EVE-NG QEMU based nodes are not starting

Setup:Dell PowerEdge R620 128GB Ram 12 Core server. Vmware ESXI 6.5 Based setup: 1 VM for EVE-NG: 500GB SSD + 32 GB allocated RAM. 2nd VM for Windows Server 2016: 100GB HDD + 16 GB RAM. On Windows client, I can access the EVE-NG via Firefox and Putty. I have tried cisco Dynamips images and nodes are starting (I can telnet with putty and change config)

When I try to created nodes based on Qemu Images(Cisco, Aruba, Paloalto, etc), the nodes do not start. I have followed the guidelines for qcow2 names as well as checked multiple sources. I have also edited the node and tried to play with all possible settings. I have reinstalled the EVE-NG on ESXi as well but the issue remains the same.

Thanks a lot for your help and support.

This helped me a bit. I was using mac and struggling to get the consoles up. Posting the below steps in case it helps someone like me:

1. Shut down the VM using command shutdown -h now
2. Go to the VM settings
3. Click Advanced -> Check "Remote display over VNC"
4. Check Enable IOMMU in this virtual machine
