Hi,

Below the initial tests that I have executed with vdsm version
(4.13.0-11 and 4.13.0-12) on Fedora 20. Faced an 'iscsiadm: Error
while adding record: no available memory' trying to connect to iscsi
storage and opened a bugzilla [1] for it.

Thanks, Douglas!


Engine and otopi
=====================
oVirt Engine Version: 3.4.0-0.2.master.20131129131413.git3f58634.fc19
otopi-1.1.2-1.fc19

Testing this part of the project with f20 makes sense, too (but is less
likely to break).



Hosts
===============

# cat /etc/fedora-release
Fedora release 20 (Heisenbug)

# getenforce
Enforcing


vdsm 4.13.0-11 (current stable)
====================================

- Host deployed

NFS:
- Added NFS DATA and ISO [OK]

have you tried to populate using iso-uploader / image-uploader?
is log-collector able to collect logs for the traceback you've reported down 
here?

For the record on mailing list:

Initially, I have used manual steps. As we talked over IRC, I could do a test for now against ovirt-log-collector and created below bz.

F20 - ovirt-log-collector: conflicts with file from package sos-3.0-3.fc20.noarch

To move ahead with block storage testing, could you try to rebuild
iscsiadm or run Vdsm with fibre channel?


I have found that iscsi-initiator-utils-6.2.0.873-11.fc20.x86_64 (or higher) introduces this error.

I was able to create and run a virtual machine with the last build before the above one (iscsi-initiator-utils-6.2.0.873-9.fc20.x86_64).

Also did manual tests with below versions and it worked as well:
iscsi-initiator-utils-6.2.0.873-5.fc20.x86_64
iscsi-initiator-utils-6.2.0.873-7.fc20.x86_64
iscsi-initiator-utils-6.2.0.873-9.fc20.x86_64

Finally, I have talked with iscsi-initiator-utils package maintainer and he is aware of the problem.
