host-only networking debug (10.9.4 and centos)

[ethan412]

I cannot get host-only networking to work from host to guest or guest to host using e.g. ping, netcat or ssh. Sshing fails timing out. No packets are seen when starting wireshark on the host interface vboxnet0. I can ping my guest ip (192.168.33.10) from the guest, but cannot ping my host vboxnet0 ip (192.168.33.1) from the host. Any thoughts on what I can do to debug this? Does the configuration below look reasonable?

Host and guest firewalls are turned off.

The ip address is not the default one used for VirtualBox host-only. Did you change it? Also is DHCP set properly and are you using it or static?

I setup the vm using vagrant

Code: Select all

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "puppetlabs/centos-6.5-64-puppet"
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.network "private_network", ip: "192.168.33.10"
end

If I use

Code: Select all

  config.vm.network "private_network", type: "dhcp"

The vm gets an ip 172.28.128.3 and the host has a new vboxnet1 interface (ip 172.28.128.1), but the behavior is the same as the static configuration.

Sorry but we don't support vagrant. They change too many things and use special scripts that are unknown to us making it too time consuming to diagnose.
