots of disk AND memory, and then have these snapshots backed up to tape or off site for disaster recovery. I''m thinking this would be done weekly or monthly, not nightly. Two questions: 1) Is this even possible? 2) I could probably have the systems shutdown to make a clean backups, but

Xen virtual interface settings
I''ve been mucking with xen for quite a while but recently started focusing on custom network setups. I''d like to be able to create VMs on the fly from a base image and set network settings in each without booting the image up. This strange setup is for a classroom environment. At the beginning of the quarter the instructor would run a script that creates all the
