IMO, you can define a new flavor with values same as used to spawn the instance, except the memory (change it to your new value i.e. 3GB). You can then use the 'nova resize' command specifying the instance-id and the new flavor. You can then use 'nova resize-confirm' command to confirm the resize.

use virt-manager on the compute node, if you're using libvirt, virsh edit <instace-name> may also help

Can you help with this problem?
