This should be feasible the same as with a physical machine: Once you provided a larger (virtual) disk (i.e. by moving to a larger Dom0 partition), the next DomU reboot should pick up the larger sized vDisk. It then depends on the specifics of your installation if i.e. moving existing partitions, extending PVs or something else is required to increase the effective size of the root partition.

Situations like this are the main reason for me to set up DomUs with LVM... add another virtual disk, create the PV, add the PV to the volume group, resize your LV and then the partition. All this can even be done online.
