I need to create a virtual cube out of two cubes. Both containing huge
volumes of data. Will the virtual cube have any performance problems when
accessing data in my report?

Nope.

Use them all the time.

One of the advantages is that you can put calc measures in this and then you
don't need to process the physical cubes to see the results.

But lots of other things matter ....

Large flat dimensions, Lots of non empty combinations etc...
