Attached to this email are two patches:
memstats-kernel-2.6.32-rc5.patch:
Applies to 2.6.32-rc5 which should be a capable-enough kernel for
testing and development.
memstats-qemu-0.12.1.patch:
Applies to qemu-0.12.1 which can be found here:
http://mirrors.igsobe.com/nongnu/qemu/qemu-0.12.1.tar.gz
Unfortunately, it is not trivial for me to port this work to 0.11.0 so
you will have to find a resolution to your BIOS woes first and then use
this version. Who knows, it might already be fixed in 0.12.1.
I tried with qemu-*kvm*-0.12.1.1, no memstats yet, but dynamically setting the
amount of memory now doesn't work at all. I'll try to isolate the problem, I
suspect it comes from qemu-kvm-0.12.1.1.
I can't use qemu-0.12.1:
$ ./configure --enable-kvm --disable-xen
#error Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS
NOTE: To enable KVM support, update your kernel to 2.6.29+ or install
recent kvm-kmod from http://sourceforge.net/projects/kvm.

From your next message I see that you've figured this out. The
wrapper
script will also be required when using the new qemu as well.
I can't use qemu-0.12.1:
$ ./configure --enable-kvm --disable-xen
#error Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS
NOTE: To enable KVM support, update your kernel to 2.6.29+ or install

ERROR
Try using the --kerneldir=PATH option to point configure at your
2.6.32.2 source.
