[Qemu-discuss] Add a Ceph disk using blockdev-add

[Matthew Anderson]

Hi All,

I'm trying to hot add a disk to a running QEMU 2.1.2 VM but haven't
had any joy getting the syntax right or figuring out if it's actually
supported. Does anyone know if this is possible using the blockdev-add
QMP command? I've tried different combinations of rbd, raw and file
for the driver field but usually just get a syntax error.

My command looks like -
{ "execute": "blockdev-add",
    "arguments": { {"options" : {
        "driver": "raw",
        "file": { "driver": "file", "filename": "rbd:nearline/test" },
        "id": "drive_test"
      }}
}

Thanks!
