    I have also run into this caveat. I am running 13.1.1.4 on VMware Workstation 15 on Fedora 29 Linux kernel 5.0.4

     

    Thanks to the help of F5 FSE, I have managed to resolve it by adding the following DB variables on each VM on WMware Workstation 15.x:

     

    tmsh modify /sys db tm.tcplargereceiveoffload value disable

     

    tmsh modify /sys db tm.tcpsegmentationoffload value disable

     

     

    It appears that WMware loses packets when offload is enabled.

I can partially answer this question. I was able to successfully configure DSC for VE v13.0.0 but with LAB license. Each VE required 8 GB of RAM and 4 CPUs (ESXi environment). Not sure if this works for Trial or Evaluation licenses as far I didn't manage to configure DSC with 4 GB of RAM and 2 CPUs per VE using both of those license types (VMware Fusion environment).
