Illumos boot

[Peter Grehan]

Hi Matt,

>> -s 0,hostbridge

  Things should work if you leave out the hostbridge. The PCIe 
capability that is tacked on to this will make Illumos use MSI/MSIx for 
the virtio adapter which apparently hits a bug in the driver. Without 
it, the virtio driver will fall back to legacy interrupts. This also 
means that the virtio adapter will be confined to slots 3/4/5/6.

  (I believe Andriy Gapon (cc'd) has a fix for this in Illumos)

later,

Peter.
