[one-users] Problem with DataBlock iamges

[Ruben S. Montero]

Hi,

There is a limitation on the number of IDE bus in KVM. Sometimes the
automatic disk placement in the IDE bus by OpenNebula hits this
limitation.

You can try to fix the targets for both disks.
...

DISK = [ IMAGE_ID = 72, TARGET=hdb ]

Also SCSI may help... But before trying that can you check the
deployment.0 file (generated in /data1/opennebula/var//704/)... What
targets are being used?


Cheers

Ruben
