How to Know your VPS host (cloud host) with what virtual technology to achieve?

Recently got a day. Cloud Hosting (VPS) just want to know what virtual technology it is implemented with? All I know is that KVM is a lot more.

I started using the command: dmesg, to view the system's boot information, I saw the following information:

[ 0.000000] dmi: xen hvm domu, bios  4.2.AMAZON 12/07/2015[ 0.000000] HYPERVISOR DETECTED: XEN HVM[ 0.000000]  xen version 4.2. [ 0.000000] xen platform pci: i/o protocol version 1[ 0.000000]  netfront and the xen platform pci driver have been compiled  for this kernel: unplug emulated nics. [ 0.000000] blkfront and the xen platform pci driver have  Been compiled for this kernel: unplug emulated disks. You might have to change the root devicefrom /dev/hd[a-d] to  /DEV/XVD[A-D] 

From here I know that this cloud host is implemented using Xen virtual technology . There's also a Xen directory under this /proc/ directory, so I'm more certain.

In addition, I also found on the internet on how to know the host VPS is the use of what technology to achieve the article, the introduction of the method is more, the link is as follows:
