Subject Re: Blue screen appear if using the template uploaded
Date Tue, 05 Feb 2013 17:03:50 GMT
Hi Fabrice,

I'm not aware of any such feature, but there have been other
situations where people have needed ways to customize the virtual
hardware or VMX file gat CloudStack creates, so it might be an
improvement worth exploring.

In your case, I'm curious why you would need/prefer LSI Logic SAS over
LSI Logic Parallel. I've found the performance to be roughly identical
and I've found it easier to do guest-level automation with the LSI
Parallel controller (due to how disks are detected).
