virt-who one shot gives the correct output but running a virt-who service fails to map the correct hyperviosr-guest.

Solution Verified - Updated

Environment

  • Red Hat Satellite 6.3.

Issue

  • When running a virt-who one shot specifying the name of one configuration file gives the correct mapping of hypervisors to guests, but if only virt-who service is running or not specified the name, it returns the wrong data/mapping.

  • Output when file name specified: 

# virt-who -odc config1.conf
2019-04-25 14:44:06,269 [virtwho.destination_-6565174713917789106 INFO] MainProcess(43687):Thread-3 @virt.py:_send_data:598 - Hosts-to-guests mapping for config "config1.conf": 5 hypervisors and 824 guests found
  • Output when the file name is not specified: 
# virt-who -od
2019-04-25 14:42:25,356 [virtwho.destination_-6565174713917789106 INFO] MainProcess(42925):Thread-9 @virt.py:_send_data:598 - Hosts-to-guests mapping for config "config1.conf": 2 hypervisors and 7 guests found

Resolution

  • It is observed that when having multiple virt-who configuration files, one must have some parameters unique per file.
  • Make sure all the files have a diferent header specified. No two files can have the same header. 
# vi /etc/virt-who.d/virt-who.conf

       [vmware]    <====== Like all other parameters, this should be unique to every file.
       type=esx
       server=vCenter(FQDN/IP)
       username=vCenter_Username
       password=vCenter_Password
       owner=org ID (From the Command # subscription-manager identity)
       env=Library
       hypervisor_id=hostname

Root Cause

  • When running virt-who one shot without specifying the file name, it reads all the config files and conflicts between two similar headers and returns wrong data.
