Still, two issues with that Kubuntu instance: - grub segfaulted, failing to install the boot loader on the hard disk image (I ended up using lilo instead); this also happened previously when trying to install debian testing amd64 *without using kqemu* (maybe some grub bug?); - without or without the kernel option clock=pit I got, already at boot time: Losing some ticks... checking if CPU frequency changed [...] warning: many lost ticks Your time source seems to be instable or some driver is hogging interupts and now, about 1.5 hour after booting, the guest clock is about 1.5 hour ahead of the host clock (maybe because the host has been idle and working at about 1/2 the full clock speed?) This clock shifting did not occur with a Windows XP Pro guest, which usually remained late by less than 1 minute.

Sounds like a kqemu bug. 0x0d == 14 == page fault. The only person who
can help you here is Fabrice...

(apparently immediately after (very briefly) showing a progress bar with

following:

The above crash does not happen when qemu-system-x86_64 is invoked with
the additional option -no-kqemu.
In case this issue is already known: is there any way to avoid this crash

disabling kqemu?

Meanwhile I got some hope for a temporary trick when I tried the option -smp 2 and this error did not show up... but then I noticed that, with the -smp 2 option, kqemu is disabled...
