I see many different types of servers but can't find any information about hypervisors, are they all using the same (KVM) or is there openvz and xen vm's available too. And what about dedicated and bare metal servers, how do they work?
KVM (Kernel Virtual Machine) is the only hypervisor we use and it's available in all regions. It's open source, lightweight and can utilize nearly all physical resources on a host node. KVM is also used on dedicated and bare metal servers with 1:1 mapping to allow quick and automated installations and most important to utilize the full physical machine.
