Super slow VM disk IO

I've played with a few VMs created from scratch without (much) issue, but in testing migrating a physical box to a VM I'm running into super slow disk IO (like 100-200 KB/s max).

 

I'm wondering if because the .img file was created outside of my no-COW "domains" folder, maybe it "carried in" the C attribute when I moved it under "domains"?  I tried lsattr on the file but end up getting an "lsattr: Inappropriate ioctl for device while reading flags" error.

 

Does anybody have any suggestions on how to check Copy On Write attribute for a file in Unraid or know if it is removed when a file is moved (or copied) into a no-COW folder?
