[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

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.

Libvirt (or rather libxml2 which is used for URI formatting) escapes special characters, but libiscsi doesn't decode them. This seems to be fixed in libiscsi git, but it hasn't been released yet: https://github.com/sahlberg/libiscsi/commit/e061cba1 Jan
Hi jan, Thankyou for your reply. I will try to hack libiscsi. Regards, baiqing
