Re: using linux as domU. Error: initializing devices...

Once you install ubuntu-xen-server packages, it also installs vmlinuz-xenU kernels too...

Well forgive me if this is noob question, but how would we expect that dom0 and domU will be from same source if one of them is netbsd-dom0 and vmlinuz-xenU kernels?


Thanks.

Nothing relevant from dmesg or xm dmesg when starting domU?

I used 0x301 instead od hda1 to fix this issue and still same. I also tried mounting volume to /mnt first and then use root="/mnt ro" too. xend.log shows:

This won't work. root="xxxx" is a parameter passed down to the kernel's domU to make it aware of its root partition. It is domU specific.

Well, another Q: Should i install linux under NetBSD? Is this must?

http://www.netbsd.org/ports/xen/howto.html says: "To install the Linux system on the partition to be exported to the guest domain, the following method can be used: install sysutils/e2fsprogs from pkgsrc. Use mke2fs to format the partition that will be the root partition of your Linux domain, and mount it. Then copy the files from a working Linux system, make adjustments in etc (fstab, network config)."

It is a must. I don't know of any linux distributions out there that provide "install from scratch" domU kernels.

Alas, installing a linux domU is not very practical once dom0 and domU do not come from the same distribution.
