Naming this derivative kernel "kvm" was not the best idea in hindsight. It was done to achieve fast booting guest images. Towards that goal everything was streamlined and part of that is keeping per-cpu structures smaller by limiting the number of CPUs.
The generic kernel (which should be installed via the linux-generic meta-package) can run as a VM guest but for that has the downside of pulling in some bigger dependent packages (linux-firmware, crda, linux- modules-extra, ...). To avoid that there is the linux-virtual meta- package which will only pull in the kernel and a sub-set of kernel modules (without linux-modules-extra) and the other dependencies. That reduces its on-disk footprint. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967131 Title: CONFIG_NR_CPUS=64 in -kvm is too low compared to -generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-kvm/+bug/1967131/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
