Hi,
On the MN no selinux no firewall and for now I am using one Compute node so
practically no traffic and if you see the http access_log the first file is
being downloaded the problem appears with the second file.
I tried with wget from another machine and it works so files on the http
server are reachable.
The compute vm node is configured to boot from it's network card i.e. pxe
boot
The vm is booted manually by me from virt-manager or virsh
The configuration of the vm is :
2 vcpu 2Go of ram 20Go hdd virtio
Two vnic virtio, RNG device and the rest of the default hardware added by
virt-manager when creating a vm.
Regards.
