Public bug reported: Using the official Ubuntu 19.10 arm64 image, http://cdimage.ubuntu.com/ubuntu/releases/19.10/release/ubuntu-19.10 -preinstalled-server-arm64+raspi3.img.xz, with the 5.3.x Linux kernel has KVM/VIRTUALIZATION disabled by default and therefore /dev/kvm acceleration is not available on installations on newer Raspberry Pi 4 (for example) which has a supported processor (armv8) by KVM (https://www.linux-kvm.org/page/Processor_support#ARM:).
I'm able to compile the kernel manually with the options enabled in the kernel config (http://dl.rohityadav.cloud/cloudstack-rpi/kernel-19.10/) and further verify that it works well in deploying ARM64 VMs (http://dl.rohityadav.cloud/cloudstack-rpi/template/). I went a bit further to deploy an Apache CloudStack based IaaS deployment and verify that it works as well. Having KVM enabled arm64 devices would enable testing and misc use-cases on newer boards such as the Raspberry Pi 4 (4 GB RAM). Can the Ubuntu kernel team advise why KVM is not enabled in the kernel by default, and if this will change in future? Thanks. ** Affects: linux-raspi2 (Ubuntu) Importance: Undecided Status: New ** Tags: arm64 kernel kvm pi raspberry ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849369 Title: Ubuntu 19.10 ARM64 kernel has KVM disabled by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1849369/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
