Hello, I'm looking to use DRBD for the first time with my existing KVM servers to facilitate live migrations, and had a few questions. I've seen lots of documentation on using DRBD with LVM based virtual machine disks, but I prefer to use qcow2 images. Is it possible to have DRBD replicate the volume all the images are stored on rather than each individual VM LVM block device? What would be used to ensure that only one KVM node is accessing the disks at a time until migration is needed? If anyone has any advice or suggestions please let me know. This is my first time using anything for file system replication.<div>

Is it possible to use a cross-over cable between my two nodes to facilitate the DRBD function? Would I still be able to monitor and control DRBD via the node's public port using a different server?</div>
