    This really is just an FYI post incase anyone searches for an issue like this.

    I recently decided to migrate my HyperV infrasture to my ESXi (6.7) server to consolidate my server rack. Including rewiring my entire network. The VM in question is a Plex media server running on RHEL 7.6 on 2012 HyperV. All setting were default when I created the VM, nothing special. I tried to use the VMware converter software but when I booted the VM on the ESX/vSphere server, the VM would fail to detect a bootable VHD and boot the the EFI firmware. After multiple attempts, changing a few options in the HyperV config each time, I decided to think outside the box. I managed to get the VM to boot but it would fail to detect LVMs, despite following the RH solution (Kernel panic on boot following "dracut Warning: LVM rootvg/rootlv not found" - Red Hat Customer Portal).

    At this point I was convinced that the conversion was unable to account for some settings.

    The final solution:

    Convert the HyperV VM to a VMware Workstation export.
    Remove all drives from the VM
    Add the VMDK as an IDE hard drive.
    *For compatability, set the proper guest operating system (RHEL 7 64-bit)
    Upgrade VM compatability to Workstation 14/ESXi 6.7
    Connect VMware Workstation to the ESXi/vSphere server and upload the VM
    On the ESXi/vSphere server, remove the NICs currently on the VM (they are incompatible) and add a new NIC (VMXNET3 preferably)
    Power on the VM and expect some services to fail.
    Determine the interface name and use NMTUI to add and configure the connection.

    This took almost 3 hours for me to figure out but hopefully it helps someone.
