Since kvm_stat is part of the Ubuntu package linux-tools and packages are 
affected by the feature freeze, this cannot be processed right now, since we 
are at the end of the 21.04 cycle, and we have to wait until 21.04 is released.
Once 21.04 is out this can be picked up again and a service release update 
(SRU) process can be started.

Title:
  [UBUNTU 21.04] tools/kvm_stat: Add restart delay

Status in Ubuntu on IBM z Systems:

Bug description:
  Description:   tools/kvm_stat: Add restart delay
  Symptom:       If the kvm service is enabled and the system rebooted,
                 Systemd's initial attempt to start the kvm unit file may
                 fail in case the kvm module is not loaded. However, once the
                 kvm module is loaded, the service is _not_ started.
  Problem:       Since the unit file does not specify a delay for the retries,
                 Systemd restarts with a minimum delay a number of times
                 before giving up and disabling the service. Which means a
                 subsequent kvm module load will have kvm running without
                 monitoring.
  Solution:      Add an appropriate delay in the unit file.
  Reproduction:  (1) Enable the kvm service via systemctl
                 (2) Reboot
                 (3) Verify that the kvm module is not loaded & kvm service
                     not running
                 (4) Load the kvm module via 'modprobe kvm'
                 (5) Verify that the kvm service came up within the next
                     minute.
  Preventive:    yes

  Just use the attached patch and you're good!
