masbergodo morning01:44
masbergood morning all01:44
masberI am playing with Ironic and wanted to ask. Can I use as user image the cloud images I used to deploy vms?01:45
masberfor some reason, the deployment of the node is successful but I can't login into it and can't ping its IP01:46
masberany thoughts?01:46
TheJuliamasber: sounds like maybe configuration drives are not being written _or_ there is no meta data service02:15
TheJuliamasber: there is another possibility, the VM images could lack something like the network card drivers02:16
masberTheJulia, ok, one thing I realised is that dnsmasq is not receiving any DHCP notification02:16
TheJuliaOn your tenant network, I guess that would make sense of02:16
masberI am using provider network02:16
masberalso I am using port group but I don't know how it works, I mean is ironic configuring the nic bonding for me?02:17
TheJuliamasber: what is the network_interface set to?02:18
TheJuliafor the node in ironic?02:18
masberopenstack baremetal node show zeus-54 | grep network_interface --> flat02:19
TheJuliaso port groups won't work, you'll need to use the neutron network_interface for that02:20
TheJuliabut that requires switch integration02:20
masberoh02:20
TheJulianeutron network_interface == switch ml2 drviers + tenant networking02:20
masberwhat "switch integration" means?02:21
TheJuliayou can technically do portgroups with flat, but they need to be pre-configured on the switch02:21
TheJuliaby switch integeration, I mean there is an ml2 driver that controls the switch port binding02:23
masberI am not sure if I fully understand but I think the switch is already configured to support bonding mode=802.3ad what I mean is that I have to configure the  mode=802.3ad bonding on the host if I want to use that network02:35
masberdoes it means the switch is pre-configured?02:35
masberapologize for the stupid questions02:36
TheJuliamasber: In essence, flat means all networking is preconfigured and static02:43
TheJuliaexcept dhcp02:43
TheJuliaSo it goes beyond the switch supporting 802.3ad, it the ports need to be configured in advance to be in the bond you desire02:44
TheJuliamasber: It is perfectly alright, this is a complex subject02:46
masberok02:50
masberthen the switch is already setup02:50
masberhum02:50
masberbut is ironic going to setup the bonding on the host? if yes, how? is IPA doing that?02:51
TheJuliaIronic passes the info to neutron02:53
TheJuliacloud-init or... "glean" if installed would set it up02:54
TheJuliabut that is during the first boot of the new geust os02:54
masberok02:55
masbermy problem is that I can't ssh to the node because the IP is not accessible.02:58
masberI would like to access the node to see the network configuration and see what is wrong. Is there a way to access cloud-init logs to check the network configuration is is doing?02:59
*** dsneddon has quit IRC03:08
TheJuliamasber: typically people prepare a special image to deploy that has a user pre-configured (like using diskimage-builder and the devuser element option). Once deployed, they login to troubleshoot from there03:18
TheJulialogin from the console that is03:18
*** dsneddon has joined #openstack-ironic03:34
masberAnother question. I also tried ssh into the PXE nic but it complains saying "Permission denied (publickey,gssapi-keyex,gssapi-with-mic)."03:39
*** bfournie has quit IRC03:40
*** dsneddon has quit IRC03:50
TheJuliaDid you try as the image's cloud user?04:03
TheJuliaLike "ubuntu" or "centos"04:03
masberTheJulia, yes04:06
masberthis is a centos 7 cloud image, I tried login as centos user04:06
TheJuliamasber: sounds like your at the point where you need to burn a user into the image your deploying to investigate further04:07
masberok, will try that. thank you for all your help :)04:13
