3.2.10 issue:Host Only Adapter : Cannot ping guest from host

Post by onions »

I was an happy camper running virtual box 3.2.8 with host running Windows 7 64 bit & Guest OS being windows 2008 R2.I had 2 network adapters in this VM
1)Intel PRO/1000 MT Desktop (Host-only adapter, 'VirtualBox Host-Only Ethernet Adapter') (192.168.56.101)
2)Intel PRO/1000 MT Desktop (NAT) (10.0.3.15)
With the above setup, I could able to seamlessly access Guest IP from host. for ex: ping 192.168.56.101

Yesterday I updated to 3.2.10 virtual box & I could no longer ping the Guest from host. Also updated to 3.2.10 guest additions, but
still cannot ping guest from host. Not sure what is the issue here. I have re-configured adapters, restarted both guest & host multiple times, but
still cannot ping guest from host. The windows firewall is off on both Guest & Host.

How can we resolve this ? Is anyone experiencing the same issue ?

Recheck the network settings for the firewall and the IP address. It might have gotten a different IP and the firewall might have changed because of that. The network type will be detected as public network for the Host-Only network. This has to be explicitly turned off in the firewall.

Gotcha.. The firewall is ON for public network & I could see why Host cannot reach the guest. Out of desperation I reverted back to 3.2.8 & everything is fine,
But I sure will try this when I update to 3.2.10 . Thanks Moderator.

I had the same problem with a Ubuntu guest on VirtualBox 3.2.10, tried various tricks with the Windows 7 firewall (from making it not monitor VirtualBox Host Only adapter to switching the fw off completely) and nothing helped -- no ping, no http, no anything to the guest. The solution which worked was to downgrade to 3.2.8...

Similar problem here. After upgrade to 3.2.10 when I wake up host computer from sleep, the IP address of host-only adapter gets lost and is set to 169.254.151.146 or so. I have to manually set adapter to DHCP and then to desired static 10.10.10.1. After that network works again, till next sleep. Annoying.
