Ho spostato una vecchia installazione di Slackware 11 da un PC fisico a una virtualizzata in ESXi.
Tutto sembra funzionare bene tranne una regola in iptables, vale a dire la riga:
iptables -t filter -I INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
Il ritorno da iptables è: iptables: errore sconosciuto 4294967295
Il mio googling mi porta solo a problemi quando utilizzo openVZ.

Qualche pensiero?
