Hello,
Is it possible to share a memory (a page perhaps) between the host and

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:

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,

You do not need to make -C kernel sync with kvm-tarballs.
