Re: heterogeneous instance types


That is a good idea if the networking service supports it.  One of the things we've been thinking about is how to best to make the virt subsystem more modular.  It really needs a better driver-style interface with plugins for non-libvirt virts, I think.  

Mikyung actually had to build a bare metal TFTP-boot image management system for the Tilera system because it doesn't currently support KVM or Xen.  I could see some HPC folks interested in managing bare-metal XCAT or Perceus machines.
