another server using libvirt/KVM ?
No, qemu-kvm implement user-space access to rados block devices via
librbd. So that will work fine even without the kernel module. Both

The ceph kernel module is only for mounting rbd block devices on bare metal
(technically you could do it in a vm but there is no good reason to do so).
