Network issues in VBox 5.1.8

Description (last modified by )
I'm running 64bit VBox 5.1.8 with a Win7 guest on a Mageia 5 host.
After upgrading to 5.1.8, the virtual network will not time out in the Win7 guest. In other words, any app that tries to access any unavailable network resource freezes indefinitely. The only solution is to uncheck/deactivate the network device via Devices > Network > Adapter 1, which immediately allows the app to wake up and complain about the network being unavailable.
Downgrading to 5.0.16 fixes this network problem.
I also tested this on the latest build (5.1.9 r111957) which has the same problem.
Specific examples: an emulator for a mainframe, Notepad++ with a file open that lives on the network at work, xplorer2 with a network folder open. All of these are completely frozen while the network is unavailable.

Your log file lists a second, host-only adapter in the guest, but I don't see anything about it in the guest IP configuration you provided.
comment:5 by , 7 years ago
I did not notice that the host-only adapter was disabled in the guest. Enabling it fixed this issue in 5.1.9 r111957.
I'm guessing that the adapter was disabled during the removal of 5.1.8 or the installation of 5.1.9. I know I did not disable it manually.
Since the network resources being connected to are not on the host, it seems odd to me that enabling the host-only adapter would fix the problem, but it did.
Thanks for your assistance. As far as I am concerned, this ticket can be closed.
The network configuration I asked for was the configuration of the guest, not that of the host.
Do you mean when the network on the host is unavailable?
