My setup runs nixos as an hyper-v guest, and I’m having issues with running any type L2 guest. This is especially annoying for nixosTest instances.
[ Hardware: Physical CPU (VT-x) ]
│
[ L0 Host: Windows 11 + Hyper-V ]
│
[ L1 Guest VM: NixOS (Hyper-V VM) ]
│
[ L2 Guest VMs: nixosTest framework (QEMU using /dev/kvm) ]
On my computer the L2 guest hangs during boot.
I’m starting to feel like this setup is not supposed to “just work”. And this is going into territory way above my head. It looks like a (spin)lock where the vCPU just doesn’t advance, no errors or warnings thrown by the L2 guest kernel. Hopefully someone more experienced knows what is going on here 
I took a trace from L1 during L2 boot, which is summarized by claude like this;
The ftrace capture at the hang point showed ~150,000 vmexits/sec sustained with only 1 HLT across 401,042 events — a genuine livelock (continuous execution that never completes), not a stuck or deadlocked vCPU.
Exit reasons were dominated by IO_INSTRUCTION (87,599, mostly serial-console LSR/THR polling and PCI config-space access) and EPT_VIOLATION+EPT_MISCONFIG (64,880 combined), while MSR_READ/MSR_WRITE were negligible (103/57) — meaning the guest's local APIC was still in legacy xAPIC (memory-mapped) mode, so every LAPIC touch (EOI, IPI, TPR) trapped through the unaccelerated MMIO/EPT path rather than a cheap MSR trap.
That EPT/MMIO-trap dominance directly corroborates this host's flexpriority=N/enable_apicv=N (confirmed via kvm_intel module parameters and /proc/cpuinfo's vmx flags) — Hyper-V's nested-VMX exposure omits the whole APICv/TPR-shadow secondary-control group, forcing every interrupt-related APIC access into software emulation.
