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_networks.22.29)
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

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.
