You are going in the right direction but I think QXL might be doing
other allocations other than the main vga videoram.
Now that I think about it, another way around the memory allocation
problem would be to add "maxmem=MEMORY" in your VM config file, where
MEMORY is equal to the amount of memory you assign to the VM plus the
videram.

So if you have:

memory=1024

then you could try adding:

maxmem=1088
