Hi,

During the boot process of the livecd (latest x86_64 ISO from
26-April-2010) on KVM, I get the following:

I just saw someone else with a KVM crash and DragonFly:

Hi Justin,

I don't know how this guy is trying to run our i386, but it is
certainly working for i386. island.quantumachine.net is a VM on KVM
and Jan has done some test on DFBSD/i386 over KVM also. He shouldn't
be pressing a lot of keys in the loader prompt and also in that prompt
it is asking for the loader, not the kernel.

It is on x64 where I encounter this issue, right the same as he does
in that screenshot.

Nevertheless, thanks for the link :-)

Cheers,

Just FYI, he isn't running x86, he's running x86_64. See that %rbx?

Alex,

Yeah, indeed, I got confused by the PCBSD screenshots.

Hi Dillon,

After adding the nop as you told me and building an ISO with it, here's the new
panic:

Hi,

I've tried several FBSD flavours with different issues.
FBSD 6.4 and above doesn't seem to have any issue, and 6.3 and below just fail
randomly, so I haven't been able to establish any relationship.

I keep searching ...

This could be related to the use of superpages to map portions of the
kernel on x86_64. Hardware KVM support has serious issues with
FreeBSD's dynamic superpage support and they have to turn it off to
run reliably, I wonder if the static superpages have the same problem.

Hi Matt,

So I guess if we could disable static superpages, we could make sure that's the
issue. But something tells me that it can't be done, at least in an easy way.

Thanks,
