Hello all, Basically my problem is how can i access a virtual machine from local network. I am able to do so from the host PC put not from other PC's on the same network. here is my what i did so far (http://wiki.libvirt.org/page/Networking#NAT_forwarding_.28aka_.22virtual_...) cat '/etc/libvirt/qemu/networks/default.xml' <network> <name>default</name> <uuid>1bad08f7-0bc3-bfde-f87d-f323ab1c95eb</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0' /> <ip address='10.0.2.1' netmask='255.255.255.240'> <dhcp> <range start='10.0.2.2' end='10.0.2.14' /> </dhcp> </ip> </network> cat '/etc/sysctl.conf' # Disable packet forwarding #net.ipv4.ip_forward=0 net.ipv4.ip_forward=1 # disable netfilter on the bridge: net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 ifconfig -a br0 Link encap:Ethernet HWaddr 00:1C:C0:38:AF:BA inet addr:10.0.1.5 Bcast:10.0.1.15 Mask:255.255.255.240 inet6 addr: fe80::21c:c0ff:fe38:afba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:580 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:29435 (28.7 Kb) TX bytes:468 (468.0 b) eth0 Link encap:Ethernet HWaddr 00:C0:DF:13:AF:87 inet addr:10.0.1.4 Bcast:10.0.1.15 Mask:255.255.255.240 inet6 addr: fe80::2c0:dfff:fe13:af87/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:476362 errors:0 dropped:0 overruns:0 frame:0 TX packets:684752 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:57147388 (54.4 Mb) TX bytes:707797829 (675.0 Mb) Interrupt:22 Base address:0x800 eth1 Link encap:Ethernet HWaddr 00:1C:C0:38:AF:BA inet6 addr: fe80::21c:c0ff:fe38:afba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1142 errors:0 dropped:0 overruns:0 frame:0 TX packets:43 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:90530 (88.4 Kb) TX bytes:2632 (2.5 Kb) Memory:e3200000-e3220000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:118356 errors:0 dropped:0 overruns:0 frame:0 TX packets:118356 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14239239 (13.5 Mb) TX bytes:14239239 (13.5 Mb) virbr0 Link encap:Ethernet HWaddr FE:54:00:45:A7:31 inet addr:10.0.2.1 Bcast:10.0.2.15 Mask:255.255.255.240 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:180 errors:0 dropped:0 overruns:0 frame:0 TX packets:128 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16657 (16.2 Kb) TX bytes:50599 (49.4 Kb) vnet0 Link encap:Ethernet HWaddr FE:54:00:45:A7:31 inet6 addr: fe80::fc54:ff:fe45:a731/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:357 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:1404 (1.3 Kb) TX bytes:19248 (18.7 Kb) brctl show bridge name bridge id STP enabled interfaces br0 8000.001cc038afba no eth1 virbr0 8000.fe540045a731 yes vnet0 route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.1.0 0.0.0.0 255.255.255.240 U 0 0 0 eth0 10.0.1.0 0.0.0.0 255.255.255.240 U 0 0 0 br0 10.0.2.0 0.0.0.0 255.255.255.240 U 0 0 0 virbr0 0.0.0.0 10.0.1.1 0.0.0.0 UG 0 0 0 eth0 iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 10.0.2.0/28 state RELATED,ESTABLISHED ACCEPT all -- 10.0.2.0/28 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- anywhere anywhere PHYSDEV match --physdev-is-bridged ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere 10.0.2.5 tcp dpt:smakynet ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere 10.0.2.5 tcp dpt:smakynet ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere 10.0.2.5 tcp dpt:smakynet Chain OUTPUT (policy ACCEPT) target prot opt source destination the IP Address for the virtual machine i am trying to access is 10.0.2.5 (vnet0). I am able only to access it from the host PC only, therefore, how i can i access it from other PC's on the network ? Any help would be much appreciated. -- Sincerely,
