Hi Juan, Okay sure.. The following xml i used <action> <vm> <os> <boot dev='cdrom'/> </os> <initialization> <cloud_init> <host> <address>test2</address> </host> <users> <user> <user_name>root</user_name> <password>test</password> </user> </users> <network_configuration> <nics> <nic> <interface>virtio</interface> <name>eth0</name> <boot_protocol>none</boot_protocol> <on_boot>true</on_boot> </nic> </nics> <dns> <servers> <host> <address>x.x.x.x</address> </host> </servers> </dns> </network_configuration> </cloud_init> <custom_script> #cloud-config phone_home: url: http://x.x.com/api/xx/api_receive.php </custom_script> </initialization> </vm> </action> -- Regards Shanil On Thu, Sep 11, 2014 at 1:48 PM, Juan Hernandez <jhernand@redhat.com> wrote:

Hi Juan,
It seems the it doesn't contains the "phone_home " section in the cat /mnt/openstack/latest/user_data
the following is the output
#cloud-config ssh_pwauth: true disable_root: 0 output: all: '>> /var/log/cloud-init-output.log' user: root password: admin123 chpasswd: expire: false runcmd: - 'sed -i ''/^datasource_list: /d'' /etc/cloud/cloud.cfg; echo ''datasource_list: ["NoCloud", "ConfigDrive"]'' >> /etc/cloud/cloud.cfg'
but if i try with the
<files> <file> <name>ignored</name> <content><![CDATA[runcmd: - echo 'Test script !' > /iwashere_test.txt ]]></content> <type>plaintext</type> </file> </files>
then it will create the /iwashere_test.txt and write the contents and in that time the cat /mnt/openstack/latest/user_data is
cat /mnt/openstack/latest/user_data #cloud-config ssh_pwauth: true disable_root: 0 output: all: '>> /var/log/cloud-init-output.log' user: root password: admin123 chpasswd: expire: false runcmd: - 'sed -i ''/^datasource_list: /d'' /etc/cloud/cloud.cfg; echo ''datasource_list: ["NoCloud", "ConfigDrive"]'' >> /etc/cloud/cloud.cfg' runcmd: - echo 'Test script !' > /iwashere_test.txt
so, i think the custom script section is not working, i am attaching the vm log as a screenshot.
Can you share the XML document that you sent to the RESTAPI in order to populate the "phone_home" section?

I think it should work, but it depends completely on cloud-init itself. I'd suggest you check the content of the generated cloud-init configuration file (as described in a previous mail). If it contains the "phone_home" section then you can discard a problem with oVirt, and focus on clud-init.
