If the code comes in to support it, and if it doesn't hurt full hardware virtualization, kvm can be extended to support it. I have no plans to work on it myself but will review and accept patches. It's also something for the Linux community in general to decide: if we want separate interfaces for paravirtualization and full virtualization (lhype and kvm) or a merged interface. I can see arguments in favor of both positions. > As a follow-up question, would it be possible then to run a 32-bit > guest on a 64-bit host? That is possible now, and hopefully will continue to be possible. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- Take Surveys.
