Virtualbox network troubleshooting

Fixing network issues in Virtualbox linux client Mac host

Set first network (provides internet access) like:

• ✓ Enable Network Adapter
• Attached to: NAT network, if the name shows blank then:
  • Vritualbox → Preferences → Network → NAT networks → Add new network → Name it NAT network
• Click Advanced → virtio-net → Allow VMs → ✓Cable Connected

Set Second network (provides SSH) like:

• ✓ Enable Network Adapter
• Attached to : Host-only adapter, and in name select vboxnet0. If there is none then create one like this:
  • File → Host network manager → Create → Name it vboxnet0 → ✓ Enable
  • Make sure to set IP address range to 192.168.56.1 and subnet to 255.255.255.0
• Click Advanced → Intel PRO/1000 MT Desktop (82540EM) → DENY → ✓Cable Connected

Then boot the VM and add the following lines to /etc/network/interfaces :

allow-hotplug eth1
iface eth1 inet dhcp

Debian doesn’t populate the eth1 interface therefore the system doesn’t work as intended by only configuring the parameters in the Virtualbox settings.
