Re: [Openstack] network question on openstack installation

It depends on your switch… some drop tagged packets on an access port, others allow tagged packets, if the packet VLAN ID equals the configured VLAN ID. I'd reconfigure the provider network type to "flat" but that's personal taste. You could also reconfigure the switch port to be a trunking port

Re: [Openstack] network question on openstack installation

thank you, Uwe. our provider network actually is untagged, but I did specified VLAN ID when I create our external network and everything still works. will this cause issue later on? eutron net-create --provider:network_type=vlan —provider:segmentation_id= --provider:physical_network=physnet1 --r

Re: [Openstack] network question on openstack installation

Hi Yang, it depends on whether your provider network is tagged or untagged. If it is untagged (the switch port is an "access" port) then you don't specify the VLAN ID for the external network (as it will get tagged by the switch). If the provider network is tagged (the switch port is a "trunk" p

Re: [Openstack] network question on openstack installation

Thank you so much, James! This is so helpful. Another confusion I have is about network_vlan_ranges. Is this network VLAN id range? If so, does it has to match external network? For example, we only have one external VLAN we can use as Our provider network and that VLAN id is 775 (xxx.xxx.xxx.0/

Re: [Openstack] network question on openstack installation

One way would be to achieve this via "Availabilty zones". Just create 2 host aggregates (and with it a such a zone) and add a hypervisor to each of them (host aggreate to availability zone is 1:1 mapping) The instance launch dialog allows you to select the zone. Hope this helps On Fr, 2015-06-2

Re: [Openstack] network question on openstack installation

You can absolutely have instances in the same network span different compute nodes. As an admin, you can run ‘nova show ’ and see the host in the output: root@controller01:~# nova show 7bb18175-87da-4d1f-8dca-2ef07fee9d21 | grep host | OS-EXT-SRV-ATTR:host | compute02
