[Users] New virtual disks will NOT reliably be placed where I specified

I have a new ovirt installation that I am playing with. If it matters, I built it by installing and patching Fedora 16, installing the ovirt-engine RPM and then configuring this same machine as my "node", or host, or whatever you call it. I created 3 NFS shares on this machine for the 3 required domains, and then created those domains in the ovirt-engine. I have uploaded a ISO and created a couple of VMs and they work. HOWEVER, when create a virtual disk for my VMs, I specifiy the "data domain" as its location, and have then found, twice in three tries, that the virtual disk is placed on the "export domain". I am quite sure I am specifying my "data domain" when I create the disk. But then when I click on the VM, and then open the "General" tab, the "Resides on Storage Domain" field says "export". And when I look at the host, the virtual disk really IS in the export domain: [root@oravm2 exportdomain]# find . -type f | xargs ls -l ... -rw-rw---- 1 vdsm kvm 10737418240 Mar 1 09:17 ./0efcc135-2a17-4cfd-ba7d-c3735349d455/images/fda97fda-f0ca-4926-9a3e-af836466b5b1/9167e3a9-1e98-4f11-a99c-616adbe52f95 I can't imagine what I might be doing wrong to make this happen. There is no domain placement when I create the VM, as best I can tell. Placement is given only when I create the virtual disk. Anyone have an idea on this?
