Fixes the longstanding RHEL 5 i386 smp boot problem as well as the
recent Intel Core regression. Large page support improves performance
for dedicated virtualization hosts, while vmware vga and more std-vga
resolutions should improve the home user experience.
Changes from kvm-61:
- fix oops running external module on 2.6.25 due to mmdrop (Andrea
Arcangeli)
- backward compatibility for 2.6.25 desc_struct changes
- fix memory alias mixup (Uri Lublin)
- add file:// migration protocol (Uri Lublin)
- fix reading from character devices with flow control (Jan Kiszka)
- large host page support (Marcelo Tosatti)
- fix screen corruption with high resolutions (Andreas Winkelbauer)
- implement vmware vga for kvm (Soren Hansen, Anthony Liguori)
- even more resolutions for -std-vga (Andreas Winkelbauer)
- code cleanups (Carlo Marcelo Arenas Belon, Harvey Harrison)
- allow up to 16 vcpus (Anthony Liguori, me)
- allow up to 16 memory slots
- improve vcpu_run error reporting
- fix host crash on hosts without EFER (Intel Core not 2s)
- drop kvm private segment descriptor in favor of Linux' desc_struct
- stat counter for hypercalls (Amit Shah)
- fake values for MSR_PERF_STATUS (Alexander Graf)
- needed for Darwin/OS X
- better root pagetable unpinning (Marcelo Tosatti)
- paravirt clock fixes (Glauber Costa, Marcelo Tosatti)
- avoid host hang when guest sets APIC timer to zero
- also fixes live migration of Windows 2000 guests
- fix RHEL 5 i386 smp boot due to timer interrupts being routed to all vcpus
Notes:
If you use the modules bundled with kvm-62, you can use any version
of Linux from 2.6.17 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.
