Re: [Xen-users] para- and full-virtualization on same system?

Yikes! Do the fully-virtualized OSs need to be "well tested" - I thought
the idea was that the OS would just work...or do you mean that the OS
may not recognize some of the devices being provided by the virtual machine?
Just 64-on-64 for now - for paravirt domains, the guest interface must
match
the hypervisor. A compatability layer *may* appear at some point, but
it's
not there yet.
I know that there are many optimizations yet to be made, but given
current implementations, is there any performance comparisons between
running a 32-bit xen-aware OS para-virtualized versus full-virtualized?
For instance, its been said that a para-virtualized guest OS may be 3%
slower than normal - how much slower would the same guest be if running
fully-virtualized?
Thanks!
