You don’t want kernel panic affecting other users
- cassianoleal 3y agoWhy would your cloud instance panicking affect other users of the cloud provider? Or do you mean something else?
- bionsystem 3y agoAnecdotically, I had the case on VMWare 4 (that was in 2012 or 2013) that a Solaris 11 VM managed to reboot the entire ESX it was hosted on. Very weird bug where ESX passed through some interrupt or something. But in this case I think they mean on the same machine. "In production" would be more accurate than "in a cloud environment". And yeah I wouldn't load custom kernel modules in production just to do observability.
- kqr 3y agoCloud goes beyond rented VMs. Fully managed cloud services have thousands or millions of production customers on the same node. They have to be very careful about what they run as root.
- vocram 3y agoI understand your point, but millions sounds an exaggeration- I have a hard time believing a single node can handle millions of concurrent users
