Is the performance you've measured with virt-who-0.14-1.el7 sufficient or should we try to improve it further? The rebased version will get to RHEL-7.2. William, thanks for confirmation. It looks that new version of virt-who has sufficient performance. we test the virt-who performance with virt-who-0.14-4.el7.noarch, no performance issue found. 10 hosts x 100 guests = 1000 guests The cpu and memory usage is acceptable. Details, please refer to: https://mojo.redhat.com/docs/DOC-1044700 Alan, the change is not easy to backport into RHEL-7.1 virt-who package. The whole part touching VMWare hypervisor is rewritten and it requires changes all over the codebase. I think it would be better to provide the same virt-who package that will be part of RHEL-7.2 to the customer now. This version is thoroughly tested by QE team. Do you agree to provide latest virt-who package (virt-who-0.14-9.el7) to the customer as hotfix for this issue? I can rebuild it and tag it as hotfix if necessary. Hotfix build done: https://brewweb.devel.redhat.com/taskinfo?taskID=9923102 Let me know if you need anything else.
