Hello, This week I was working on restoring network interface after thawing a vkernel from a checkpoint. What I have to do was to reopen appropriate device file, bring it up then either set TAP address or tie it to a bridge. In order to be able to do all this I had to store some information originally discarded once network interfaces are set up. Mainly TAP device fle name and either TAP address or bridge file name were needed. Finally, vke_softc structure had to be updated with new TAP device file descriptor and TAP device unit.
