Hello dibl,
I still remember how much I depended on vmware's industrial strength when i was running a business IT with 300 virtual servers in 2010. The enormous complexity of building that private cloud was astonishing.
Now I've read that vmware tools were deprecated for linux in favour of open-vm-tools.
KVM and Openstack are a huge success, and even for desktop usage vbox and qemu are doing well.
Yes, today i'm quite happy with opensource solutions.
greetings
