Xen users - Feb 2006 - domU boot from cdrom..?

How can I have one of my guest systems boot directly from a cdrom? I see that it
is possible on the vmx machines using vmxloader as the kernel but what about non
vmx guests?

is this possible, if so how? i have not been able to find any place that
specifies it... all install have been with a copy of an existing OS.

thanks

Miguel,

you could make an ISO image from the CD-ROM and use that for booting.

This is an entry I use for starting off a NetBSD-ISO:
> disk = [ ''file:/var/xentemp/i386cd-3.0.iso,cd0a,r'', 
> ''phy:/dev/LVMvg01/razalde,0x301,w'' ]
You simply have to adjust pathes and mountpoints to your needs. It works 
in Xen 2.0.7, I did not try that in 3.0.x.

We can do it in Source Mage :)
One of our developers is putting this together:
http://wiki.sourcemage.org/Install_under_Xen

I''ve installed off our install cd and such, however it''s
because our
installer doesn''t rely on anything fancy to make it work.
it''ll function
without any modules loading or any fancy kernel patches. Your mileage
may vary with other installers. Of course you could give Source Mage a
shot too, you might like it ;)
