Check whether the Linux instance can be a hypervisor

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest KVM guest

An instance of Linux on IBM® Z must have the SIE (Start Interpretive Execution) capability to be able to act as a hypervisor, such as a KVM host.

Procedure

  1. Issue the following command to find out whether you can operate your Linux instance as a hypervisor. 
    # cat /proc/cpuinfo
vendor_id : IBM/S390
# processors : 1
bogomips per cpu: 14367.00
features : esan3 zarch stfle msa ldisp eimm dfp edat etf3eh
highgprs sie
cache0 : level=1 type=Data scope=Private size=128K
...
  2. Examine the features line in the command output. If the list of features includes sie, the Linux instance can be a hypervisor.
    The Linux instance of the example can be a hypervisor.
