For this recipe, we are going to need the following:
- Two servers with libvirt and qemu installed and configured, named kvm1 and kvm2. The two hosts must be able to connect to each other using SSH keys and short hostname.
- A server with an available block device that will be exported as an iSCSI target and reachable from both libvirt servers. If a block device is not available, please refer to the There's more... section in this recipe for instructions on how to create one using a regular file. The name of the iSCSI target server in this recipe is iscsi_target.
- Connectivity to a Linux repository to install the guest OS.
