Should they be loaded nowadays?Not on the host AFAIK. The disk format used is vmdk with no caching and native mode.The io is 100% in windows task manager performing less than 1MB/s Any clues?What are the figures from the host? What is qemu doing and what are the other processes and devices doing?What is the best way to find this out?
{,a,h}top should do for the initial runs, just to see if the block layer
is busy or the CPU is busy or something else is blocking it
