Howdy,
I apologize for my ignorance for these reasons I didn't think it could have
been a resource issue:
1) Under Infrastructure -> hosts for the only host it says 64 CPU x 3.10 GHz.
2) The HV has 768GB of RAM and a 32 core 3100MHz CPU (which is 99.2GHz) [64
cores with Hyperthreading but I was only specifying 32 when creating the VM in
testing].
3) If I just tell it to put it on the only KVM hypervisor while specifying
Guest Network 2 instead of letting it decide the placement on its own it
creates the VM.
4) If I let it place the VM on it's own but I specify Guest Network 1 instead
of Guest Network 2 it places the VM on the only available host.
And yet this is what it says in the log:

Is there another place that is more authoritative for what the capacity of the
HV is than what the UI is saying?
I apologize for my obvious ignorance.
Thank you,

Hi Drew,
The log snippet you pasted doesn't really point to any actual error. It shows
the planner starting to look for a destination host, however the reason it
fails is probably further down in the logs, which would usually be along the
lines of "No suitable hosts found" or host/pool being skipped for insufficient
capacity. If you could share the rest of the management server logs
specifically for log id: 64143c60, maybe we can help point you in the right
direction. Also worth checking that your hosts have the capacity for this VM,
which is requesting 16 GB RAM and ~99 GHz of CPU.
Regards.
