All net cables disconnected between r112052 and r112114

[socratis]

I just opened ticket #16260 : OSX guests: all net cables disconnected between r112052 and r112114. I'm simply going to re-post the description here for the searchers, other users and finally (and hopefully) to see if anyone has any ideas...

Most of my VMs have 4 network cards, 3 of them connected:

1. HostOnly, in the 192.168.20.0/24 range.
2. VBoxIntNet, in the 192.168.30.0/24 range.
3. Bridged, with my Airport card, usually cable=disconnected.
4. VBoxNATNet, in the 192.168.40.0/24 range, usually disconnected for Windows guests.

Starting with rev. 112114, all my network connections only on OSX guests are showing that the cable is not connected in the guest, i.e. there's no network whatsoever. Reverting to rev. 112052 magically connects the cables that were already connected in the configuration, i.e. 3/4. I tried rev. 112124 and that fails as well.

I changed the network adapters, since the OSX guests are the only ones using the "Intel PRO/1000 MT Server", but it made no difference.

All my other guests, (Windows, Ubuntu, Manjaro, Fedora, Mint, you name it) do not have that problem. Only the OSX guests.

From a 10.8 guest (for which I'll include the logs), excerpt of "ifconfig" for NIC1 (HostOnly), rev. 112052:

Code: Select all

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
	ether 08:00:27:44:24:b5 
	inet6 fe80::a00:27ff:fe44:24b5%en0 prefixlen 64 scopeid 0x4 
	inet 192.168.20.101 netmask 0xffffff00 broadcast 192.168.20.255
	media: autoselect (1000baseT <full-duplex>)
	status: active

and excerpt of "ifconfig" for NIC1 (HostOnly), rev. 112114:

Code: Select all

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>
	ether 08:00:27:44:24:b5 
	media: autoselect (<unknown type>)
	status: inactive

I have tried all of my OSX VMs, from 10.5 to 10.12, with the same results.

In the ticket, I've included the following files (I don't want to re-attach them and duplicate them):

• ifconfig 112052.txt
• ifconfig 112114.txt
• VBox-10.8-r112052.log
• VBox-10.8-r112114.log
• Mac OS X 10.8.vbox
• Mac OS X 10.8-Startup.png

If you guys need anything else, please let me know...

Damn, am I the only one that uses the testbuilds on a Mac?

Anyway, I don't know what they did, but with r112223 everything returned back to normal. Thanks...
And, no, I wasn't seeing things
