KVM: the Latest from the Development Team
Chris Wright, Red Hat
- kvm has replaced xen as the VM integrated directly with the
kernel.
- qemu emulator is heavily reliant on the kvm device driver.
- Machine-to-machine paradigm for servers rather
than user-target in embedded.
- Support for direct control and communication with host's
peripherals, esp. PCI, is being added.
- Guests can run at 80% native speed although implementation remains buggy!
- Challenges include guest-host coordination of memory (via Nested
Page Tables) and scheduling.
