Hi!
My xen-dom0 harddisk is terribly slow. I am running FC6 with Kernel 2.6.20-1.2948.fc6xen.
It is an HP dc5700 Machine with a Western Digital WD2500JS-60MHB5 Harddisk
I am not able to enable dma:
[root@m1 ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 10 MB in 3.32 seconds = 3.01 MB/sec
[root@m1 ~]# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
[root@m1 ~]#
This is my Hardware:
[root@m1 ~]# lspci

What can i do, to get dma enabled and have a little speed up?
Thanks!
