Hello,
I'm fairly new to Ubuntu (and linux). I'm attempting to do a very basic VM setup using KVM to create a centos7 box. This machine is unable to connect to the internet. Pretty much every site says "it should just work auto-magically!" I've been banging my head against a wall trying to figure out why its not for me. ](*,)
About the only thing I can do from the guest is ssh to the host. However, the host cannot ssh to guest (no open-ssh installed yet).
guest = app02@localhost
host = drew@drewbuntu
GUEST INFO
ifconfig
iptables -L on guest
Attempt to ssh to guest
HOST INFO
ifconfig
cat /proc/sys/net/ipv4/ip_forward
/etc/network/interfaces on host
iptables -L on host
kernal: 4.8.0-44-generic
I have attempted these troubleshooting steps already: https://help.ubuntu.com/community/KV...roubleshooting
I've got to be missing something stupid-easy...
