[Users] Passing a hint/message to a VM when it boots
Hello, when creating a new VM from a template, i'd like to pass a hint of some sort ( perhaps a hostname ) to it so that the internal config managment system can do the rest of the setup. This should also be programmable via the REST API, as I want to use it for automated deployments. Has anyone had success doing this with Ovirt? i can only see two approaches: - Put the hint in a floppy / iso and mount it on the VM. - Hardcode a MAC address and let a DHCP server provide the hostname Both of these do not seem very optimal to me. I'd appreciate some thoughts from the community on how to proceed. Thanks in advance, k

did you try the kernel boot options?

Hi, yes, using a kernel boot option would be nice, and there is an option for it in Ovirt, but I am not getting it to work. When i want to specify a boot parameter, I also have to specify a kernel path. When i specify the internal kernel, the VM fails to boot. Is this supposed to be an "external" kernel ( like paravirtualized Xen? ) On 03/16/2012 11:11 PM, Itamar Heim wrote:

any kernel should work. question is if the path you are using has permissions for vdsm to use (check the log)
