Hyper-V 2022 - VMSS logs constantly about Hyper-V-VmSwitch
Hi guys, any hyper-v gurus around? I have a new 2022 host which will be deployed to production soon. I've found by luck that vmms process (Virtual Machine Management service) constantly logs Verbose messages about "Ioctl Begin ioctlCode: 0xD15" and " Ioctl End ioctlCode: 0xD15, delta (100 ns): 80, ntStatus: 0x80000005(NT=Buffer Overflow)" with Event ID 0 and source Hyper-V-VmSwitch. I've looked around and had no luck finding the cause. It's happening even if I stop all the VMs and I even removed the vSwitch - there is no vSwitch on the host and it still logs like hell. The source is well know SID 1-5-18 (SECURITY_LOCAL_SYSTEM_RID) Anyone saw this before or have any idea what could be the issue here? Thanks for any ideas Martin
