I've just installed a XenServer 6.1. It came with a standard configuration, network 0 connected to NIC 0.
I created a VM but I can't reach any network beyond the host.
From the VM (172.18.32.20), I try to ping 172.18.32.254.
Trying to make it work, I brought the following changes to the host base configuration:
- xe-switch-network-backend bridge
net.ipv4.ip_forward = 1 net.ipv4.icmp_echo_ignore_broadcasts = 1 net.ipv4.conf.all.arp_filter = 1 net.ipv4.conf.default.proxy_arp = 1
- stop iptables
iptables -A FORWARD -j ACCEPT
"Ifconfig -a" shows 4 interfaces: eth0, lo, vif12.0 (my VM) and xenbr0 (IP=172.18.32.10, netmask=255.255.255.0, gateway=188.8.131.52)
$ brctl show bridge name bridge id STP enabled interfaces xenbr0 5000.042b21457249 no eth0 vif12.0
After all that, my VM still can ping 172.18.32.10 but not 172.18.32.254.
The host can ping it.
Can someone tell me how to proceed and if bridging is the right thing to do?
