Qemu-cvs as of yesterday has been merged into kvm. 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.
