Everything I tested still works, but undoubtedly a few rough edges remain. The merge brings too many goodies to list; have fun exploring. I've also thrown in a network latency improvement when using the tap device (bridged networking); on may machine this reduces guest->host ping round trip latency from 940 microseconds to 78 microseconds. Less visible but also noteworthy is the removal of page->private use for guest pages, an important step towards swapping guest pages. As usual, if you have an issue please try with -no-kvm-irqchip and report. Changes from kvm-44: - don't use page->private for guest pages (Izik Eidus) - x86 emulator cleanups, simplifications, and fixes (Laurent Vivier, Qing He) - apic round robin delivery mode cleanup (Qing He) - merge qemu-cvs - fix compilation on older kernels (Rusty Russell, me) - reduce tap networking latency - fix FC6 x86_64 booting with -no-kvm - fix code dump on exception Notes: If you use the modules bundled with kvm-45, you can use any version of Linux from 2.6.9 upwards. If you use the modules bundled with Linux 2.6.20, you need to use kvm-12. If you use the modules bundled with Linux 2.6.21, you need to use kvm-17. Modules from Linux 2.6.22 and up will work with any kvm version from kvm-22. Some features may only be available in newer releases. For best performance, use Linux 2.6.23-rc2 or later as the host. http://kvm.qumranet.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
