On my amd64 machine I am running a riscv64 machine using QEMU 10 with 16 cores. Inside the VM I spin up a further machine with 2 cores. Once KVM emulation is started the load of my amd64 machine rises to > 14/16 cores for qemu-system-riscv64. KVM seems not to release cores that were ever used. Top in 1st VM shows 0.25 cores used for 2nd VM. The usage on my amd64 machine only drops when unloading the kvm module in the first VM. --- ProblemType: Bug ApportVersion: 2.32.0-0ubuntu5 Architecture: riscv64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: zfsdt 2105 F.... wireplumber /dev/snd/seq: zfsdt 2103 F.... pipewire CasperMD5json: { "result": "skip" } CurrentDesktop: XFCE DistroRelease: Ubuntu 25.10 InstallationDate: Installed on 2025-03-17 (80 days ago) InstallationMedia: Ubuntu-Server 25.04 "Plucky Puffin" - Daily riscv64 (20250316) Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet Bus 001 Device 003: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub MachineType: QEMU QEMU Virtual Machine Package: linux (not installed) ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color ProcFB: 0 virtio_gpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.14.0-13-generic root=UUID=af336ba2-ea81-4dd5-bada-b3e8e7fb1c58 ro crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M ProcVersionSignature: Ubuntu 6.14.0-13.13.2-generic 6.14.0 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
