Re: [libvirt] [PATCH] virsh: Parse "--mode readonly, shareable" in virsh attach-disk.

We can not attach a disk with mode of both readonly and shareable.

Before: # virsh attach-disk --domain jeos --source attach.img --target vdb --persistent --mode readonly --mode shareable error: option --mode already seen # virsh attach-disk --domain jeos --source attach.img --target vdb --persistent --mode readonly --shareable error: option --mode already seen # virsh attach-disk --domain jeos --source attach.img --target vdb --persistent --mode readonly,shareable error: No support for readonly,shareable in command 'attach-disk' After: # virsh attach-disk --domain jeos --source attach.img --target vdb --persistent --mode readonly,shareable Disk attached successfully
