Well, we had QEMU 2 until December 2018, so it's not really that far
behind for a "stable model" distro like CentOS. QEMU has been
incrementing their version number a lot lately.

Josh, here is a link to the manual instructions from when we were using
QEMU 2:

https://git.savannah.gnu.org/cgit/guix.git/tree/doc/guix.texi?id=6512b96570f79c6d230363dfe2adbd159c7861f5#n21529

Can you try that? I would add more RAM. If it doesn't work, can you try
consulting the man page for your QEMU to see how the commands might
differ?
