I've a network issue with a centos7 vagrant box.
When I setup a private network, with fixed IP, this one is well binding
first, but get lost after some seconds/minutes.

With this vagrant file :
Vagrant.configure(2) do |config|
config.vm.box = "centos7"
config.vm.hostname = "docker-registry"
config.vm.box_url =
"https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box";
#config.vm.network "public_network"
config.vm.network "private_network", ip: "192.168.100.20"
#config.vm.synced_folder ".", "/vagrant", type: "nfs"
# VirtualBox
config.vm.provider :virtualbox do |vb|
vb.name = "poc_docker"
vb.memory = 3072
vb.cpus = 2
vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
vb.customize ["modifyvm", :id, "--natdnsproxy1", "on"]
end
end
When I connect on the box, it seems that the ip is lost.
sudo /sbin/ifup eth1
Fix the problem temporary, but the IP get losts sometime again.
Rebooting the box (vagrant halt && vagrant up) seem to fix the problem
permanently.
I've try to create a custom centos 7 box with Packer
( https://atlas.hashicorp.com/sfeirbenelux/boxes/centos7), and I reproduce
the issue too.
I suppose that's a Centos 7 specific issue ?
Do you already have the same problem ? Is there a way to fix this by adding
a vagrant command ?
My environment :
OS X Yosemite
➜ ~ vagrant --version
Vagrant 1.7.2
➜ ~ VBoxManage --version
4.3.26r98988
