Re: Paravirtualised drivers for fully virtualised domains

[Himanshu Raj <rhim@cc.gatech.edu>]

Hi Folks,

Could any of you suggest a good recent linux kernel to work with? The latest
2.6.16.13 native version doesn't boot as an hvm guest (No errors, just doesn't
show anything on its boot console, xm list reports it running thought). If you
could hint on this problem, let me know.

Thanks,
Himanshu
