For the first part, yes it's good. Give it 3 cores and at least 6GB of memory (~6144MB, but 6028 will be fine), but you can also give it 9GB as others suggested, as you have plenty and won't miss it. :)
For the second part, also yes. Open 3 terminal windows, and use separate commands in each.
Now 3 recon processes will finish in about the same time like did only one before.

Thank you guys for all the great information! Now I only have a few questions.... I realized that my computer has 4 cores... So based on your suggestions, if I assign 3 cores for my Freesurfer virtual machine, should I change the # of processors to 3 in my freesurfer virtual machine's "Setting "?
Base Memory:
6028 MB
Processors:
3
Boot Order:
Floppy, CD/DVD-ROM, Hard Disk
Acceleration:
VT-x/AMD-V, Nested Paging Is this correct? Also, if I want to run multiple freesurfer recon-all in one virtual machine, should I just open several terminals, and enter in separate commands? If I understand correctly...
Thanks Again! Catherine

Hi Catherine
it depends on how many processors you have. If you have multiple CPUs you should be fine, although you'll need at least 2G/process if not 3.

Dear All,
I was wondering if I can run several freesurfers in my virtualbox
simultaneously by setting up several virtual machines...my computer has 16G RAM and it's Windows 7 64-bit.
Would working multiple freesurfers at the same time slow down the
calculations?
Moreover, I was wondering if my computer could afford these loads...
Thanks Catherine
