[one-users] KVM Qemu does not mount DATABLOCK.

[Ruben S. Montero]

Hi,

This seems more a KVM/libvirt issue than an OpenNebula one as the
three devices are listed in the deployment file. There has been some
problems reported when mixing ide and virtio disks, that may be cause
of the problem. You may try to put the three disks under virtio to
check if that's the problem.

Cheers

Ruben
