Doc Text: |
In some scenarios, the PCI address of a hotplugged SR-IOV vNIC was overwritten by an empty value, and as a result, the NIC name in the virtual machine was changed following a reboot. In this release, the vNIC PCI address is stored in the database and the NIC name persists following a virtual machine reboot.

Just from reading the source code, I expect that bug 1703112 will be reproducible by creating a before_get_caps hook on the host. The hook should just sleep for a short time between 1 to 15 seconds. I hope this would change the timing of the threads in Engine in a way that triggers the bug.

Maybe a high VdsRefreshRate would work, too.
