How can I optimize SQL Server 2005 Running in Hyper-V?

First off, I'm a SQL noob. My company uses an application called CCH ProFx Document, which uses a SQL backend. When it was first installed, it was running in VMWare Virtual Server. Approx. a month ago I converted the VMDK to Windows Server 2008 Hyper-V and the problems started happening. CCH claims its because I converted to Hyper-V. They think SQL is overwhelming the I/O path of Hyper-V. What can I do to find and correct any I/O problems I have? It's SQL 2005 Standard running on Windows Server Standard 2003, 4 GB of allocated RAM. The host is a Dell 2900 Dual Xeon Quad 2.5 Ghz w/ 8GB RAM. 3 15k 146GB SAS drives.

SQL server in a VM is a bad idea in general.  The achilles heel of VM's is I/O, so I'm not surprised that you're having this issue.  That said, I know that in VMWare, you can map a physical drive to a virtual one so that you get the benefit of all the spindles.  Not sure about Hyper-V as I haven't messed with it.

Why the change to HyperV?

We're were in VM Server 1.6 that had memory limitations. Hyper-V gives us more flexibilty.

My stance has always been and will continue to be "no SQL Server on VM".  You might have better luck in the Server 2008 forum.

I've run SQL Server 2005 inside Hyper-V without any issues.
Optimizing a virtualized SQL box isn't much different than a physical, as it's all about I/O.  What I've done is setup three separate virtual disks for the SQL box - one for OS, one for trans logs, one for database.  Make sure all are connected via a SCSI controller and if possible, create each virtual disk on separate physical disks to leverage multiple bus speeds.
While not the best for a big, heavily utilized database server it works just fine for smaller, purpose-oriented dbs and development work.  If it ran fine under VMWare, it will run fine under Hyper-V.
Let me know if you get stuck making the specific changes.
