[libvirt] iscsi target name including colon

[Libaiqing]

Hi,
   I am testing the soft iscsi.
   Using targetcli,I emulate an iscsi target from a file.

  o- iscsi ............................................................................................................ [Targets: 1]
  | o- iqn.2003-01.org.linux-iscsi.fedora121.x8664:sn.712a3704dac7 ....................................................... [TPGs: 1]
  |   o- tpg1 ............................................................................................................ [enabled]
  |     o- acls .......................................................................................................... [ACLs: 0]
  |     o- luns .......................................................................................................... [LUNs: 1]
  |     | o- lun0 ............................................................................ [fileio/r1 (/home/fedora18_wolv.img)]
  |     o- portals .................................................................................................... [Portals: 1]
  |       o- 186.100.8.121:3262 ............................................................................................... [OK]


   Then start a vm with the following config.
     <disk type='network' device='lun'>
        <driver name='qemu' type='raw'/>
        <source protocol='iscsi' name='iqn.2003-01.org.linux-iscsi.fedora121.x8664:sn.712a3704dac7'>
           <host name='186.100.8.121' port='3262'/>
        </source>
        <target dev='vda' bus='virtio'/>
     </disk>

Then qemu reports an error:
    process exited while connecting to monitor: qemu-kvm: -drive file=iscsi://186.100.8.121:3262/iqn.2003-01.org.linux-iscsi.fedora121.x8664%3Asn.712a3704dac7,if=none,id=drive-virtio-disk0,format=raw: Failed to parse URL : iscsi://186.100.8.121:3262/iqn.2003-01.org.linux-iscsi.fedora121.x8664%3Asn.712a3704dac7
qemu-kvm: -drive file=iscsi://186.100.8.121:3262/iqn.2003-01.org.linux-iscsi.fedora121.x8664%3Asn.712a3704dac7,if=none,id=drive-virtio-disk0,format=raw: could not open disk image iscsi://186.100.8.121:3262/iqn.2003-01.org.linux-iscsi.fedora121.x8664%3Asn.712a3704dac7: Invalid argument


The rootcause is the colon in iscsi target name iqn.2003-01.org.linux-iscsi.fedora121.x8664:sn.712a3704dac7  passed to qemu as %3A by libvirt.

Is this an issue? 

Could you give me some advise to debug this problem ? I can provide more information if need.
