Please provide logs from the appliance and the Nodes that you have booted. 
  /var/log/ovirt-server/* on the appliance and /var/log/ovirt.log on the 
Nodes.

I don't know what that command is.  There is qemu-system-x86_64 which is 
used to emulate x86_64 without using hardware virtualization.  But we 
don't support that, since emulation is too slow to be practical.

We require hardware virtualization.  Hardware virtualization support is 
provided by the processor (either Intel VT or AMD-V).  And there are 32 
and 64 bit processors that have this capability.

If your processor is 64-bit and has VT or AMD-V then you can run the 
64-bit version of the oVirt Node or a 64-bit version of a Linux OS (Ubuntu 
or Fedora) on it.  In this case, your host OS can run virtual machines 
that are either 32 or 64 bit with full hardware assist.

If your processor is 32 bit and has VT or AMD-V then you can only run the 
32 bit version of the oVirt Node or host OS.  This means you can only run 
32 bit virtual machines with full hardware assist.  If you try to run a 64 
bit virtual machine it will have to be fully emulated since a 32 bit host 
cannot normally run a 64 bit guest.

If you have a 64 bit processor but you have installed a 32 bit OS or the 
32 bit Node, then you will only be able to run 32 bit guests.  In this 
case, re-install your host with the x86_64 version of the OS or Node.
