[Bug 946022] Re: KVM Guest Hangs at Booting from hard disk

[Konstantin L. Metlov]

I have a similar problem trying to launch any Ubuntu 12.04 Precise guest
(built with VMBuilder, downloaded from cloud-images.ubuntu.com or even
the installation ISO images of different flavors) on 10.04 Lucid host.
This is unaffected by different kernel options (lapic, acpi_pm etc) and,
it seems, happens before the kernel starts. I have tried enabling debug
in grub and the last lines I see about loading initrd, malloc and
several reallocator.c traces, then hang.

When hanged, the kvm uses very little memory (about 30 mb) and spins,
consuming 100% CPU.

What is strange that, at the same time, the host perfectly runs about 10
Lucid guests.
