thanks much for the answer and the interest. I followed the guidelines at http://github.com/cmusatyalab/elijah-openstack with a regular All-In-One Single Machine devtsack installation.
Regarding the resource lack issue...for now there is not an immediate solution, but i hope i can update my RAM to 8 GB soon.
Anyway, I give you more information about my test environment:
Ubuntu Trusty Desktop:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Devstack Version: solinux@solinux-PC:~/devstack$ git branch -a
remotes/origin/HEAD -> origin/master
Libvirt version: libvirtd --version
libvirtd (libvirt) 1.2.2
python-libvirt = 1.2.2-0ubuntu2.
Kvm version: kvm --version
QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.21), Copyright (c) 2003-2008 Fabrice Bellard
I have the other packages relative to libvirt at version:
libvirt0 = 1.2.2-0ubuntu13.1.16.
libvirt-bin = 1.2.2-0ubuntu13.1.16.
When i try to enforce your same version with sudo apt-get install libvirt-bin=1.2.2-0ubuntu13.1.14; sudo apt-get install libvirt0=1.2.2-0ubuntu13.1.14, I receive the error message:
E: Version '1.2.2-0ubuntu13.1.14' for 'libvirt-bin' was not found.
Do I have to install them manually?
Now i'll try again with a new clean './stack.sh' to have new log file in /opt/stack/logs, perhaps this will give me more informations to analyze.
