Proxmox - single public ip with multiple vms, openvz containers work, kvm's don't have a route
Currently I only have a /30 block (1 usable IP) (I just ordered a /28 for 13 usable publics, waiting)
I just installed proxmox, set up a few virtual containers. Port forwarded the necessary services/ports. All is working. But when I load up a KVM I can't seem to identify what I'm doing wrong to only get outgoing connections, or even no connections.
All containers have the lan ip set and a veth0 device bridged to vmbr1 The KVM has a bridged network device to vmbr1 set as well (no where to dictate its lan ip in proxmox like the containers, this is where I think my problem is)
here's the /etc/network/interfaces
for the kvm
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
address 192.168.0.102
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.25
gateway 192.168.0.254
dns-nameserver 8.8.8.8
dns-search 8.8.8.8
heres the /etc/network/interfaces
for the host

I had the wrong ip address for the vmbr1 and in turn the wrong gateway for the kvm eth0 interface config
corrected kvm /etc/network/interface
iface eth0 inet static
address 192.168.0.102
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.25
gateway 192.168.0.1
corrected host /etc/network/interface
iface vmbr1 inet static
address 192.168.0.1
netmask 255.255.255.0
