Ubuntu server on VB 3.2.* - dev disk does not exist

Hello
I'm trying to install ubuntu-10.04-server-i386 in Virtualbox on Windows XP Home (for use as a Drupal development server) using the instructions here
https://help.ubuntu.com/community/VirtualBox
and here
https://help.ubuntu.com/community/Ubuntu_as_Guest_OS

However, the Ubuntu server will not start properly. Instead it goes to an initramfs prompt as follows

Code: Select all

Gave up waiting for root device. Common problems:
— Boot args (cat /proc/cmdline)
— Check rootdelay= (did the system wait long enough?)
— Check root= (did the system wait for the right device?)
— Missing modules (cat /proc/modules: ls /dev)
ALERT! /dev/disk/by—uuid/7fe12763—234b—4a75—910b—3fb00Bebb2f1 does not exist. Dropping to a shell!
BusyBox v1.13.3 (Ubuntu 1:1.13.3—1ubuntu11) built—in shell (ash)
Enter 'help' for a list of built—in commands.
(initramfs) _
Another thread suggested typing 'exit' after a while but it just repeats the same output.

It seems the root disk doesn't exist. I allowed the installer to set up partitions to its own recommendation (Guided) so there are two partitions.

The host disk is SATA. The CPU is a dualcore but I've only enabled one CPU on the guest within Virtualbox. Also, I had to enable PAE mode as without it Virtualbox crashed every time I started the guest with the message "Virtualbox GUI has encountered a problem and needs to close". PAE wasn't mentioned in the instructions mentioned above.

I've tried changing the various other disk parameters in Virtualbox (without fully understanding them) but no luck.
I had this problem on VB 3.2.0 and 3.2.2.

I've posted this at the Ubuntu forum too where someone has the exact same problem on a Solaris host.

Any help would be appreciated.
Thanks

I've gone to Ubuntu server 9.10 which works.
It still crashes VB if PAE isn't checked. Not a problem but I thought it might exit more gracefully.

Still open to ideas about v10.4 if anyone has them.

I'd like to install Ubuntu 10.4 server on Virtualbox too.

Ubuntu server requires that you have PAE enabled. Other then that it works great.
I have been using the Ububtu server since 8.04 and have every release since then and in every release of VBox that has been released with no problems.
I don't use the OSE version though so I can't tell you about that. The PUEL version works flawlessly with Ubuntu.

You use VB 3.2.x, what if you install Ubuntu Server when you set the HDD to IDE controller instead of the default SATA?

Easy fix. Go into settings and remove your virtual hard drive file from the SATA controller. Add a new SCSI controller and reattach the virtual hard drive file. DONE :D

DONE!Worked for me in guest Ubuntu Server 10.10 Maverick with linux-virtual + linux-headers-virtual installed.

TNX!
