Xen devel - Dec 2005 - RE: Resolved - domU won''t recognise my block devices

I recompiled without devfs and now a guest works fine.

Can someone please confirm that we should be building the -xen (not xen0
+ xenU) kernels and using those? If that''s the case, then the default
config is broken for me as devfs just doesn''t work.

Of course, the initrd tools under debian want devfs, so to have a
devfs-less kernel I had to move over to initramfs-tools... but my
network booting off AoE is working nicely under that now after some
tweaking...

Thanks

James

Arg, that''s a bit broken... things shouldn''t really be quite
like that.

DevFS works fine in dom0 but breaks things within domUs... I don''t know
quite if it b0rks on the new xvd* devices, but certainly for hd* and sd* it 
will not work. Hmmm.

Given DevFS is deprecated, do we really need it in the default config?

Cheers,
Mark
