Hiho, hab nen Rootserver auf welchem ich gerade frisch opensuse 10.1 installiert habe. Als Guest nutze ich ein Debian 4 (etch).

Ich nutze den vorgefertigten Kernel und die Toolz von Openvz.org.

Vielleicht solltest du mal überprüfen, ob eine Paketfirewall an ist und diese ggf. ausschalten.

Hi,

hat die VE korrekte DNS Einstellungen:

* /etc/resolv.conf hat gültige Einträge und die DNS Server sind erreichbar ?

* keine /etc/resolv.conf vorhanden ?
VE_0_# vzctl set <VEID> --nameserver <ip.des.1ten.dns> --nameserver <ip.des.2ten.dns> ... --searchdomain <domain> [--save]

ARGH, ICH BIN SO EIN BLINDES HUHN.

Man sollte seine zugewiesene IP-Adresse auch richtig eintippen. Hatte nen Zahlendreher drin und nu klappt's auch mit dem Inetzugriff.
