I am trying to add a 20 GB plain volume created through Horizon GUI to an
existing Windows 2012 R  VM running with VirtIO drivers installed. But this
volume adding results in the error as shown above,

trace tells to fix it by    rbd feature disable   ..   what is the
permanent fix for this issue ? and why it happens ?
