The 'mem-set' command merely sets a *target value* for a guest, it does not attempt to immediately allocate it. The balloon driver in the guest will try to allocate memory from the hypervisor to meet this target - if there's not enough available, it will retry (pretty much forever) until it can get enough. In your case all your memory is assigned to Dom0 so there's nothing for the HV to give to DomU. You need to lower the allocation for Dom0 manually. This is explicitly not done automatically. |
