Let's see what the problem is. + +The bug report mentions "hv-tlbflush malfunctions on Intel host CPUs with neither EPT nor VPID." So, it's related to KVM and hypercalls because hv-tlbflush is a hypercall used in KVM for TLB flush operations. The issue arises when the host CPU doesn't support EPT (Extended Page Tables) or VPID (Virtual Processor ID), which are features that Intel CPUs might have. + +The problem occurs on older Intel CPUs that support VT-x but lack EPT and VPID. Enabling hv-tlbflush causes bluescreens in the guest OS because KVM doesn't handle this scenario properly. It seems like KVM is not checking for both EPT and VPID availability before attempting to use hv-tlbflush, leading to issues when neither is present. + +Looking at the possible categories: Mistranslation, Assembly Lowering, Other, Device, Graphic, Socket, Network, KVM, Boot, VNC, Debug, Files, Permissions, Performance, Kernel, Peripherals, Hypervisor. + +Since this issue is directly related to how KVM handles hypercalls and TLB flush operations on Intel CPUs without certain virtualization extensions, it falls under the hypervisor category. The problem is within the hypervisor's handling of specific CPU features during VM operations. +</think> + +KVM \ No newline at end of file |
