hi, thanks for your time. I ported the pvonhvm with this method: Ubuntu 10.10 was comply to the pvops, so it has it's own blkfront, so I just add platform-pci to ubuntu 10.10 source, and then compile, that's ok, the platform-pci was based on the source linux 2.6.32, which come from debian 6.0, the debian 6.0 support pvonhvm.
