Hi Team,

I’ve encountered resize causing issues if source flavor has swap-disabled and target flavor have it enabled or vice-versa.
It results into duplicate vdb error. Following are the steps:-
        1       Create an image-backed(no volume attached) instance with flavor having swap disabled.
        2       Create a volume and attach it with the instance (e.g. get attached at /dev/vdb).
        3       Resize it to a bigger flavor which has swap & ephemeral enabled.
        4       It results into error complaining about duplicate vdb:-
                  libvirt.libvirtError: XML error: target 'vdb' duplicated for disk sources '/var/lib/nova/instances/1860acb4-012f-4528-b2ef-XXXXX/disk.swap'

Should one not do resize with swap & no-swap flavor combo? Please provide thoughts/suggestions for the same.

Thanks,
Gaurav
