Host is running: 2.6.31.4
QEMU PC emulator version 0.10.50 (qemu-kvm-devel-88)
Please update to last version and repeat. kvm-88 is ancient and
_lots_ of stuff fixed and changed since that time, I doubt anyone
here will try to dig into kvm-88 problems.
Current kvm is qemu-kvm-0.12.2, released yesterday.
Sorry about that, I didn't realize 88 was so far behind.
Upgrading to qemu-kvm-0.12.2 did solve my IO problems.
Found these build issues if anyone is interested:
"--enable-io-thread" gave me:

And "--enable-cap-kvm-pit" is defined if you look at "--help", but does
not exist if you try to use it!?
# ./configure --enable-cap-kvm-pit | grep cap-kvm-pit
ERROR: unknown option --enable-cap-kvm-pit
