There's more basic build problems with the kernel at the head of 
development, but that doesn't seem related to kvm.

Thanks for the info.  However, "-serial stdio" doesn't seem to work.  I get:


root@ebony:~# ./qemu-system-ppcemb --enable-kvm -nographic -m 128 -M 
bamboo -kernel uImage.bamboo -L . -append "" -m 64 -serial stdio
chardev: opening backend "stdio" failed
qemu: could not open serial device 'stdio': Success


I'm using the qemu at git://git.savannah.nongnu.org/qemu.git, not the 
one at git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git, because the 
latter wouldn't build.  I suppose those are the build problems you speak 
of.  I'll see if I can get the latter working.

Thanks a bunch!
