Re: [Libguestfs] [PATCH v2] p2v: Allow virt-v2v input and output drivers containing '-' (RHBZ#1590220).

The new ‘-o rhv-upload’ output mode contains a '-' character in the name, but the regular expression which matched the output of the virt-v2v command did not recognize '-' as a valid character. It ended up mapping this to just "rhv" meaning two "rhv" entries would appear in the list of output drivers. Thanks: Ming Xie. ---
