kata-irc-bot<peter.ranson> Hey gang. We are in need of running a 32-bit application in a kata container. I understand that the normal VM image does not support 32-bit applications and we would need to build one from scratch. We did attempt this a few years ago, but did not manage to succeed as its a bit out of our comfort zone.  I appreciate that you do not have commercial support, but we are willing to pay to get this image created. This could be a09:45
kata-irc-botdonation to the project, or an agreement directly with someone who can do this.  We would also be willing to provide a case study on our final setup. To give you some context, if this works as we hope, then we will be running over 10,000 containers on a kubernetes cluster spanning over 1,000 physical hosts.  Is this of any interest?09:45
kata-irc-bot<jakob.naucke> I don't think I could take this up due to my employment, nor do I want to kill anyone's bounty here, but allow me a "stupid" question: Can't you just (assuming x86 & Debian-based) install `libc6-i686` and be done with it?10:02
kata-irc-bot<peter.ranson> Things may have changed in recent versions. But issue we had was that the kernel had 32-bit support disabled. It was impossible to run anything 32-bit. The applicaiton its self is wine, which in turn runs a 32-bit 3rd party app. We tried at the time to run a simple 32-bit c app, that also failed.  Not sure if we tried libc6-i686 but we were going back and forth for a bit on a github issue about this.10:05
kata-irc-bot<fidencio> @peter.ranson, this should be a matter of enabling `CONFIG_IA32_EMULATION` on the kernel image and you should be good to go, following Jakob's suggestion.10:24
kata-irc-bot<jakob.naucke> in case there are more missing libraries, check a multilib-enabled `ldd` and see what's missing10:30

kata-irc-bot<fidencio> Speaking on behalf of the community here, we'd be interested to know what are the use-cases your company has for Kata Containers, to have your company working closer to the project, and also to understand the limitations you've hit, and how to unblock that.10:40
kata-irc-bot<peter.ranson> thanks for the image, we will give this a go tomorrow and update13:26
kata-irc-bot<itskumaresan> Team, can someone help here to understand. The scripts attached 22:17
