Failed to execute createHOMObj for the Setup : No GuestOS section in XML file

Hi

I am executing VAAI NAS certification test cases. All test cases are passed except "StressIOMultiLazyCloningSameVolume".

This test case require One NAS volume with two virtual machines and IOzone must be installed on the virtual machines.

I created two VM and in each VM install IOZONE. I also checked DNS configuration of host(FQDN name entry) in vCenter server and workbench.

When i executing this case i got following error.

Failed to execute processSetup for the Setup : Failed to execute handleHostVMObj for the Setup : Failed to execute createVMObj for the Setup : Failed to execute createHOMObj for the Setup : No GuestOS section in XML file.

I also attached my log file
