    High VM-EXIT and Host CPU usage on idle with Windows Server 2025

    High VM-EXIT and Host CPU usage on idle with Windows Server 2025

    No, it's off. 24H2 indeed introduced per core clock ticks, and apparently that is what kills residency in VMs. I don't really understand why, but that is one difference in the KiSetTime/KiGetTime functions in 24H2 compared to Server 2022, for example. Fortunately, this is gated behind a kernel...

    High VM-EXIT and Host CPU usage on idle with Windows Server 2025

    Something's wrong with this OS. You can bump that number in the Python script, I tested with 500ms. The pkg pc6 residency then reaches 60-70% when idle, as was the case with previous versions. Effects can be easily seen, for example, the cursor takes a moment to move after it's been stationary...

    High VM-EXIT and Host CPU usage on idle with Windows Server 2025

    For completeness, here is also my full virsh XML for this VM: <domain type='kvm' id='2' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>console</name> <uuid>837730e7-258a-4357-865b-375fe422825f</uuid> <memory unit='KiB'>33554432</memory> <currentMemory...

    High VM-EXIT and Host CPU usage on idle with Windows Server 2025

    Hi guys, I spent a quite some time trying everything mentioned here and in other threads related to this. For me, the benchmark was being able to lower PkgWatt and reach Pkg%pc2 and Pkg%pc6 residency in my VM. This VM I run on my laptop (ThinkPad P1 Gen 8, i7 265H, 64GB RAM, no NVIDIA GPU) onto...

    Windows 11 hangs with 100% CPU usage

    I need Hyper-V for the workloads that I run. I also don’t know where to look, dmesg doesn’t show anything interesting when the VM locks up. I don’t even know what’s to blame, that’s the thing…

    Windows 11 hangs with 100% CPU usage

    Yeah, indeed, I think I have a consumer X570-based Asrock motherboard, if I remember correctly (the system is at a remote site, and it’s the holidays, don’t fancy going there at this exact moment) and it is very crap indeed. Fan control is stupid, it’s either low RPM, or as soon as the CPU is...

    Windows 11 hangs with 100% CPU usage

    I experience the same. Ryzen 9 5900X. Windows 11 VM on Proxmox 7.1.2 and kernel 5.15. 5.13 was unusable for me, the NVIDIA Quadro GPU was not being passthrough correctly, giving the famous code 43 in Windows. This platform is doomed. I have bought this CPU way back in the summer and have not...
