Xen is a para-virtualisation system for x86. It provides a secure way to run a
lot of copies of Linux at once on a single PC. To get the speed it doesn't
emulate a PC exactly (as vmware tries to) but requires the kernels are
"Xen friendly".
The Xen guest0 kernel is the kernel that runs all the real devices and supports
the actual hardware. The unpriviledged guests then talk to guest0 via
virtual hardware interfaces.
Ok - I'm a bit confused.
Does this mean 'guest0' is equivalent to vmware-host-os (i.e I boot
off this kernel on the real hardware), and 'guestU' (unpreviledged) is
the kernel installed inside the 'vm'? (aka vmware-guest-os)
or is it something else?
