OK, I've tried both methods, but ran into some problems. It's likely it's just something I'm doing wrong.
When I tried to install a new VM, here's the output I get after reboot, and firing up the new VM with Qemu: (sorry for the wall of text!)
Warning. Could not determine the CPU Family.model name : QEMU Virtual CPU version 2.4.0

When I tried to use my existing 15.3 exosvm.vmdk image, and put the exospc-16.1.2.14.xos image in a tftp server (Debian Jessie w/tftpd-hpa), "download image exospc-16.1.2.14.xos secondary" keeps giving this error:
Downloading to SwitchError: Failed to download image - tftp: sendto: Network is unreachable
Both VMs have IP reachability (same subnet) to one another (they're literally cross-connected, and the only devices on the "network") , and the tftpd-hpa server has no restrictions, so I'm not sure what I'm doing wrong with this, either.
Any help pointing out what I'm doing wrong would be greatly appreciated!
