| 20:45:26 | efried | or get to the console. I don't really even need networking for what I'm doing. | |
| 20:45:37 | efried | (It's kind of embarrassing that I've basically never done this) | |
| 20:45:55 | sean-k-mooney | you have never done a nova boot? | |
| 20:46:12 | sean-k-mooney | or actully tried to ssh in after | |
| 20:46:58 | efried | the latter | |
| 20:47:04 | artom | efried, paste? | |
| 20:47:23 | efried | artom: As in, I might be able to help you with your paste/middleware | |
| 20:47:47 | efried | sean-k-mooney: never cared about the VM itself, just about the bits that get it to ACTIVE state. | |
| 20:49:08 | sean-k-mooney | to enable dhcp do "openstack subnet set --dhcp public" | |
| 20:49:29 | sean-k-mooney | you then need to open ssh in the security groups | |
| 20:51:42 | sean-k-mooney | "openstack security group rule create --ingress --protocol tcp --remote-ip 0.0.0.0/0 default" | |
| 20:51:56 | sean-k-mooney | if you reboot the vm you should then be able to ssh in with | |
| 20:52:26 | sean-k-mooney | openstack server ssh --private -l cirros <vm name> | |
| 20:52:28 | artom | efried, ah, thanks! Tomorrow? If it's still bugging me then | |
| 20:52:34 | efried | artom: sure thing | |
| 20:52:35 | artom | I'm on the hook for the school run now | |
| 20:52:44 | efried | me too in 20 mins | |
| 20:53:06 | eandersson | Fighting heal_allocations is never fun | |
| 20:53:23 | eandersson | I almost wish it was out of tree | |
| 20:54:21 | efried | sean-k-mooney: is it gonna hurt me that my VM currently doesn't think it has an ipv4 address? | |
| 20:54:48 | sean-k-mooney | you dont see one in openstack server show our you cant ping it | |
| 20:57:10 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Use admin neutron client to gather port resource requests https://review.opendev.org/691005 | |
| 20:57:10 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Use admin neutron client to query ports for binding https://review.opendev.org/690999 | |
| 20:57:11 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Use admin neutron client to see if instance has qos ports https://review.opendev.org/691900 | |
| 20:57:31 | sean-k-mooney | efried: if you just want the console url you can do "openstack console url <vm name>" by the way | |
| 20:57:40 | efried | sean-k-mooney: per the console running ifconfig -a | |
| 20:58:01 | sean-k-mooney | oh did you enable dhcp like i said and reboot | |
| 20:58:09 | efried | yeah, the console via browser is pretty clunky, I could make do with that but would rather be able to ssh | |
| 20:58:27 | efried | for one thing, it seems to be bypassing my keyboard driver | |
| 20:58:33 | efried | I can't type qwerty to save my life | |
| 20:58:44 | sean-k-mooney | davorak? | |
| 20:59:05 | efried | there were three security groups, so I set that up for all of them, cause I didn't know which one was the right one. rebooting the vm now | |
| 20:59:08 | efried | yes, dvorak | |
| 20:59:13 | efried | for nearly 20 years. | |
| 20:59:25 | sean-k-mooney | ... i see | |
| 20:59:33 | sean-k-mooney | anyway am if your in the vm | |
| 20:59:42 | efried | can't imagine how a console through a browser is using its own kb driver | |
| 20:59:47 | mriedem | note that those 3 fixes above are gibi's and pretty straight-forward | |
| 20:59:48 | efried | but whatever | |
| 20:59:50 | mriedem | i'm +2 on all 3 | |
| 21:01:06 | sean-k-mooney | efried: so anyway your in the vm right. have you enabled dhcp on the subnet? if so you can reboot and it should get an ip or you can run cirros dhcpclient directly | |
| 21:01:14 | sean-k-mooney | efried: then you should be able to ssh in | |
| 21:01:34 | efried | rebooting, waiting for it to come up | |
| 21:02:07 | sean-k-mooney | efried: i usually put the command to do this in a local.sh file beside my local.conf | |
| 21:02:09 | mriedem | efried: are you just trying to figure out how to ssh into a cirros guest in devstack? | |
| 21:02:12 | sean-k-mooney | i just cant find it | |
| 21:02:28 | mriedem | i've got a recording on youtube that does that with a floating ip | |
| 21:02:29 | sean-k-mooney | devstack will auto run the local.sh if present | |
| 21:02:36 | efried | openstack server reboot | |
