Comment 1 Nisim Simsolo 2018-03-18 15:04:36 UTC
Sorry, I mistakenly opened the bug without entering description.

Description of problem:
While trying to remove USB passthrough device from VM, an engine NPE occurs and the devices failed to be removed:
2018-03-18 16:51:19,731+02 ERROR [org.ovirt.engine.core.bll.hostdev.RemoveVmHostDevicesCommand] (default task-27) [4c2992e6-4627-40ad-b23d-3a2e59b42166] Exception: java.lang.N
ullPointerException

This issue is not relevant for PCI device. 
Refreshing host capabilities is not solving this issue.
