Re: [ovirt-users] Passing custom script to cloud init using api

As the formatting of the XML is very important I'd suggest that you take the attached script (instead of copy & paste from the mail), change the password and VM id and run it. There are two kind of things that can go wrong here. One is that the engine/VDSM combination may not be generating the right file. To verify this start the VM with the attached script, and once it is started go to the hypervisor where it is running and find the corresponding qemu process: # ps -ef | grep -- '-name myvm' This will give you a very long command line. That command line should include a "-drive" option containing the full path of the disk image generated by the engine/VDSM, something like this: -drive file=/var/run/vdsm/payload/b5f087d4-022d-4d5f-8a1e-268c562c7bb1.b6fcddff571bb8c2028c61b623d172a6.img To inspect its content make a copy (just in case) and mount it: # cp -drive file=/var/run/vdsm/payload/b5f087d4-022d-4d5f-8a1e-268c562c7bb1.b6fcddff571bb8c2028c61b623d172a6.img /root/my.img # mount -o loop,ro /root/my.img /mnt Inspect the content: # find /mnt /mnt/openstack /mnt/openstack/content /mnt/openstack/content/0000 /mnt/openstack/latest /mnt/openstack/latest/meta_data.json /mnt/openstack/latest/user_data The content of the custom-script should be at the end of the "user_data" file, so take a look at that: # 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: mypassword chpasswd: expire: false runcmd: - 'sed -i ''/^datasource_list: /d'' /etc/cloud/cloud.cfg; echo ''datasource_list: ["NoCloud", "ConfigDrive"]'' >> /etc/cloud/cloud.cfg' runcmd: - echo "I was here!" > /iwashere.txt If your custom script isn't there then there is some problem in the engine/VDSM side, otherwise the problem is probably in cloud-init itself, and we will need someone with more knowledge of cloud-init to debug it. Don't forget to umount the file when finished: # umount /mnt -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg.
