Thanks Roland,

Yes kvm works way better with virualization support ! ;-) I really thought I did turn it on while inspecting the bios prior to install !!!

Any way moving forward to new installation problem in spack :

first , I completely missed the softadm password ( I got the one for demo) . I was giving all the same password each time I got a request to give one . I guess this one was generated like the demo account but I completely missed it.   Not a big deal , try to change it under root in fe  but was not allowed. Use QluMan/ldap for that. was able to ssh softadm@jclustert (my fe hostname) to initialize the stack.

OK, very good it worked out so far.

Here is the  error message when trying to initialize the stack using the "spack install gcc@13.1.0 target=x86_64" command .....
