Description

This is caused by a string change included as part of bug 1007388 where extra information has been appended to the end of 'iscsiadm -m session' output. The libvirt iSCSI backend has a strict regex that parse session information that is no longer matching. We either need to back this out of iscsi-initiator utils or change libvirt to ignore additional information added to the end of the output line. I have proposed an upstream patch loosening the regex: https://www.redhat.com/archives/libvir-list/2014-February/msg01279.html Fixed upstream by:
commit 57e17a74b76fd8f93012d6d0407106e9a2d5c5e3

Ignore additional fields in iscsiadm output
git describe: v1.2.1-290-g57e17a7
I can reproduce this bug with packages: libvirt-1.1.1-23.el7.x86_64 iscsi-initiator-utils-6.2.0.873-18.el7.x86_64 Steps: 1. define a iscsi pool and start it. 2. then update iscsi-initiator-utils-6.2.0.873-18.el7.x86_64 to iscsi-initiator-utils-6.2.0.873-19.el7.x86_64 3. # dmesg ...

Verified pass with libvirt-1.1.1-24.el7, steps as comment #8. This request was resolved in Red Hat Enterprise Linux 7.0.
