I'm pretty new to networking and just can't get my head around this.
I'm trying to setup KVM-Qemu so I can run some virtual machines. The instructions I'm following are telling me to use eth0 and eth1 as local and WAN connections. I only have eth0 which is used for WAN. I created (or tried to) eth1 and the appropriate bridging, but this keeps disconnecting me from the server when I restart the network interfaces.
Any idea how I can fix this, as I only have eth0?
The instructions are here:
For the bridging, I'm using the settings that my host has provided me with for the additional IP.
Starting eth0 configuration:
##Note for customers who want to create bridged networking for virtualisation: ##Gateway is set in separate file ##Do not forget to change interface in file route-eth0 and rename this file device: eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes HWADDR=50:46:5d:xx:xx:xx IPADDR=144.76.xx.xxx NETMASK=255.255.255.255 SCOPE="peer 144.76.yy.yyy" IPV6INIT=yes IPV6ADDR=2a01:4f8:191:7282::2/64 IPV6_DEFAULTGW=fe80::1 IPV6_DEFAULTDEV=eth0
At this point eth1 doesn't exist (though instructions say it should).
Then I create eth1 from instructions:
DEVICE=eth1 ONBOOT=yes HWADDR=00:30:48:C6:0A:D9 BRIDGE=br1
Then I add the bridges:
DEVICE=br0 TYPE=Bridge BOOTPROTO=static ONBOOT=yes ## setup LAN/VLAN ips as per your needs ## IPADDR=10.10.29.66 NETMASK=255.255.255.192 DELAY=0 DEVICE=br1 TYPE=Bridge BOOTPROTO=static ONBOOT=yes ## setup INTERNET ips as per your needs ## IPADDR=74.ww.xx.yy NETMASK=255.255.255.248 GATEWAY=74.ww.xx.yy DELAY=0
(I replace the bridge specific settings with those that my host has provided for br1)
Then I restart the network and it fails.
Any ideas? :)
