Description Carlos Mestre González 2015-11-13 15:20:04 UTC 
Description of problem:
Starting a vm fails with a spapr vscsi disk as boot device. Seems having other disks with that interface attached works.

Version-Release number of selected component (if applicable):
vdsm-4.17.10.1-0.el7ev.noarch
vdsm-jsonrpc-4.17.10.1-0.el7ev.noarch
libvirt-client-1.2.17-13.el7.ppc64le
qemu-img-rhev-2.3.0-31.el7_2.1.ppc64le
qemu-kvm-rhev-2.3.0-31.el7_2.1.ppc64le
rhevm-3.6.0.3-0.1.el6.noarch

How reproducible:
100%

Steps to Reproduce:
1. Create a vm (with default values, Desktop, Custom OS, no nic)
2. Add a disk with spapr-vscsi interface (My tests were 10GB/ with either iscsi/nfs, sparse or not) - disk starts fine.
3. Start the vm

Actual results:
or] (ForkJoinPool-1-worker-1) [72c52cf1] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM test_vm_4 is down with error. Exit message: XML error: target 'sda' duplicated for disk sources '/rhev/data-center/a723a57a-e118-466e-9b8b-63cf66814f17/1bab0f28-536e-446b-80d3-4c4c0e07789e/images/2f06078a-7d90-4414-a2c5-db20395fe194/4450f84d-49e6-4d09-8f0b-06af212295cb' and '<null>'.


Expected results:
vm starts properly

Additional info:
This also happens if you create a boot device with a different interface and then edit the interface to spapr-vscsi.
There doesn't seems to be an issue
Comment 1 Carlos Mestre González 2015-11-13 15:21:40 UTC 
Adding to storage since I think the XML issue falls into that component. Severity high.

engine.log

Pretty straight forward. creation of test_vm_4 and fails after start (search for duplicated)
Comment 3 Allon Mureinik 2015-11-15 08:56:14 UTC 
Tal, this is high priority due to the PPC focus.
Let's get someone to take a look at this please?
Comment 4 Amit Aviram 2015-11-15 09:54:09 UTC 
Carlos, can you please attach the VDSM logs also? (all files in "/var/log/vdsm/" in the host which tried to activate the VM)

A new run with same scenario.
