John, Here is the readme for the localdisk hook: https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/localdisk/README In order to use it you need to install it on the host, configure the VM User Property on the engine, and set the property on the VM that will use the hook. Note that a lot of operations are not supported when this hook is in use. Please tell if the readme is missing some information.

Hi,

I've be googling and also trawling the oVirt documentation trying to find instructions on how to install and use VDSM hooks in general but specifically the "vdsm-hook-localdisk" hook. I have a machine that has a large amount of free space on SSD which I was hoping to use to store a pinned VM which requires fast I/O throughput and doesn't require HA. In essence, I'm trying to figure out how to use a hypervisor host as both a member of my cluster but also to provision a VM using local storage. If anybody could point me in the right direction I would be very grateful.

Thanks

Hi John, the method you specified should work.

Have you checked the documentation here? http://www.ovirt.org/develop/developer-guide/vdsm/hooks/
