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 Advancedvirtio-netAllow 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 and subnet to
  • Click AdvancedIntel 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.
