Whats QEMU?
QEMU is a set of dynamic code generation tools that can take binaries for
one CPU architecture and run them on a different CPU architecture with some
additional processing to map system calls and some other incidental stuff.
It works for SPARC, POWER, and Alpha at the moment, with work being done for
IA32 and x86_64 architectures. It takes the original opcodes and dynamically
builds native instruction streams for the host architecture, which makes it
significantly faster than the pure emulation approach used by Bochs.
It's never going to be native performance, but if you're replacing older
hardware, it may be good enough to do what you need it to do.
At present, one can use it on intellish hardware with LVM modules to run
fully virtualised guests.
From my POV it has a great advantage over xen in its being a standard
part of the Linux kernel.
Presumably it will appear in l390 at some point.
