[libvirt] iscsi target name including colon

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. Regards, baiqing
