No. Redefining virtual memory causes a virtual system reset. It

Well, not quite true.
You could add more swap.
And if you added swap-on-VDISK, it'd really live in memory (assuming
no memory pressure on the Linux guest).
So, define VDISK to the machine at some address. Bring it online
through the /sys/bus/ccw interface. mkswap to format it. swapon /dev/
dasdt1 (or whatever), and you should have a machine able to swap to
your new VFB-512 disk.
