systat looks like this, during "normal" work:

After starting qemu until the the copyright message appears, the interrupts
are around these numbers. Don't know, if this is considered an interrupt storm.

"it takes ages" translated into numbers means, that from starting
qemu until the copyright messages it takes 1 min 10 sec. The rest
of to boot process needs another 20 seconds until the install propmt,
which I'd consider "normal". Maybe this is normal and I'm just too
impatient?
