ssh into kvm-clients

[brizly vaan van Ulciputz]

Hello Everyone,

ich wonder why i am not able to ssh-in in this case:

i have an kvm-'server' running 4 'guests'.

the guests are behind nat (default in kvm?).

running fresh fedora on all machine (host and guest), installed from
live-cd, enabled sshd and made sure system-config-firewall allows
ssh-in, i am not able to reach the guests by ssh.

i can ping them, by there from kvm-server given ip, by
openvpn-client-ip, all good.
[brizly at s28 ~]$ ping 192.168.24.22
PING 192.168.24.22 (192.168.24.22) 56(84) bytes of data.

but ssh - i just got:
[brizly at s28 ~]$ ssh 192.168.24.22
ssh: connect to host 192.168.24.22 port 22: No route to host


i don't know were to start searching, firewall, selinux, openvpn...

Other openvpn-clients - installed the same way, but 'real' machines, not
kvm-clients - are reachable. although from kvm-client to outside-host.

Any ideas?
