Bad disk IO performance for window vm

646666May 18 2011 — edited Jun 2 2011
Hi,
I created some windows vm on OVM and find the disk IO performance is really bad.

For example:
I created a win2008 R2 64bit VM with DB, and installed OVM windows PV Drivers on it.
And I assign the CPU as 2.4G * 6, memory as 8G, HD as 100G.
If I create a 2G tablespace for DB, it will spent over 1 hour.
The installation for Oracle DB will spend 2 days.

I think it's caused by OVM server's HD.
It's 500G 2.5inch hard disk *4, and I did raid0+1 for it.
The OVS folder is 1T.

What should I do to improve the IO performance.

Thanks!
