Hi,
It seems vmcontext scripts try to guess the gateway IP as soon as any
interface has a gateway set.
Here is my case:
one vm with eth0 to internal admin network, and eth1 to wan. Only eth1 has
a gateway set.
When init script vmcontext start, it found out that there is a gateway (but
on eth1), and so is_gateway function on eth0 seems to returns true. After
that the gateway is guessed with NETWORK_ADDRESS.1 but I don't know why?
here is my context:
ETH0_IP='192.168.199.109'
ETH0_MAC='02:00:c0:a8:c7:6d'
ETH1_DNS='10.156.255.245'
ETH1_GATEWAY='10.156.0.1'
ETH1_IP='10.156.24.93'
ETH1_MAC='02:00:0a:9c:18:5d'
ETH1_MASK='255.255.224.0'
ETH1_NETWORK='10.156.0.0'
Here is the ifcfg-eth0 written by vmcontext init script:
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=192.168.199.109
GATEWAY=192.168.199.1
ifcfg-eth1 is good and has its gateway correctly set.
Here is my vnet template where no gateway is set (same problem if I remove
the empty GATEWAY key):
VIRTUAL NETWORK TEMPLATE
BRIDGE="br0"
DESCRIPTION="réseau admin vm"
GATEWAY=""
PHYDEV=""
ROLE="admin"
VLAN="YES"
VLAN_ID="199"
is it a bug?
Attached here is the vmcontext network script log
best regards,
Edouard
