For the vagrant version of devcloud that I am working on (which may become devcloud 3?), I have had to switch the network cards in Virtualbox.
Devcloud2 has eth0 - host only network eth1 - nat network However, Vagrant requires the first network card to be the NAT one, i.e. eth0 - nat network eth1 - host only network Question 1: Am I correct in thinking that I just need to make the following changes to the devcloud2 network setup: auto xenbr0 iface xenbr0 inet static bridge_ports eth0 # <-- devcloud3 changes this to eth1 address 192.168.56.10 netmask 255.255.255.0 network 192.168.56.0 broadcast 192.168.56.255 gateway 192.168.56.1 dns_nameservers 8.8.8.8 8.8.4.4 post-up route del default gw 192.168.56.1; route add default gw 192.168.56.1 metric 100; auto xenbr1 iface xenbr1 inet dhcp bridge_ports eth1 # <-- devcloud3 changes this to eth0 dns_nameservers 8.8.8.8 8.8.4.4 post-up route add default gw 10.0.3.2 # <-- devcloud3 changes this to 10.0.2.2 Question 2: What is the purpose of xenbr0 and xenbr1? I.e. how are there bridges used by cloudstack / xen? Many thanks, Chris
