Should be fixed in fusor-undercloud-installer: . 

Now using 'free -m' instead of 'dmidecode -t 17'. dmidecode provides very different output on different hardware configurations.

Similar fix was implemented in fusor-installer as well:

Looks like changes were merged on Friday.

Included in the 8/6 QCIOOO compose.

Comment 4 bmorriso 2016-08-19 19:40:32 UTC
Verified with QCIOOO-8.0-RHEL-7-20160815.t.3 on VM installation of undercloud ISO.

Available memory is correctly reported by launch-fusor-undercloud-installer.
