VyOS router starts, then immediately stops

[freefor]

I'm running Eve-ng in VMware Fusion (4 processor cores, 4 GB RAM, 40 GB HDD). I'm trying to run a QEMU VyOS image. I created a VM for VyOS with a single VMDK file, moved it to the Eve-ng system, converted to a qcow2 via the '/opt/qemu/bin/qemu-img convert -f vmdk -O qcow2' command and then ran '/opt/unetlab/wrappers/unl_wrapper -a fixpermissions' command. The qcow2 file has been moved to /opt/unetlab/addons/qemu/vyos. I then add a VyOS node in Eve-ng and hit Start. It'll light up for a couple seconds, then go dark again.
I'm very new to Eve-ng, but I can't seem to find anything that gives an indication what's going on. There doesn't seem to be much of an indicator in the log files as to what is going on. Can anyone help advise me on this matter?

please check on EVE cli

kvm-ok

if it will say that KVM is not enabled, you have to check VM CPU settings and enable Intel VT-X

when Intel VT-X is enabled, then output of kvm-ok must be:

root@eve-ng:~# kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
root@eve-ng:~#

You need to enable virtualization in bios and VM if you're using a vm
