Currently not, but there is an [open issue](https://github.com/OpenNebula/one/issues/906) for this feature.

It should be implemented for all of the hypervisors. [Check vCenter](https://github.com/OpenNebula/one/issues/1660) as well.

it would be really nice, we had mem hot resize as a widespread default feature since Xen2 - that is 2005. Always feels wrong when I have to have downtime for this.  
(And it’s embarrassing in face of users - quite)
