Fedora xen - Jun 2006 - RE: FW: [IA64]We have successfully booteddom0/domU/domVTI (xen/ia64) on FC5

    Currently the ext3 is compiled as module, however initrd doesn''t

ext3 to be kernel built-in, and then domU can boot up immediately.
Thanks

Could you provide more details how you''re configuring it to use the
initrd?

Right -- my question was why don''t initrds work.  This is really a
requirement given how some of the early boot process works.  There are
ways you can hack around it, but they''ll always be just that, a hack.

Hi, Jeremy

I made a patch to support initrd of domU.
I think it work good in the case of using xen-ia64-usntable.

I''m checking fedora-xen-ia64 now, please wait.
If necessary, I''ll make a patch. :-)

Best Regards,
