You could certainly build the kernel within DomU, but you''d have to
copy
it out of DomU into Dom0, since Dom0 has to load the kernel for you
[unless you run fully virtualized kernel, in which case you''d just
build
the kernel as per a standalone system...]. You could use something like
"ssh .../vmlinuz dom0name:<wherver>" to copy the kernel,
assuming you
haven''t prevented ssh from getting from DomU to Dom0 with your firewall
settings in Dom0 (or DomU firewall settings, if you have any of those).
