Hi and welcome!  CloudStack can be used with Citrix XenDesktop and XenApp to provide VDI services
for users. It’s covered in the XenDesktop install/setup docs (just replace CloudPlatform
with CloudStack)

If you mean for VDI, XenDesktop can manage this once connected to CloudStack. If you mean
outside of that setup, the phrase you’re looking for is “autoscaling.” Currently it
works with either NetScaler load balancers or XenServer virtualization.

Yep - XenDesktop will do that for ya. :)
