I may be confusing myself here so I'm asking for some clarification.
I have a large XenServer install that is currently using lvmoiscsi. I am looking for ways to reduce actual disk space usage. I am running ONLY linux VM's in this environment.
The sparse provisioning and chaining that the VHD format supports seems like the ticket but it seems to only support Windows bases VM's using NFS SR's or the the supported StorageLink SR's.
So, can I have linux VM's using sparse provisioning and chaining? Everything I keep reading and what I understand says no. I'm willing to re-work my storage setup if necessary. I currently am using Nexenta filer to serve up my iSCSI LUN's but it can serve most anything out there.
Someone please help me clear this up!!!
