I've been using the vexpress image with QEMU to try to track down some ARM-specific problems in two of my packages. The VM was unbearably slow at first (by which I mean that a simple "yum upgrade" took over 6 hours), until I changed:
-sd "$IMAGE" to: -drive if=sd,cache=writeback,file="$IMAGE" in boot-vexpress and boot-vexpress+x. I'm well aware of the danger of using writeback, but ... it's a VM. With the script as shipped, my hard drive light was on constantly, and the entire host was slowed down dramatically due to insufficient disk bandwidth. With writeback on, I can re-create the VM and reinstall the packages of interest in very little time, certainly less than even simple operations were taking with write-through on. Is there some reason why changing the scripts to use writeback would not be a good idea?
