Crash at startup: VERR_INTNET_FLT_IF_NOT_FOUND

[papin]

See my first post (Ticket #12787: "upg 4.3.6 -> 4.3.8 modifies VM settings") for the full story.

Host: XP Pro SP3

Guest: XP Pro SP3

Current version: 4.3.6-91406

Guest's network settings:

• Adapter 1:
  • enabled
  • Attached to: "NAT"
  • Adapter type: "PCnet-FAST III (Am79C973)"
  • Promiscuous mode: disabled (greyed out)

• Adapter 2:
  • enabled
  • Attached to: "Bridged Adapter"
    • Name: "Intel(R) Wifi Wireless Link 4965AGN"
  • Adapter type: "PCnet-FAST III (Am79C973)"
  • Promiscuous mode: "Deny"

What's happening?

Upon first start of the VM right after undergoing the upgrade, the VM cannot start because VirtualBox complains about the network settings. See attachment "NAT error.png".

Steps to reproduce

1. Install 4.3.8-92456 over current version (no uninstall)
2. Update .vbox-extpack (menu File/Preferences)
3. Start the VM

The problem is with the bridged adapter, not the NAT adapter.

Please reopen if still relevant. In that case please attach the VBox.log file as well as the output of

VBoxManage list bridgedifs
