KVM does not work in Ubuntu 24.04 #947

Closed FastestLion9038 closed 2 months ago

FastestLion9038 commented 2 months ago

Running command "kvm-ok" on Orange Pi 5 Plus reports "KVM Acceleration can be used" but trying to do anything related to KVM does not work.

Please provide exact reproducible steps and errors encountered.

I followed this tutorial https://jobcespedes.dev/2023/11/running-virtual-machines-on-orange-pi-5/ and used command:

virt-install -n test --memory 1024 --arch aarch64 --vcpus 1 \ --disk /var/lib/libvirt/images/test.qcow2,device=disk,bus=virtio \ --os-variant=cirros0.5.2 \ --nographic \ --boot loader=/usr/share/AAVMF/AAVMF_CODE.fd,loader.readonly=yes,loader.type=pflash

Using Virt-Manager had some success but it would never boot and it had some issues about the "Relaxed State" for the cpu XML configuration.

I also used https://github.com/dockur/windows-arm/ but it failed at the point when it would try to boot the Windows VM due to KVM issues.

Running Command "kvm-ok" says KVM can be used but in reality, any VM using KVM will not boot. Only pure QEMU VM's will actually boot.

Update

Turned out to be a user permission problem for accessing /dev/kvm. Adding myself to the kvm group fixed things slightly. Now I have an error reporting: "kvm: Cannot enable KVM when guest CPU has EL3 enabled"

Nevermind, Fixed all my issues by using virt-manager directly after adding myself to the /dev/kvm group. Got past that EL3 error by using virt-manager instead of command line to start the VM.

Thanks @Joshua-Riek
