Infrastructure Software

Greetings,

I've first tried to create a HVM virtual machine in OVS/OVM 3.2.1 manualy using xm create.
Very slow (could be VNC connection). Raised DOM0 host memory from 832m to 1024m.
Told the 1 guest to use at least 14G and max 15G.
After running the domU a few hours (too slow to work with) it crashes with momory issues.

So now I've started using Oracle VM Manager to create the virtual machine.
Used fdisk to create Linux VM partitions.
Rebooted the server completely to be sure the new partition table is used.

[root@OVS2-EUN ~]# fdisk /dev/sda -l

When I try to create a Pgysical volume using
pvcreate /dev/sda5 /dev/sda6 /dev/sda7
the answere is:
Device /dev/sda5 not found (or ignored by filtering).
Device /dev/sda6 not found (or ignored by filtering).
Device /dev/sda7 not found (or ignored by filtering).

Oracel VM Manager doesn't see any physical disk before or after creating the partitions.

Which step am I missing? Where can I find this filtering?
Any other checks I can do?

Strange thing is: I am able to mkfs ext3 to /dev/sda5 and mount it.
OVM Manager does show storage initiators.

Kind regards,
D.
