Hello,
Is it possible to share a memory (a page perhaps) between the host and
guest? More precisely, could a host and guest share a memory-mapped
file? If one were crazy enough to want to do this, where should they
look first?
Thanks,
Cam

Hi,
I've been playing with VMGL and got it to work on KVM using two of the
three suggested setups 1) X forwarding and 2) VNC. However, with SDL it
doesn't work yet. This will require patching KVM/Qemu's SDL viewer.
Also, I haven't been able to get virtio networking going which is
necessary

Hi,
I get the following warning in the kernel messages:
kvm: emulating preempt notifiers; do not benchmark on this machine
Is this an accurate warning, should the machine not be used for
benchmarking KVM? or does it mean don't benchmark other applications on
the host?
Thanks,
Cam

I was able to grab the virtio sources. However, the make -C kernel
