ryanpetrellodrwahl: so this *is* still an issue if we're having issues w/ load01:59
ryanpetrellomeaning if the rug is super backed up01:59
ryanpetrelloinstances that boot won't get DHCP because the rug won't have reconfigured dnsmasq on the router VM yet01:59
ryanpetrelloI'm all for brainstorming on this, though02:00
ryanpetrelloin the past we had discussed making dhcp something that could generated on the fly rather than requiring a router push02:00

markmcclainryanpetrello: yes there are a few ways to solve this.. either make the akanda instance relay DHCP back to the rug or make the DHCP server smarter and fetch on a config miss or make the L2 agent the request14:13
markmcclainthe last method also ensures that DHCP works on segments without routers attached14:13
markmcclainand additionally means that DHCP now shares fate with the HV14:14

adam_gnow to figure out how to make the appliance VM boot faster16:22
ryanpetrello\o/16:23
adam_gthe router VMs boot really slow with non-accelerated qemu16:24
ryanpetrelloye16:24
ryanpetrello*yep16:24
adam_gIIRC its blocking mostly at the pre-mount or post-mount stage of the initrd16:24
adam_gi feel like i did something at one point with other DIB images to fix that but dont remember what it was16:24
adam_gmarkmcclain, thoughts on dropping the provider_rules.json stuff? i cant find any evidence of it serving a purpose16:40

markmcclainadam_g: so while DH is not using it.. over time we're going to want to put it back in some form17:33
markmcclainadam_g: since the file is unused atm I'm fine dropping it and adding it back when it's actually used17:33
adam_gmarkmcclain, if its on the roadmap to do something with it lets keep it as a placeholder17:33
adam_gjust to not make it difficult to work in later17:34
markmcclainok it's a feature that some deployers ask about17:34
puranamradam_g,17:43
puranamrin ur latest patch, u have a sleep of 340, will it be possible to add a line comment or so, it will be out of the blue for anyone looking later :)17:44
puranamrin the run_functional.sh file!17:44
adam_gpuranamr, yeah, im not planning on merging that. if it ends up we need to keep it, i'll definitely document it17:45
adam_gi'd like to see if we can slim down the base appliance image in a way that it boots faster17:46
puranamrthanks very much17:46
puranamrhow much does it take typically today17:46
puranamrand where do we want to see it17:46
adam_git takes a few minutes at least currently17:47
adam_gsomewhere between 240-340sec i think17:47
adam_gi wonder if using a single tenant/network/router is okay for our testing purposes17:48
adam_gthen we only have to boot the thing once17:48
puranamras part of my charter (performance) i have the bootup times also included17:51
puranamrwhat does 45 second SLA for Service VM to come up in DreamCompute mean?17:51
markmcclainadam_g: at one point in time I was building an image with buildroot that booted in 7s18:14
markmcclainthe image was ~ 50meg and contained kernel, busybox, python2.7, tcpdump, iproute(2), nftables18:15
markmcclainthe debian base is both a curse and a blessing :)18:16
markmcclainwondering if something snappy like might be a good compromise18:19
markmcclainI do like the updates with rollback side of it18:19
* ryanpetrello is all for deploying on a smaller base image18:34
* ryanpetrello as long as we can add tools to the build we need for debugging when we need to18:34

adam_gmarkmcclain, i wonder if just replacing debian with ubuntu and a modern init system would help?20:13
adam_gsnappy sounds cool but ihaven't looked at it closely enough to know if its ready for use20:13

markmcclainadam_g: possibly.. jessie should be similarly modern with systemd20:49
adam_gright20:50
markmcclainthe biggest bloat is really the minimal install package set which I think is common for debian and ubuntu20:50
adam_gmarkmcclain, re testing and tempest: with multi-tenant testing, do we want the test tenants to use a shared network/subnet/router or to enable isolation and have each test tenant spin up a new router VM?20:51
markmcclainadam_g: ideally I'd like to pass with full isolation20:51
adam_gi imagine for functional akanda testing we can just use a single router VM20:52
markmcclainwe might ahve to hammer on the startup to get there20:52
markmcclainpuranamr: 20GT?20:52
* adam_g tries a jessie build20:53
markmcclainit _might_ work if I wrote the ansible stuff right20:53
puranamrsorry markmcclain, it was referring to T+ switches20:53
puranamrnot the TII20:53
markmcclainpuranamr: I suggested the ly9 since we wouldn't have to mess with QSFP and could recable stuff faster20:54
puranamras agreed earlier, we r in the process of the getting the T3048-LY9 baremetal model20:54
markmcclainalso for whoever wants to take this... low hanging fruit: http://docs.akanda.io/en/latest/operation.html#installation20:55
markmcclainneeds to be updated for kilo/liberty ideally with devstack20:55
puranamrT+ switch (similar to what DH isusing)20:56
