I want to install Vagrant to run parallel systems. Vagrant uses VirtualBox to spin multiple VMs. While doing so I have two observation which is blocking me to proceed further. # Issues: '''1. The Acquired ip through DHCP (NAT) is ""10.0.2.15"". All the new VM under NAT, acquire the same ip (""10.0.2.15"") 2. The Guest VM is not ping able from my Host Machine.''' NOTE: I am using Ubuntu-Server 14.04 for my guest VM setup. # Approach: # 1 : [FAILED ..] Manually tried creating a VM (instead Vagrant ) I have also tried with all the provided virtual adaptor with NAT mode, unfortunately there is no difference. PCNet PCI II (Am79C970A); PCNet FAST III (Am79C973, the default); Intel PRO/1000 MT Desktop (82540EM); [Default one] Intel PRO/1000 T Server (82543GC); Intel PRO/1000 MT Server (82545EM); Paravirtualized network adapter (virtio-net). # 2 : [Working] Tried downloading a Box from Vagrant and tried to run, it works perfect. # 3 : [Working] I have created a the same VM under bridge networking, it is working by acquire the ip from my physical network. and accessible from my Host machine. # User Story: I want to create a Base Vagrant VM with custom configuration for my CI setup. # Reference: My Host Network configuration: {{{ Soumyas-MacBook-Pro:RawMachine1 soumya$ ifconfig lo0: flags=8049 mtu 16384 options=3 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 nd6 options=1 gif0: flags=8010 mtu 1280 stf0: flags=0<> mtu 1280 en0: flags=8863 mtu 1500 ether 6c:40:08:9e:d0:5a inet6 fe80::6e40:8ff:fe9e:d05a%en0 prefixlen 64 scopeid 0x4 inet 192.168.1.7 netmask 0xffffff00 broadcast 192.168.1.255 nd6 options=1 media: autoselect status: active en1: flags=8963 mtu 1500 options=60 ether 72:00:06:43:af:80 media: autoselect status: inactive en2: flags=8963 mtu 1500 options=60 ether 72:00:06:43:af:81 media: autoselect status: inactive bridge0: flags=8863 mtu 1500 options=63 ether 6e:40:08:e9:57:00 Configuration: id 0:0:0:0:0:0 priority 0 hellotime 0 fwddelay 0 maxage 0 holdcnt 0 proto stp maxaddr 100 timeout 1200 root id 0:0:0:0:0:0 priority 0 ifcost 0 port 0 ipfilter disabled flags 0x2 member: en1 flags=3 ifmaxaddr 0 port 5 priority 0 path cost 0 member: en2 flags=3 ifmaxaddr 0 port 6 priority 0 path cost 0 nd6 options=1 media: status: inactive p2p0: flags=8843 mtu 2304 ether 0e:40:08:9e:d0:5a media: autoselect status: inactive awdl0: flags=8943 mtu 1452 ether 8e:5f:a4:16:d5:3b inet6 fe80::8c5f:a4ff:fe16:d53b%awdl0 prefixlen 64 scopeid 0x9 nd6 options=1 media: autoselect status: active vboxnet0: flags=8842 mtu 1500 ether 0a:00:27:00:00:00 Soumyas-MacBook-Pro:RawMachine1 soumya$ ping 10.0.2.15 PING 10.0.2.15 (10.0.2.15): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3 Request timeout for icmp_seq 4 Request timeout for icmp_seq 5 ^C --- 10.0.2.15 ping statistics --- 7 packets transmitted, 0 packets received, 100.0% packet loss Soumyas-MacBook-Pro:RawMachine1 soumya$ }}} I have also attached the screenshot of VirtualBox Guest VM, Please have a look.
