To be more specific, I'm doing a tcpdump on guest's
eth0(192.168.122.195). When the host pings 192.168.122.195, I see
following -
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
12:15:49.058031 arp who-has 192.168.122.195 tell 192.168.122.1
12:15:51.065437 arp who-has 192.168.122.195 tell 192.168.122.1
12:15:52.069123 arp who-has 192.168.122.195 tell 192.168.122.1
12:15:53.071852 arp who-has 192.168.122.195 tell 192.168.122.1
12:15:55.077218 arp who-has 192.168.122.195 tell 192.168.122.1
When the guest's eth0 is receiving ARP for it's right IP address, why
is it not responding?
Here are the routing tables -

[root@fed-amd64 ~]# netstat -rn

Please ignore this. I figured that I have to use host's
eth0(192.168.1.9) to access the host from the guest.
