Re: [ovirt-devel] oVirt Cloud-init

I'm apparently really bad at email, I replied only to Shahar, not the whole thread. Vinzenz your email slipped first, so to answer your question: It's the latest Centos 7 with these installed: cloud-init-0.7.5-10.el7.centos.1 kernel-3.10.0-514 <tel:3.10.0-514>.el7 ovirt-guest-agent-common-1.0.13-1.20161220085008.git165fff1.el7.centos The setup script I use to create a template is here: https://github.com/myoung34/vagrant-ovirt4/blob/master/tools/prepare_redh... <https://github.com/myoung34/vagrant-ovirt4/blob/master/tools/prepare_redh...

The engine-host is oVirt Engine Version: 4.1.0.4-1.el7.centos The ruby SDK i'm working with is 4.1.2 Halfway through I realized that it's actually supported in the API: custom_script String dns_search String dns_servers String It also shows usage here: https://github.com/oVirt/ovirt-engine-sdk-ruby/blob/master/sdk/examples/s... <https://github.com/oVirt/ovirt-engine-sdk-ruby/blob/master/sdk/examples/s... Here's some verification: 66: vm_configuration[:initialization][:dns_servers] = iface_options[:dns_servers] unless iface_options[:dns_servers].nil? 67: vm_configuration[:initialization][:dns_search] = iface_options[:dns_search] unless iface_options[:dns_search].nil? 68: require 'pry' 69: binding.pry 70: => 71: machine.start( 72: use_cloud_init: true, 73: vm: vm_configuration 74: ) 75: 76: @app.call(env) [1] pry(#<VagrantPlugins::OVirtProvider::Action::StartVM>)> vm_configuration => {:initialization=> {:host_name=>"test", :nic_configurations=>[{:name=>"eth0", :on_boot=>true, :boot_protocol=>"static", :ip=>{:version=>"v4", :address=>"192.168.2.200", :gateway=>"192.168.2.1", :netmask=>"255.255.255.0"}}], :custom_script=>nil, :dns_servers=>"192.168.2.1", :dns_search=>"test.local"}} But it didn't do anything: [vagrant@test ~]$ cat /etc/resolv.conf # Generated by NetworkManager search localdomain [vagrant@test ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 NM_CONTROLLED=no NETMASK=255.255.255.0 BOOTPROTO=static DEVICE=eth0 IPADDR=192.168.2.200 GATEWAY=192.168.2.1 ONBOOT=yes The same is also true using cloud_init: ovirt.cloud_init =<<EOF write_files: - content: | wat path: /tmp/something.txt permissions: '0644' network-interfaces: | auto eth0 iface eth0 inet static address 192.168.2.201 network 192.168.2.0 netmask 255.255.255.0 gateway 192.168.2.1 dns-nameservers 192.168.2.113 192.168.2.1 EOF
