I ran into the problem of installing Windows on a large disk volume.
- OpenNebula 5
- Ceph as RBD
- Create DATABLOCK in RAW, virtio, 7Tb.
- Create template with DATABLOCK, CD of Win2012 & ISO with VIrtio drivers pack.
- Create VM and start installation process of Windows.
- At the step when we choose disk, change disk type to GPT format with DISKPART util.
All ok, but can`t create partition with 7Tb.
When I try to extend partition - get an error.
In disk management we see, that disk is MBR.
Is it problem in Virtio drivers or in something else?
