Hello all,

I have recently compiled kvm-36 in my Ubuntu Desktop 7.04 64 bits 
running 2.6.22. I can load the AMD module without problems. The 
issue started when I tried to install OpenBSD 4.1 on a Virtual 
Machine and It could not manage to write the MBR on disk. That 
should not happen. I also tried to install an Ubuntu desktop and 
server machines 32 bits and both of them got stuck on installation 
when configuring fdutils, I have no idea why this happens.

Eventually I get to install a Debian netinstall with the most basic 
configuration and it worked. These are the tests I have made. By the 
way I checked that the Ubuntu machines did write in my 4G feisty.img 
file.

Is anyone having problems with AMD64 and 2.6.22 kernels? Has anyone 
a hint about what could I do to get these machines running?

  
        

What was the last kvm version where this worked correctly?

      

I'm using two machines for testing KVM. In machine "A" KVM worked 
good. This is a Feisty 7.04 32 bits with 2.6.20-16 Ubuntu standard 
kernel  with kvm installed apt way.
    

Is this an Intel or an AMD machine?
  

The machine "B" is the one I have mentioned before and It's using a 
2.6.22 manually compiled kernel. It has been able to install only 
Debian netinstall. I would like to know if there is some kind of issue 
with kvm and this kernel or with AMD64.

    

It doesn't seem to be related to the machine being AMD.  If you can 
provide an example where just one thing being different causes something 
to stop working, that would help us isolate the problem.  Examples can 
be the host kernel, host cpu type, or kvm version.
