Import GNS3 VM into PVE:

Start from VMWare ESXI image (ova / zip)
Copy to a location on the Proxmox system (i.e. a network share or /root)
cd to the directory the ova is in

# Extract zip it came in
unzip GNS3*.zip
# Resulting file in my case was called `GNS3 VM.ova' (with a space in the name!)
# Extract OVA (this is itself a zip)
tar -xvf 'GNS3 VM.ova'
# Import to VM ID 590 in Proxmox (just an example)
qm importovf 590 "GNS3 VM.ovf" local-zfs
