I am currently trying to install Ubuntu 9.04 server as DomU using hardware virtualization. Whenever I boot up the domain, the splash screen works well, but as soon as I select "Install Ubuntu server", the domain keeps hanging with 100% CPU utilization indefinitly.
About 50% of the time, the following message is shown, the other 50% of the time, no message is shown at all:
ACPI: DMI BIOS year==0, assuming ACPI-capable machine
I tried various settings of acpi=0, acpi=1 in the domain's config file, I tried specifying acpi=off as kernel argument, I also tried acpi=force.
I am now run out of ideas, why the kernel won't boot. Neither "Install Ubuntu server" nor "Check disk for errors" will work, but Memtest86 works fine from the ISO.
Anybody got a hint how to proceed. I have to confess that I am quite new to Xen.
Edit: added, that it is for the server version.
I tried upgrading from previous installs as well. I could install 8.04 LTS and upgrade to 8.10, but after an upgrade to 9.04 the kernel hangs again. I suppose it "simply" is a kernel issue of 9.04.
Have you tried using the alternate install CD/DVD? Sometimes there are problems with ACPI and the GUI install. It happens on the desktop version a lot as well. Most times the problem is resolved with the alternate install CD/DVD
