[libvirt-users] How can I rebase network disk?

Hi. I am using openstack, ceph and libvirt now. The live volume migration will call the libvirt rebase function in openstack nova project. https://github.com/openstack/nova/blob/stable/rocky/nova/virt/libvirt/dri... https://github.com/openstack/nova/blob/stable/rocky/nova/virt/libvirt/gue... But I use the ceph as the openstack block backend. And the type of disk is network in xml. <disk type='network' device='disk'> <driver name='qemu' type='raw' cache='writeback' discard='unmap'/> <auth username='cinder'> <secret type='ceph' uuid='86d3922a-b471-4dc1-bb89-b46ab7024e81'/> </auth> <source protocol='rbd' name='volumes002/volume-127f46fc-ef10-4462-af30-c3893cda31f9'> <host name='172.16.140.63' port='6789'/> </source> <target dev='vdb' bus='virtio'/> <serial>127f46fc-ef10-4462-af30-c3893cda31f9</serial> <alias name='virtio-disk1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> Now I found it is not supported to rebase network disk. It is only rebase block or file disk now. https://libvirt.org/html/libvirt-libvirt-domain.html#virDomainBlockRebase My question is that can I rebase network disk by some other ways from libvirt?
