Thanks for your reply Dag, it seems I can't ping the gateway. Some
background on the setup which I should've explained earlier:
Running Cloudstack 4.9 with KVM on Ubuntu 14.04, it's a single machine
setup with the vms and management on the same host. Here's the network
interface:
# The primary network interface
auto eth0
iface eth0 inet manual
# Public network
auto cloudbr0
iface cloudbr0 inet static
address 172.16.135.130
netmask 255.255.254.0
gateway 172.16.135.254
dns-nameservers 172.16.238.7 172.16.238.6
dns-domain UTP.EDU.MY
bridge_ports eth0
bridge_fd 5
bridge_stp off
bridge_maxwait 1
# Private network
auto cloudbr1
iface cloudbr1 inet manual
bridge_ports none
bridge_fd 5
bridge_stp off
bridge_maxwait 1
Here's the ssvm interface:
auto lo eth0 eth1 eth2
iface lo inet loopback
iface eth0 inet static
address 169.254.0.105
netmask 255.255.0.0
iface eth1 inet static
address 172.16.135.24
netmask 255.255.254.0
iface eth2 inet static
address 172.16.135.154
netmask 255.255.254.0
I've disabled firewall to ensure that it's not the problem and so it
doesn't interfere in fixing this. I'll set that up later. I'm thinking my
problem might be my configuration. I've configured the External and
Internal DNS as the dns nameservers from the interface. I'm not sure if the
ACL might be blocking the traffic, but I will check into that. But, I do
not think that might be the problem as currently I can ping the dns and the
gateway from the host, just not from the ssvm.
Looking forward to your reply
