Hi
Just alter the device from hda to hdb
eg
from
disk = ['file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/system.img,hda,w',
'file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/oracle10g_x86.img,hda,w',
',hdc:cdrom,r'......
to
disk = ['file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/system.img,hda,w',
'file:/OVS/running_pool/OVM_EL4U5_X86_HVM_10GB/oracle10g_x86.img,hba,w',
',hdc:cdrom,r' .......
this way you mount you system image root volume as a device [hda]
and your oracle10g image as a device [hdb]
