Title:
instances created in newly created subnet are not accessible via
private range ip adress 10.0.11.2 from devstack host machine
Status in OpenStack Neutron (virtual network service):
Expired
Bug description:
we have single node devstack (branch: stable/grizzly) installation.
subnet list:
first is subnet of default "private" network subnet
| 6ea6f812-3ad4-4414-ba9e-d57a44ae15cc | |
10.0.55.0/24 | {"start": "10.0.55.2", "end": "10.0.55.254"} |
| da7ad45b-6b92-426e-8c6b-1453f271e350 | not_working_subnet | 10.0.11.0/24
| {"start": "10.0.11.2", "end": "10.0.11.254"} |
not_working_subnet is connected to a router which is also connected to
public network via its gateway inerface
when creating VM in "private" network them is accessible (ping, ssh) from
devstack host machine on its ip e.g. 10.0.55.2.
if i create VM in "not_working_subnet" then is not accessible via its ip e.g.
10.0.11.2.
We have found problem is probably that routing table of devstack host
machine is missing route routing packets to router gateway interface.
I added bellow route then instnances on not_working_subnet are also
accessible from host machine and everything works fine
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.11.0 XX.YY.ZZ.205 255.255.255.0 UG 0 0 0 br-ex
route for private network is already present therefore for private
network everything works fine
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.55.0 XX.YY.ZZ.194 255.255.255.0 UG 0 0 0 br-ex
We assume that routing table of host machine should get automatically updated
when subnet created with connection to public network via router.
