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.

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

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

We're testing both 32 and 64 bit builds on a mixture of Xeon and
Opteron. Many of my colleagues use Opteron machines as their personal
test boxes as well. I've just fired off a test run explicitly on an
Opteron-based Sun V20z to make sure all is well: it it has booted and
started a guest just fine.

Regards,
James
