I don't think you can clone your mac to run inside a VM. I've only seen directions to install a clean version of macOS. I did that on my X1E, and there are some basic guides on the net that make it fairly easy. I found Vmware Workstation to work well enough. You would then need to install/copy the data on your current mac over there.
In the end, I found running macOS in a VM to be waste of resources and disk space. I also had some significant stability issues, which I've not been able to pin down as the cause but I suspect it was Vmware. You see to run macOS on Vmware, you need to "unlock" the application. There's a number of unlockers, but those utilities alter and/or update various vmware DLLs. It seems awfully coincidental shortly after setting macOS/Vmware, I started incurring BSODs.
In the end, I wiped my drive and reinstalled windows, and I have no interest in reinstalling vmware and macOS on my X1E.
Why not get a cheap old mac to replace your 2010 machine? 2012 models are fairly inexpensive and will offer a years of service.
