kukaczhi, I'm searching for a reliable automated method to identify the operating system type within a running instance, without having access into it. has someone solved such task perhaps already?14:01
smcginnisThat's a security issue kukacz. Most hypervisors go to some lengths to make sure instances are not able to find out anything about the host they are running on.14:06
kukaczsmcginnis: actually I'm searching for the reverse task - look from hypervisor what's inside the guest14:09
smcginnisAh14:09
kukaczand I can't rely on qemu guest agent or anything like that14:09
kukaczfirst we believed we could get the info by fingerprinting console logs, then we noticed those are emptied during live migrations, which we do quite often14:10
smcginnisNothing that I know of to get that reliably, but maybe someone else here might have some ideas.14:10
kukaczsmcginnis: thanks anyway!14:12
kukaczlast I've been trying to read the partition type info from root disks - I'm facing issues with RBD (Ceph) volumes device mapping though. maybe someone got experience with this ...14:16

mattiakukacz, what do you need to know? if it's linux or windows or also version/distro?14:54
kukaczmattia: linux or windows will help too. version/distro would be the best, of course14:56
mattiaa silly method like connecting to the console has been alredy been ruled out?15:03
kukaczmattia: yes, that's tough to parse and mainly the console log is empty (or missing) after an instance is live-migrated to different compute node15:07
mattiaI did not mean the log, though15:08
mattiaI actually meant connecting and getting a tty or what windows give you15:09
mattiabut yes, the windows case would not be parsable15:10
mattialinux would however with the usual <DISTRO> login: text15:10
mattiaI don't know if it's still a thing but you could enable the serial-console on nova (have no idea about the security implications but depending on your usecase it could be acceptable)15:21
*** jamesmcarthur has quit IRC15:30
*** simon-AS5591 has quit IRC15:31
kukaczmattia: thank you! seems that I've fixed the issue with RBD image mapping, so I'll probably stick with the partition type check method applied on root disks15:31

mriedemsorrison: mnaser: dansmith: i think this was mentioned last week, but a policy rule is probably preferable for enabling cross-cell resize than just a boolean config option right? so you could have control over who can do it, so maybe you only want admins doing it at first to make sure it's cool before you turn it on for non-admins doing resize.20:51
dansmithyup20:52
mnasermriedem: i think that seems like a good approach20:52
mnaserreminds me of that bfv with root_gb=0 patches20:52
mnaseri think we mentioned stein default was gonna be to disallow it?20:53
mriedemmnaser: yeah, ...need to update that20:56
mnasermriedem: pushing up a patch20:57
mriedemthere is a ton of stuff we can probably change/drop in stein at this point for "todo: do this in queens"20:57
mriedemmnaser: just ping me when you get that pushed20:59
mriedemremember to push it real good20:59
mriedemwhich now that i know how old you are, you probably don't get that reference20:59
mnasermriedem: hey now i know a reference or two21:02
