Hi Christophe,
it's clear now that the FE and demo VMs don't start properly for some reason. Please check that your head-node is capable of running KVM virtual machines at all by executing
$ lsmod | grep kvm_
If this doesn't show either kvm_intel or kvm_amd, virtualization support has been disabled in the BIOS of your head and you need to re-enable it.
If kvm_amd/intel is loaded you can try to startup the FE node VM directly with the Qlustar KVM management script on the cmdline as root:
$ manage-kvm-guest -a start -n login
This should then tell you where things go wrong.
BTW: Renaming head and FE to jcluster(t) while executing the installer is supported and cannot cause the problem.
Best,
Roland

Thanks for the very fast answer Roland.
I did learn tmux on my linux workstation, beside the fact that its really cool and plan to use it the future, I am still struggling to have the demo and fe working in tmux
When starting the demo-system (*demo-system -a start)* -> console-demo-vms, I know as a fact now that I am in tmux but I am still on the c1-head. any Ctrlr-t n (or p) said "no next windows" , not only I can't switch to demo but also fe which if I understand correctly must have started automatically.
Once I exit from tmux with Ctrl-t d,
tmux ls gives: tmux ls error connecting to /tmp/tmux-0/default (No such file or directory)
I don't see demo or fe.
When trying to start console-fe-vm console-fe-vm No tmux session 'login-vm' with server socket 'ql-vms'
What's happening here ? note that during the install I rename the host c1-head jcluster and the fe jclustert (jcluster and jclustert are found in the DNS). Would it change anything ?
*I I do
0 root@jcluster ~ # dsh -a uptime beo-201: ssh: connect to host beo-201 port 22: No route to host beo-202: ssh: connect to host beo-202 port 22: No route to host beo-203: ssh: connect to host beo-203 port 22: No route to host beo-204: ssh: connect to host beo-204 port 22: No route to host login-c: ssh: connect to host login-c port 22: No route to host
So yes , no demo or fe connection. Why do you thing is happening.
Thanks for your help
