Unable to start Genymotion due to network adapter

Question

Have installed and reinstalled Genymotion and VB for several times and now on the latest releases of both of them. When I try to start genymotion it fails and leaves a trace in logs:

[debug] [VBox] [findHostOnlyInterface] Looking for compatible host-only interface
[debug] [VBox] Call: ("list", "hostonlyifs")
[debug] [VBox] Return code: 0
[warning] [VBox] [getSavedHostOnlyInterface] Checking "VirtualBox Host-Only Ethernet Adapter" interface status (  QHostAddress( "192.168.56.150" )  )
[debug] [VBox] Empty interface name

[debug] [VBox] Call: ("hostonlyif", "create")
[debug] [VBox] Return code: 0
[debug] [VBox] [createHostOnlyInterface] Interface "VirtualBox Host-Only Ethernet Adapter #2" created with success

Have no idea why it doesn't like the existing one and what Empty interface name means. Then it tries to start a fresh one, but fails because by default it has a 0.0.0.0 IP.

[critical] [VBox] [createHostOnlyInterface] "VirtualBox Host-Only Ethernet Adapter #2" configuration is not valid. Subnet: "0.0.0" . Mask: "0.0.0.0"

[critical] VM Engine failed to load, state 4
[critical] Unable to find VM Engine. Plugin loading aborted.
[debug] [LogCollector] VM engine not available

It all looks like a conflict between VB and Genymotion. But hav no idea how to solve it. Already tried different versions for VB bridged driver, cleaning registry and reinstalling them both. No luck. Is there a way to get more detailed debug then in thoose loogs? Really interested why default network interface doesn't fit to VB.

Trying solution with deleting all net interfaces

I wonder what is checked during

[Genymotion] [warning] [VBox] [getSavedHostOnlyInterface] Checking "VirtualBox Host-Only Ethernet Adapter" interface status (  QHostAddress( "192.168.56.1" )  )

Answer 1

Yeah! I did it!
Due to my luck I found in the VB network connection settings a driver from Wireshark, added there automatically "NPCAP Packet Driver". After I removed it, everything started working like a charm!
