[Xen-users] LVM - DomU drives not found

[tt tt <tt_745@xxxxxxxxxxx>]

Hi,

We are using Xen on Centos 5 using a LVM file system. Having successfully 
created a number of Windows domU's I am now trying to migrate over a few Linux 
machines. 

I have created a LVM structure for a domU as follows on the host OS:

/dev/vg0/machine1
/dev/vg0/machine1_boot

mkfs.ext3 /dev/VolGroup00/machine1
mkfs.ext3 /dev/VolGroup00/machine1_boot

In the config file /etc/xen/machine1 have created the disks as follows:

disk = [ 'phy:/dev/VolGroup00/machine1,hda1,w',  
'phy:/dev/VolGroup00/machine1_boot,hda2,w']

When mounting Centos 4 or 5 from an iso it cannot find any drives. Looking in 
/proc/ide using a rescue disk only shows the cd drive and not the file systems. 
 

If I just create a disk "hda" it appears in the domU fine and I can create all 
the sub partitions. Looking through the previous messages on this list the 
above does appear to be possible but I am unsure how to resolve this. 

Any suggestions?

Dave
