kata-irc-bot<fidencio> @dev.faz, sorry for the late reply.  I don't know, and I there's a high chance this is not exactly tested. Are you tracking this in a GitHub issue?  If not, could you?07:15
kata-irc-bot<fidencio> There are some folks working with us who I'd like to point the issue at their direction, even without the hw to test, they may have some inputs.07:16
kata-irc-bot<fidencio> @christophe, ^07:16
kata-irc-bot<dev.faz> Yeah I will create one. The HW is no issue.. we will provide some.07:16
kata-irc-bot<fidencio> We appreciate the hw offer, trust me, and it'll help a ton with the CI.  But the lack of hw is an issue for an immediate help, as I can't exactly try to reproduce the issue  *now.*07:19

kata-irc-bot<dev.faz> I can give you access to a host with this GPU at any time.07:21
kata-irc-bot<basma.elgaabouri> Hi, I'm trying to install kata using snap https://github.com/kata-containers/kata-containers/blob/main/docs/install/snap-installation-guide.md11:16
kata-irc-bot<basma.elgaabouri> when i reach this `$EDITOR /etc/kata-containers/configuration.toml` I get a permission denied (even with sudo)11:16
kata-irc-bot<fidencio> Hmmm. Can you access that path?11:18
kata-irc-bot<basma.elgaabouri> yes, these are the access rights for the configuration.toml `-rw-r--r-- 1 root root`11:20
kata-irc-bot<basma.elgaabouri> the $EDITOR variable is not set11:21
kata-irc-bot<basma.elgaabouri> now that I set that env var I can edit the file, is there something i should change in the toml file?11:25
kata-irc-bot<basma.elgaabouri> so i followed these steps:11:43

kata-irc-bot<fidencio> Sowrry for the delay13:12
kata-irc-bot<fidencio> Give it a try without modifying.  If the instructions don't explicitly say what should be modified, I'll assume nothing should be modified and then we, most likely, need to update the documentation13:13
kata-irc-bot<christophe> @dev.faz Is the issue with large BAR specific to Kata in any way? I would expect it to show up with qemu as well.13:26
kata-irc-bot<dev.faz> nope.. qemu (kvm) is working without issues13:26
kata-irc-bot<dev.faz> started an kvm instance on the host and was able to forward and use the GPU13:26
*** fuentess has joined #kata-general13:33
kata-irc-bot<christophe> Could you please share the qemu command line in the working and non-working cases?14:51
kata-irc-bot<dev.faz> give me some minutes.. I switched the OS while debugging and have to re-setup libvirt again14:57
kata-irc-bot<dev.faz> just hit submit in the form and got an "my browser did something strange"-err. So have to type everything again :|15:35
kata-irc-bot<christophe> Sorry to hear that, and thanks a lot for the effort ;)15:35
kata-irc-bot<dev.faz> https://github.com/kata-containers/kata-containers/issues/170415:44
kata-irc-bot<dev.faz> so.. finally :slightly_smiling_face:15:44
*** sgarzare has quit IRC15:45
kata-irc-bot<christophe> OK. What I find interesting is your comment that lspci shows the device, and then it goes away. So that reminds me of a trick related to hotplug where we do some ugly resets. David Gibson has been submitting a number of patches to clean that up, but they are not in yet.15:58
kata-irc-bot<christophe> Also, you mentioned to me privately that you followed the instructions here. https://github.com/kata-containers/kata-containers/blob/main/docs/use-cases/Nvidia-GPU-passthrough-and-Kata.md15:58
kata-irc-bot<christophe> OK, so what I see confirms that this si related to the work David Gibson is doing.: ```[    4.328881] pcieport 0000:00:05.0: pciehp: Slot(0): Attention button pressed [    4.328883] pcieport 0000:00:05.0: pciehp: Slot(0): Powering off due to button press```16:00
kata-irc-bot<christophe> Let me bring him in the discussion, but he's in Australia, so we will have to wait. I think we should ask him to connect to the system. How long can you keep the system available?16:00
kata-irc-bot<dev.faz> as long as you want.. as disc. with some other guys our company would be glad to give you access to a V100 dedicated server for your CI/CD16:01
kata-irc-bot<christophe> Super cool. So I will not touch anything for now, I'll wait for David Gibson to take a look. Could you give him access? Let me make the introductions. What email address should I use for you?16:02
kata-irc-bot<dev.faz> you got PM.16:03
kata-irc-bot<christophe> Ack. Expect an email in a few minutes16:03
