Cirrus driver is not available for windows 7, support of it is near 
abandonment in upstream if I remember good what I read one year ago (or 
more) in qemu-devel, is better use stdvga instead in windows >=vista.
A had also strange graphic and performance problem with cirrus on 
windows 7 2-3 years ago, since then I have not set the cirrus on vm 
windows 7.
Try to vga="stdvga"

Years ago on my tests system with few ram I tried to decrease ram as 
possible but I saw that with windows 7 (even if 32 bit) with < 1 gb made 
occasional problems that wasted my tests.
About performance for run tests (after windows install even if basic) 2 
gb of ram at least is needed for don't waste large amount of time on 
massive numbers of tests.
I saw many occasional windows tests fail on "[Xen-devel] [xen-unstable 
test] ....: regressions - FAIL" that I was unable to reproduce doing 
same tests (windows install, shutdown, save/restore) and that blocked 
push for days even if I not saw "real bug/regression" was found.
If these are only caused by "bad" xl cfg values rare to find on real 
users domUs I think is bad and should be improved.
