Is it possible to configure 2 virtual nics in the same ip range ? Here is what I am trying. **** This works ****************
cat nw1.xml
<network>
<name>nw1</name>
<domain name='nw1' />
<forward mode='nat' dev='eth2'/>
<ip address='192.168.101.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.101.128' end='192.168.101.254'/>
</dhcp>
</ip>
</network>
[root@localhost nw]# virsh net-create nw1.xml
Network nw1 created from nw1.xml
[root@localhost nw]# virsh net-list --all
Name State Autostart Persistent
----------------------------------------------------------
nw1 active no no
default active yes yes
****** FAILS when given the same ip address range of an existing virtual interface *******
[root@localhost nw]# cat nw2.xml
<network>
<name>nw2</name>
<domain name='nw2' />
<forward mode='nat' dev='eth2'/>
<ip address='192.168.101.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.101.128' end='192.168.101.254'/>
</dhcp>
</ip>
</network>
[root@localhost nw]# virsh net-create nw2.xml
error: Failed to create network from nw2.xml
error: internal error: Network is already in use by interface virbr1
****** PASS - on giving diff ip range *******
[root@localhost nw]# cat nw3.xml
<network>
<name>nw3</name>
<domain name='nw3' />
<forward mode='nat' dev='eth2'/>
<ip address='192.168.102.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.102.128' end='192.168.102.254'/>
</dhcp>
</ip>
</network>
[root@localhost nw]# virsh net-create nw3.xml
Network nw3 created from nw3.xml
[root@localhost nw]# virsh net-list --all
Name State Autostart Persistent
----------------------------------------------------------
nw1 active no no
nw3 active no no
default active yes yes
Any suggestions on what could be wrong here ?
Thanks,
G
