Starting with a pre-historic kernel for a new project is hardly ever a good choice. > d. No VGA adapter > e. Serial console > f.

Is KVM code in Linux kernel 2.6.26 reliable? That kernel is 2 years old, last version is 1.5 years old, and kvm was still quite young into mainline at that time. There is a good chance you may hit some bug that was fixed since then. > b. Will latest KVM code from linux-kvm.org run on Linux kernel 2.6.26? kvm-kmod builds down to 2.6.24, but it is likely only tested down to 2.6.27. And you will miss quite a few relevant performance optimization due to limitations of 2.6.26. Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
