Linux 3.1 with new KVM tool?
Pekka Enberg has announced the release of the second version of the "Native Linux KVM Tool". It offers SMP support, Virtio network communication via TAP-based interfaces and access to the host file system via Virtio-9p. Experimental GUI support using SDL and VNC has also been added.
With these additions the KVM tool has, in a short time, acquired many functions that are needed in typical scenarios and were still missing in the first version. Like Qemu-Kvm, the Native Linux KVM Tool handles the emulation of hardware components such as graphics and network chips, because the KVM hypervisor itself doesn't deal with those tasks.
Enberg is "officially aiming" to merge it into the tools directory of Linux kernel version 3.1, which is due for release next autumn. Over the past few months, the kernel developers have added more and more userland programs that closely cooperate with the kernel, for example the Perf performance monitoring tool and a range of diagnostic and test tools. The KVM tool is also likely to appear in various distributions via this channel, although it is in many areas still far from offering Qemu-Kvm's range of features. However, the Native Linux KVM Tool has reportedly already achieved better results in some I/O benchmarks.
