I fail to come up with a use-case that just wants to add CPU/RAM without onlining it sooner or later. For virtual environments, you add CPU/RAM to use it and therefore want to online it once it appears. In a cloud environment (like ProfitBricks), it makes no sense to add CPU/RAM without using it, because you have to pay for it.
Hot-add is supposed to work on recent kernels (>= 3.10). Kernel 3.2 had an issue, but I can't remember if adding CPU/RAM or onlining it causes the issue. I would be happy to unconditionally turning hot-add on and SRU the udev rule back to Ubuntu 14.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1233466/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
