[Xen-users] "Cannot find root device" while initializing dom0

[Paolo Victor <paolovictor@xxxxxxxxx>]

Hello,

I've been trying to install Xen 3.3, but when it tries to boot Dom0 it displays the message:

"Gave up waiting for root device. ALERT! /dev/by-uuid/xxxx does not exist"

And boots the recovery shell. I've tried both compiling Xen and Dom0 from source (Xen 3.3.1, kernel 2.16.18.8-xen) and using Ubuntu's packages (Xen 3.3, kernel 2.6.24-32-xen), with no luck. Native Ubuntu 8.10 boots normally, though, and the menu.lst's device UUIDs are correct.

The system I'm trying to install Xen has a x86_64 processor and 4 SATAII hard drives. I've read somewhere (sorry, I couldn't find it again) that Xen could have issues on waiting the hard drives to "spin up", so I tried setting the kernel's rootdelay option up to 480, but it didn't work either. I also tried disabling the other 3 hds that didn't contain the root partition.

At the recovery shell, I can see that none of the /dev/sd* devices aren't listed, as expected, but the some drivers were loaded, according to the /proc/modules file:

-libata
-pata_api
-pata_it8213

-ata_generic

What do you think about this? Have any of you ever come across such problem? I'm thinking about trying a clean install on an IDE drive, but that would really be the last resort.

Thanks in advance for your attention,

Paolo Victor
