[rdo] [packstack] failing to setup Stein with Openvswitch/VXLAN networking
Trying to set up a Stein cloud with Packstack. I want the Openvswitch mech driver and VXLAN type driver. A few weeks ago, the following invocation was successful:
|sudo packstack --debug --allinone --default-password pw \ --os-neutron-ovs-bridge-interfaces=br-ex:eth0 \ --os-neutron-ml2-tenant-network-types=vxlan \ --os-neutron-ml2-mechanism-drivers=openvswitch \ --os-neutron-ml2-type-drivers=vxlan,flat \ --os-neutron-l2-agent=openvswitch \ --provision-demo-floatrange=10.1.1.0/24\ --provision-demo-allocation-pools '["start=10.1.1.10,end=10.1.1.50"]'\ --os-heat-install=y --os-heat-cfn-install=y|||
Now, it fails during network setup. My network connection to the Packstack server is severed, and it turns out that its only network interface /eth0 /has no IP address and is down. No bridge exists.
In the /network.pp.finished /file, I find various /ovs-vsctl /commands including /add-br/, and a command /ifdown eth0 /which fails with exit code 1 (no error message from the /ifdown /command is logged).
*Can somebody recommend the options required to successfully deploy a Stein cloud based on the Openvswitch and VXLAN drivers?*
Thanks much,
Bernd

Hi,
So, IIUC, your server has a single NIC, eth0, right?
Could you provide the configuration file for eth0 before running packstack?, i guess you are using ifcfg files?
Best regards,
Alfredo

Thanks Alfredo. Yes, a single eth0:
$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 ... 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 52:54:00:dd:2c:f3 brd ff:ff:ff:ff:ff:ff inet 192.168.1.202/24 brd 192.168.1.255 scope global eth0 valid_lft forever preferred_lft forever inet6 240d:1a:3c5:3d00:5054:ff:fedd:2cf3/64 scope global mngtmpaddr dynamic valid_lft 10790sec preferred_lft 10790sec inet6 fe80::5054:ff:fedd:2cf3/64 scope link valid_lft forever preferred_lft forever
and ifcfg-eth0 is unchanged since installation (perhaps I should clean it up a little; could IPv6 be causing problems?):
$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eth0 UUID=75c26b23-f3fb-4d3f-a473-5354075d5a25 DEVICE=eth0 ONBOOT=yes IPADDR=192.168.1.202 PREFIX=24 GATEWAY=192.168.1.1 DNS1=192.168.1.16 DNS2=1.1.1.1 DOMAIN=home IPV6_PRIVACY=no
More info: This is a VM running /CentOS 7.6.1810 /on a Fedora KVM host. eth0 is bridged. I did disable and stop network manager and firewalld on the guest.

Hmmmmm. I just succeeded in setting up my Packstack after removing IPv6 from the kernel and cleaning out ifgcfg-eth0. Since I don't need IPv6, I am good. My config:
$ *cat /etc/sysconfig/network-scripts/ifcfg-eth0* TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=192.168.1.202 PREFIX=24 GATEWAY=192.168.1.1 DNS1=192.168.1.16 DNS2=1.1.1.1 DOMAIN=home IPV6INIT=no $ *cat /etc/sysctl.conf* net.ipv6.conf.eth0.disable_ipv6=1
Thanks again, Alfredo.
