I can migrate the volume(in-use) from one host to another. The nova libvirt will call the 'rebase' to finish it. But if using ceph backend, it raises exception 'Swap only supports host devices'. So now it does not support to migrate volume(in-use). Does anyone do this work now? Or Is there any way to let me migrate volume(in-use) with ceph backend?</div><div style="font-family: 微软雅黑, Verdana, 'Microsoft Yahei', SimSun, sans-serif; line-height: 22.4px;"><br></div><div style="font-family: 微软雅黑, Verdana, 'Microsoft Yahei', SimSun, sans-serif; line-height: 22.4px;">Cheers,</div><div style="font-family: 微软雅黑, Verdana, 'Microsoft Yahei', SimSun, sans-serif; line-height: 22.4px;">Boxiang</div><span>
