svn commit: r273102 - head/share/examples/bhyve

New Revision: 273102

Log:
  Use '-e' to check if the virtio backing file has already been created.
  
  The '-f' check works fine on a regular file but not if the backing file is
  a device (e.g., /dev/md0). In this case it would print a misleading but
  otherwise benign message about the backing file not being present.
