I'm getting relatively slow disk performance on the host, which I guess I could live with, but I'm getting really slow disk performance on a Windows 2003 VM that I p2v'd. I've tried both IDE and virtio for storage, and each is giving less than 5MB/sec as measured by iometer.
Here is the output of pveperf on the host.
Here is info from the Dell Openmanage utility I installed on the host. I wanted to keep things vanilla and not install anything on the host, but Openmanage+DRAC can be a real life saver on Dell servers.
pve-manager/2.1/f9b0f63a is the output of pveversion
I have four 15k SAS drives in raid 10. I don't remember the exact number, but I'm pretty sure that I was getting over 100MB/s on Windows bare metal measured by iometer. It has 256mb battery backed cache, and if memory serves me right the raid options all look good.
Is there anything that you guys think I'm missing, or have any advice? Thanks in advance.
