On the pve2 node, I will create the EVE-NG VM by right clicking on pve2. I named it EVE-NG-2.
To upload the ISO under the OS tab and under the System tab, use the default.
On the Disk tab , I allocate 450Gb.
On the CPU tab, it is important that the Type be set to host. I also set CPU Cores to 4. Moving to the Memory tab, I allocated 16Gb. The Network Tab can left using the default but I did uncheck the Firewall option.
Finally, you will see the Confirm Tab where you can change any of the prior settings.
