I also tried creating new virtual networks with virt-manager as both
"Isolated virtual network" and "Forwarding to physical network". Each
time I ping the host's virtual interface which is on the same subnet
as the guest's eth0, it fails. On doing a tcpdump on host's virtual
interface(vnet2), I see that the guest's ARP *is* coming through, but
the host is unable to resolve guest's eth0 IP (192.168.99.128 below).
Host's virtual IP is 192.168.99.1.

[root at fed-amd64 ~]# tcpdump -i vnet2
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vnet2, link-type EN10MB (Ethernet), capture size 96 bytes
01:24:52.588689 arp who-has 192.168.99.128 tell 192.168.99.1
01:24:53.588448 arp who-has 192.168.99.128 tell 192.168.99.1
01:24:54.588226 arp who-has 192.168.99.128 tell 192.168.99.1


Like before it's failing on the ARP. Any pointers greatly appreciated.

Thanks,
