Hey, if someone wants to be nice to get something, I'm OK with that, as long as they aren't jerks the rest of the time. It's better than the people who treat us like we're just servants at their beck and call.
I have a cloud-based virtual machine running Ubuntu and CentOS Linux server. It may or may not be virtualized. How do I determine what kind of virtualization technology (VMWARE/ KVM/ XEN/ VirtualBox/ Container/ lxc/Hyper-V etc.) a Linux guest system running on? How do I find out the virtualization type of a CentOS 7 Linux VPS?
