Linux kernel 2.6.21

Kernel 2.6.21 was released yesterday, a few of the more interesting highlights:
- VMI now in default kernel (this is VMware’s layer on top of paravirt_ops), theoretically a fully paravirtualized Linux kernel on top of VMware might be do-able now
- updated KVM code which includes some paravirt_ops support and live migration
- clockevents and dynticks
The dynamic clock tick stuff is best covered over at LWN (see Clockevents and dyntick). This could have positive impact on power consumption and performance (particularly in virtualized environments). It will be interesting to see if certain virtual environments can now keep accurate time with a kernel such as this.
