Re: using linux as domU. --- almost done

Thanks for your help!

Almost done! Ubuntu booted as domU domain...

No error message, all services initialized. It seems the *only remaining problem* is that, i couldn't specify a console for domU. It boots, and i just do not see "login:".  If i run "xm shutdown linux", it properly shutdowns.

Do you know how to pass console variable to domU kernel?

Cem

Not surprising as /dev is probably a kernfs-like filesystem. What do you
see on console when the linux kernel boots ?
  

I think im just unlucky... I need to play more or maybe better to ask 
someone how he/she installed xen enabled a favorite distribution as 
domU; ie; ubuntu, opensuse, fedora... from their CDs/DVDs.

    

For scientific linux 5 (clone of RHEL5), I boot:
kernel = "/usr/pkg/etc/xen/kernels/vmlinuz-2.6.18-92.el5xen"
ramdisk = "/usr/pkg/etc/xen/kernels/initrd-2.6.18-92.el5xen.img"

both kernel and initrd being provided by the distribution in
scientific/52/{i386,x86_64}/images/xen/
this start the usual SL5 installed in the domU. Once installed, I change the
config to
bootloader = "/usr/pkg/bin/pygrub"
(removing the kernel and ramdisk lines), and the domU loads the SL5
kernel/initrd using pygrub from the domU's root.

Now if I understood you properly you want to boot from an already-installed
linux partition. I've not tried this for a long time, and I don't know
how to build the initial ramdisk (required if your xen kernel has
disk driver build as module).
