Hi, I installed KVM on a CentOS 7.4 host. The guest is also installed in CentOS 7.4, the network works perfectly. Both Host and Guest machines have the same OS. I do not understand why I have an SSL error on the guest and not on the host while the two computers have the same OS installation. The firewalld, selinux, fail2ban services are not installed on host and guest. Is there an extra manipulation that I have forgotten to do? Many thanks. Below my log on Host and Guest.
