Subject: [PATCH] kvm: sending std output to dev/null to prevent garbage output
 (#4123)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When scripts/vm/hypervisor/kvm/kvmvmactivity.sh is called with an incorrect file name, an error is printed which is then interpreted as output from the script.

When an incorrect file name is passed the script prints out:

stat: cannot stat ‘b51d7336-d964-44ee-be60-bf62783dabc’: No such file or directory
=====> DEAD <======
The KVMHAVMActivityChecker.java checkingHB() process is expecting just
=====> DEAD <======
but gets the unexpected error message and interprets the file as alive.
