Actually it should pause the VM - are you sure that KVM is "locking
up"?  If you run with SDL the window title says "[Stopped]" and you
can resume the VM with the "c" (continue) QEMU monitor command once
you've rectified the storage shortage.

Are you using libvirt (virsh/virt-manager)?

What makes you think that KVM is locked up?

How much CPU is the qemu-kvm process consuming?
