VM

hi,
i have:

hostnamectl
Static hostname: test1
Icon name: computer-vm
Chassis: vm
Machine ID: ccfd9cda15204235be08f87f0daf1a84
Boot ID: fb4eab074b7c4538be6f8f45b16a94c6
Virtualization: xen
Operating System: Red Hat Enterprise Linux Server 7.5 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.5:GA:server
Kernel: Linux 3.10.0-862.11.6.el7.x86_64
Architecture: x86-64

and
hostnamectl
Static hostname: testy
Icon name: computer-vm
Chassis: vm
Machine ID: ccfd9cda15204235be08f87f0daf1a84
Boot ID: 84a9d35bca52411a87e3f635782fc7e3
Virtualization: xen
Operating System: Red Hat Enterprise Linux Server 7.5 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.5:GA:server
Kernel: Linux 3.10.0-862.11.6.el7.x86_64

From the above can i say that 2 VMs run on the same or different host?
How can i find if 2 VMs with rhel run on same host or on a different host?
dmesg maybe give some information.
