I get the following, but Googling this I see you consider these harmless: Failed to read /local/domain/0/device-model/1/script (No such file or directory) Failed to read /local/domain/0/backend/console/1/0/script (No such file or directory) I am just writing the error messages down at the moment because I don't have a shared writable partition. Another error I get is this, which perhaps isn't so harmless: Attach vnd0d vnd1 dos partition I/O error Does this mean anything to you? > Also set ddb.onpanic=1 in /etc/sysctl.conf to get more infos in case > of panic.

Do you mind if I clarify the following? Is it enough to extract the kernel and ramdisk from the DVD ISO and put them in NetBSD / or do I need to download a separate Xen kernel and ramdisk from the SL/Debian website? Will the same kernel work for domU installation and daily use? I have even tried compiling a vanilla kernel and ramdisk, which works for my Slackware domU but not for these other distros. -- Gerard Lally
