Any chance this will change? It is a severe limitation to not be able to use local storage available to a host as that is often very fast storage.
This will couple the vm to this host, so you cannot run it to another host. If this host is down, you cannot run the vm on any other host, since your storage is gone.
Don't you think this is a severe limitation as well?
There are many things that tie a VM to a host, like USB device passthrough, but that's not reason to remove all such support from oVirt, is it? In my case, I'd like to mix iSCSI and local storage, because I have a couple of systems that need higher disk I/O that I'd like to put on my shared storage. The two systems are redundant to each other, so that is taken care of at a different layer. The two systems don't however consume all the resources of the host machines (lots of CPU and RAM available). I'd like to make them nodes in my oVirt cluster, so those resources can be used for other VMs (that are on shared storage for that level of HA), but I can't do that (at least as far as I know, with oVirt 3.5). I thought that had been mentioned as a feature for 3.6, but I don't see it anywhere in the features or release notes, so I assume that functionality is still not available. -- Chris Adams <cma@cmadams.net>
