Hi bluelupo,
iptabeles ist installiert.
Habe in einer Ubuntu Documentation
https://help.ubuntu.com/community/KVM/Networkingfolgendes gefunden:
Troubleshooting
No Default (Usermode) Connectivity
If you are using default (usermode) networking, but your guest operating system does not have connectivity, it may be a problem with your iptables configuration. libvirtd should have created a number of iptables rules when it was installed.
In particular, list your iptables nat table:
sudo iptables -t nat -L
You should see:
...
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- 192.168.122.0/24 !192.168.122.0/24
...
If this rule is missing, you can try to recreate it by:
Stop all of your virtual machines
Destroy and recreate the default network:
virsh net-destroy default
virsh net-start default[/list]
meine ausgabe
# iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- 192.168.122.0/24 !192.168.122.0/24
fehlt bei mir.
# virsh net-destroy default
error: Failed to destroy network default
error: internal error network is not active
wenn ich die VM mit der Kommandozeile erstelle hat diese auch Netzwerkverbindung zu eth0
aber ich würde es trotzdem gerne mit dem Virtual machine manager zum laufen bekommen!!:evil:
