The current code is geared towards using a user-mode (A)PIC. This patch adds
an irqdevice abstraction, and implements a userint model to handle the
duties of the original code. Later, we can develop other irqdevice models
to handle objects like LAPIC, IOAPIC, i8259,

The VCPU executes synchronously w.r.t. userspace today, and therefore

This is overly abstracted. It's not like you can (on real hardware)
wire your own lapic and plug it into the processor. It's well defined,
and there are just three

The following is my patch series for adding in-kernel APIC support. It
supports three levels of dynamic configuration (via a new ioctl):
* level 0 = (default) compatiblity mode (everything in userspace)
* level 1 = LAPIC in kernel, IOAPIC/i8259 in userspace

Hi,
I made an mknod myself now, did a cat of /sys/class/misc/kvm/dev

and did a

everything OK now
how come I dont have the /dev automatically ?
udevtrigger didn't help, pgrep udevd showed the pid of udevd... so it

Is this the reboot that's part of the install? If so, it's
kind-of-expected.
KVM shadow page tables are always in pae mode, regardless of the guest
setting. This means that a guest pde (mapping 4MB of memory) is mapped
to two shadow pdes (mapping 2MB each).
When the guest writes to a pte or pde, we intercept the write and emulate it.
We also remove any shadowed mappings
PAGE_MASK is an unsigned long, so using it to mask physical addresses on
i386 (which are 64-bit wide) leads to truncation. This can result in
page-private of unrelated memory pages being modified, with disasterous
results.
Fix by not using PAGE_MASK for physical addresses; instead calculate

Interestingly, I still get the lost interrupts messages if I leave the
max-user-freq at the bootup default of 64. Running XP under kvm fresh after a
reboot:

Ok, so running as root allows qemu to ignore /proc/sys/dev/rtc/max-user-freq
and increase the frequency to 1024Hz anyway.
Running as a user means I get this message from qemu again:

I have recently tried to install XP 64 bit SP1 on KVM 16.
But Windows setup buzzed on text mode and screen: Setup is starting Windows.
Xp 32 bit runs on KVM 16 without any problems.
Does KVM support XP 64 bit?
Thank you very much!
Hi all,
I've been toying around with a benchmark suite for virtualization, and
I've just added kvm support. You can download the source tarball
straight from the mercurial repo:
