Ah, that's was my confusion then, because kvm_nodedata has nothing for
z10071 node, unless I only specify one disk, e.g. I get the rootvg image in
vmstorage, system will power on with rpower, but when I add in second disk,
I clear the cahced profile in kvm_nodedata ( chtab -d node=z10071
kvm_nodedata before power on) or it won't assign the second image as second
disk, but if I clear the cache I get the IDE error and nothing gets added
to the table. So I have nothing to compare a manual creation on the
hypervisor to...

I did get your point. But I have not your exactly images to create the
problem and fix it. Since you already verified the configure in libvirt
manually, if you can share me what the xml looks like and the different
between it with the one created by xCAT, it will be helpful for me to fix
it.
Thanks
Best Regards

I'm wondering if we have a communications problem on this thread...
I know how to make the image files work within libvirtd and I can
create/modify using cli tools and/or gui within libvirtd. The actual
actual of havign a second disk is not the problem. What is my issue is
having xCAT create teh profile when we rpower on the VM from MN and have it
do it ephemerally instead of xCAT managing an existing profile on a
hypervisor. In other words, w/o xCAT and it's dynamic VM profiles, this
works fine, it's only when I use xCAT that it ahs a problem, and I'm pretty
sure it comes down to the entry for vmstorage field, what I'm looking for
is if there is an accepted syntax for that field.
To restate, this is not a libvirtd issue, it's not KVM, it's getting xCAT's
dynamic xml creation to function with two image files that are not viritio.
If not possible, ok, then I'll go form there, but if it is possible, I jsut
need assistance with getting the syntax right on the xCAT definition of VM.

libvirtd is happy enough to run the second and/or third disk if I manually
insert via virt-manager or cli and VM sees the disk fine, so this issue is
how to get xcat to start an ephmeral VM that doesn't have a a porfile saved
on a hypervisor?
I can do this with lvm using vmstorage=phy:/path/tol/v1|phy:/path/to/lv2
on a node yealds to compalints from xcat, all I'm looking for is the
equivalent for a file based disk image

SLES 11 MN and VM xCAT-2.9.1 x86_64 KVM
I am in the process of converting from a LVM backed storage solution for
VMs to a raw file for disk housed in a GPFS cell. The design has the
hypervisors seeing gpfs as local storage, and when I add a single raw image
file and start the VM with it, everythign works fine. The problem is,
several of these VMs have two or three logical volumes presented as disks,
sd[abc]. When I attempt to convert the second lv to a file, the conversion
works fine, but I'm missing the proper syntax to add it to the vmstorage
object:
vmstorage=/gpfs/root/z10071_rootvg.img|r/gpfs/app/z10071_appvg.img
When attempting to power up, I receive this message:
z10000:~ # rpower z10071 on
z10071: Error: internal error Only 1 ide controller is supported
If I try to set the vmstoragemodel to scsi, xCAT will boot the VM but the
VM cannot find it's root disk. If I revert to a single disk and remove
vmstoragemodel I can successfully power on and boot into OS. So how to I
add more than one image file as a disk?
(Yes, I know, should be using virtio disks, these are legacy machines,
newer VMs will hopefully be using it)
