The way recommended by QEMU developers is to use KVM, purchasing new 
hardware that supports KVM if necessary, in which case you won't need 
to use much of QEMU.  Good performance on other hardware requires the 
kernel module kqemu.  The QEMU developers have deprecated kqemu and are 
removing it from the next version (.12 IIRC), but you can currently 
still use kqemu if you build QEMU with kqemu enabled.

I have just switched from QEMU to VirtualBox (with RPMFusion enabled, 
`yum installVirtualBox-OSE`) and can recommend it, unless your VM needs 
access to your actual USB devices or needs to be controlled remotely, 
as those features are not open source.  I was able to configure 
VirtualBox to use the same disk partition (which appears as a 
partitioned disk itself) as with QEMU, and network setup was much 
easier and didn't require any equivalent to the custom scripts I wrote 
for QEMU.
