I have my laptop running Fedora 18. I want to run a Windows XP guest using VirtualBox 4.2.6. My configuration seems correct, hereis my networking report.Fedora 18 hostlo: flags=73<UP,LOOPBACK,RUNNING>  mtu 16436    inet 127.0.0.1  netmask 255.0.0.0    inet6 ::1  prefixlen 128  scopeid 0x10<host>    loop  txqueuelen 0  (Local Loopback)    RX packets 72  bytes 6640 (6.4 KiB)    RX errors 0  dropped 0  overruns 0  frame 0    TX packets 72  bytes 6640 (6.4 KiB)    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0p2p1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500    ether 00:1e:68:68:11:93  txqueuelen 1000  (Ethernet)    RX packets 0  bytes 0 (0.0 B)    RX errors 0  dropped 0  overruns 0  frame 0    TX packets 0  bytes 0 (0.0 B)    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0    device interrupt 16  ppp0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 1500    inet 10.231.243.74  netmask 255.255.255.255  destination 10.20.31.30    ppp  txqueuelen 3  (Point-to-Point Protocol)    RX packets 36895  bytes 35633124 (33.9 MiB)    RX errors 2  dropped 0  overruns 0  frame 0    TX packets 42421  bytes 3077319 (2.9 MiB)    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0vboxnet0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500    inet 192.168.56.1  netmask 255.255.255.0  broadcast 192.168.56.255    inet6 fe80::800:27ff:fe00:0  prefixlen 64  scopeid 0x20<link>    ether 0a:00:27:00:00:00  txqueuelen 1000  (Ethernet)    RX packets 0  bytes 0 (0.0 B)    RX errors 0  dropped 0  overruns 0  frame 0    TX packets 348  bytes 41858 (40.8 KiB)    TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0As for my XP guest, the IP address is 192.168.56.2. On the network setup I've choosen the host-only adapter with vboxnet0. Yetwhen I perform a ping from my Fedora host, it doesn't yield any reply.[root@laptop Downloads]# ping 192.168.56.2PING 192.168.56.2 (192.168.56.2) 56(84) bytes of data. //here is should be reply answer from blablabla, like in most normal ping route -n command on the Fedora 18 host resultKernel IP routing tableDestination     Gateway         Genmask         Flags Metric Ref    Use Iface0.0.0.0         10.20.31.7      0.0.0.0         UG    0      0        0 ppp010.20.31.7      0.0.0.0         255.255.255.255 UH    0      0        0 ppp0192.168.56.0    0.0.0.0         255.255.255.0   U     0      0        0 vboxnet0and also my guest windows xp route print commands yields===========================================================================Interface List0x1 ...........................
