Screen shot of said VM Manager?
Also, you will miss ESXi if you ever need to configure VLANs .
As far as creating and editing VMs/properties, it's good and the vnc integration is nice as vsphere is becoming less and less functional. Monitoring is a whole other can of worms, which is not currently addressed and the vlan thing is a let down too. HOWEVER none of that really applies to me for home use and couldn't care less.
The real bummer is that the FIO cards I was using for vmdk/virtual cache disk don't work on slackware so I had to replace them with a standard SSD for my cache/domain storage. But with that said, i like having all 8 cores accessible to unaid and my docker containers without all the io-wait associated with having a large core count VM.
