Phillip,
Since you didn't specified hypervisor I presume you kept in mind - KVM
isn't it ? I have had FreeBSD 10.1 guests running there for a short while, but
was not satisfied with performance. GENERIC kernel contains support for
differen hypervisor types, but it seems this support is not equal. At
XenServer I got much better numbers running guests in PVHVM mode. There is
also non-official patches for kernel to allow unmapped IO that makes it even
faster. So, I would say, It all depends where are you running your guest VM.
KVM, XenServer, VmWare, Hyper-V -- it all be different. Cloudstack, as Ahmad
said, has nothing to do with it.
BR,
Vadim.

Jeff,
AFAIK paravirtualisation is no longer considered the way to go (unless you lack
virt support in CPU).
I always prefer Other/Misc profiles in Xenserver, gives me a more "proper" OS,
even when using linux. BTW most linux distros will enable paravirt drivers to
access disk and network.
Even Amazon recommends HVM: "for the best performance, we recommend that you
use current generation instance types and HVM AMIs when you launch new
instances.".
