If possible I'd like to get some opinions on the following bug report:


Obviously, I believe that virt-manager should be defaulting to disabling 
caching for disks backed by raw volumes as qemu suggests.  There is a 
huge performance difference in doing so.  AFAIK, there is no difference, 
in terms of risk, between no cache and Writethrough.

I don't quite get Daniel's response and subsequent closing the bug 
report indicating that it's a policy decision for virt-manager and the 
like.  I filed the report where virt-manager's web site indicated the 
report should be filed.
