Can this provider be used to create a VM with iSCSI disk?

[NubemInvidia]

I can create VMs just fine when using local LVMs on the node. But I can't seem to use iSCSI targets from my SAN as the disks for the VMs. It fails to provision the disk, stating that it can't size the disk. Seems to me that even if I omit the disk size, it defaults to 8, but since it's an iSCSI target you can't specify the space the VM should use on that target so it errors out.

@NubemInvidia could you post an error you're getting?

Possibly related to #1599
