We're still recovering from the lapic merge; in addition many patches that were held up waiting for lapic have been merged.

Changes since kvm-37:
- fix fpu indication for Solaris (Amit Shah)
- Avoid GFP_NOWAIT allocation in mmu
- Fix runtime smp_processor_id() warning in lapic
- Move vcpu loop into subarch independent loop
- Rename kvm_arch_ops to kvm_x86_ops (Christian Ehrhardt)
- Fix missing "genapic" on i386 (Eddie Dong)
- Fix lapic hrtimer migration (Qing He)
- Fix lapic 64-bit division on i386 (Jindrich Makovicka)
- Simplify memory allocation ioctl (Laurent vivier)
- Keep control register shadows in sync (Rusty Russell)
- Retire invlpg (Rusty Russell)
- Expose get_cs_db_l_bits for kvm-lite (Rusty Russell)
- Fix network boot (Anthony Liguori)
- Round up memory in libkvm (Anthony Liguori)
- Fix option ROM loading (Anthony Liguori)
- Revert FACP ACPI change for Vista
- Fix segfault with -no-kvm
- lapic hrtimer external module compatibility (Qing He, me)
- improved (still imprefect) reboot
- better bios smp detection

Notes:
If you use the modules bundled with kvm-38, 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.

Hi,

What kernel is required to run this version?
I get the message
kvm: unknown symbol div64_64
when inserting this module in my ubuntu feisty 2.6.20-16-generic kernel. A quick google led me to believe this is only recently included in the kernel.

regards, Pelle

Looks like it's 2.6.22+. I'll release a kvm-39 with a backport for older kernels.

div64_32 is enough for us, so why not just use do_div?

I'm not sure div64_32 is enough, it can overflow in 4 seconds.

The patch seems to work, it compiles, inserts, and I can start a vm. I can't test properly until later.

Thanks!

Thanks much guys for kvm release38. I have an issue when booting a windows xp machine that I've been using with kvm for some time now. When I tried starting the windows xp machine my screen went blank and my xwindows session restarted itself. I then proceeded to try to start the machine again and my host was hung and had to reboot host.

I'm using the following parameters for starting my windows xp.

/usr/local/kvm/bin/qemu-system-x86_64 \
-hda winxp.img \
-m 400 \
-no-rtc \
-localtime \
-smb /home/hsolomon \
-no-reboot &

My kernel version is Linux localhost.localdomain 2.6.22.4-65.fc7 #1 SMP Tue

Aug 21 21:50:50 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux.

Reboot was improved in kvm-39, but not completely fixed. I'll nail it down in kvm-40 or kvm-41.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

You can reboot linux guests passing "reboot=b" on kernel command line. Don't know about win...
