[Xen-users] Need help in compiling and installing Xen-3.4.1 on Lucid

[Daniel Mathew <danieljmathew@xxxxxxxxx>]

Hi,

I am a Xen newbie and have been trying to get Xen-3.4.1 working on my Ubuntu Lucid (kernel version 2.6.32-21) system, using kernel 2.6.18.8 as dom0. In attempting this, I ran into the following issue. On booting into Xen, I get these errors:

Mounting none on /dev failed. No such device.
...
Gave up waiting for root device. 
...
Alert! Could not mount /dev/sda1 as root device. Dropping to a shell.

After this I get a (initramfs) shell. I figured out that this is due to the fact that a 2.6.18 kernel doesn't support devtmpfs, which is the /dev filesystem Lucid uses. Now I would like to compile a newer kernel and use it as dom0. However, I could not find Xen-patched kernels that might have devtmpfs support (version >= 2.6.32). What are the steps I should take to get, patch and install such a kernel as dom0 (rather than falling back to the default kernel that Xen make scripts download from Mercurial repos)?

[Please point me to any documentation that I might have missed regarding this.]

Regards,
D.