| 21:02:36 | efried | openstack security group rule create --ingress --protocol tcp --remote-ip 0.0.0.0/0 $group for all three groups | |
| 21:02:36 | efried | openstack subnet set --dhcp public-subnet | |
| 21:02:36 | efried | I did | |
| 21:02:47 | efried | mriedem: yes, that's what I'm trying to do. | |
| 21:02:50 | sean-k-mooney | yep that should be enough | |
| 21:02:58 | mriedem | heh, it's been like 3 days :) | |
| 21:02:58 | mriedem | sec | |
| 21:03:39 | mriedem | efried: it's a bit old, but this shows setting up a guest in devstack with a floating ip to ssh into it https://www.youtube.com/watch?v=hZg6wqxdEHk | |
| 21:03:58 | sean-k-mooney | ... my clean vm failed because i forget to mount /opt on a cinder volume and ran out of space :( | |
| 21:04:25 | efried | thanks mriedem, will try that on my other devstack | |
| 21:04:42 | efried | ssh: connect to host 2001:db8::109 port 22: No route to host | |
| 21:04:42 | efried | stack@nucle:/opt/stack/devstack$ openstack server ssh --private -l cirros test1 | |
| 21:04:42 | efried | sean-k-mooney: | |
| 21:04:54 | sean-k-mooney | add -4 | |
| 21:04:59 | mriedem | start about 3 minutes in | |
| 21:05:04 | mriedem | ignore all of the volume multiattach stuff | |
| 21:05:06 | sean-k-mooney | unless you have routable ipv6 | |
| 21:05:27 | sean-k-mooney | if you do you need to change teh --remote-ip to allow ipv6 trafic | |
| 21:05:56 | sean-k-mooney | efried: you cans also just use ssh directly if you know the ip | |
| 21:06:06 | efried | ah, but I can ssh to the IP... yes | |
| 21:06:22 | efried | I don't think I can ipv6 at all | |
| 21:06:49 | ioni | g like lxd/openvz | |
| 21:06:49 | ioni | hello guys, i'm using openstack in production and also sadly still use openvz and i plan to move away from it in the near future. is there a project that i can use with openstack to orchestrate containers like openvz. lxd seems the same but nova-lxd is not maintained anymore and everything that i can find related to openstack and containers is mostly related to docker and kubernets but not somethin | |
| 21:07:01 | efried | adding -4 also made the openstack command work | |
| 21:07:11 | sean-k-mooney | efried: the firewall is blocking all ipv6 into the vm by default | |
| 21:07:19 | mriedem | ioni: zun | |
| 21:07:31 | efried | sokay, I'm pretty sure ipv6 is never going to catch on anyway. I'll just use v4 | |
| 21:07:34 | efried | thanks for the help, again. | |
| 21:08:09 | sean-k-mooney | haha i spend like a full weekend getting it working at home like a month ago | |
| 21:08:48 | sean-k-mooney | i dont have native ipv6 at home so had to set up tunneling and then route it into openstack so that my vms get public ipv6 adresses | |
| 21:08:55 | mriedem | "how do i ssh into a guest in devstack" <3 days later> "wait, you don't need ipv6 with numa and dpdk? oh, well then..." | |
| 21:09:35 | sean-k-mooney | :) | |
| 21:09:47 | sean-k-mooney | mriedem: actully regarding multi attach | |
| 21:09:51 | mriedem | stop | |
| 21:09:56 | sean-k-mooney | what file system do you use? | |
| 21:10:08 | mriedem | in this demo? | |
| 21:10:12 | sean-k-mooney | in general | |
| 21:10:18 | mriedem | i don't | |
| 21:10:22 | sean-k-mooney | i dont think we mention it in the docs | |
| 21:10:24 | sean-k-mooney | ok | |
| 21:10:33 | mriedem | multiattach docs are mostly in cinder | |
| 21:10:47 | sean-k-mooney | ah o should read those at some point | |
| 21:11:04 | mriedem | https://docs.openstack.org/cinder/latest/admin/blockstorage-volume-multiattach.html | |
| 21:11:07 | mriedem | doesn't really go into details either | |
| 21:11:15 | ioni | mriedem, zun seems that it uses docker and is not something that i can replace openvz with | |
| 21:11:29 | sean-k-mooney | i was thinking of using it for k8s on openstack but it seamed complicated | |
| 21:11:30 | mriedem | efried: so about 9 minutes into that demo i'm creating a floating ip for the port attached to the server | |
| 21:13:00 | mriedem | might be useful if i just wrote this up into devstack docs | |
| 21:13:27 | sean-k-mooney | mriedem: i think there used to be an exersie that coverd it | |
| 21:13:36 | sean-k-mooney | but i cant find it | |
| 21:14:00 | mriedem | ioni: nova isn't really big on containers, it's basically vms and a front end for ironic baremetal, | |
