There appears to be an upstream kernel bug report for this issue:
https://bugzilla.kernel.org/show_bug.cgi?id=219210. The patch set
intended to fix it is here:
https://lore.kernel.org/kvm/20240720000138.3027780-1-seanjc@xxxxxxxxxx/.

I will try this out on H100 and see if the issue is resolved.

** Summary changed:

- vmx_posted_interrupts_test of ubuntu_kvm_unit_tests fails with Expected VMX_VMCALL, got VMX_EXTINT on NVIDIA H100
+ vmx_posted_intr_test of ubuntu_kvm_unit_tests fails with Expected VMX_VMCALL, got VMX_EXTINT on NVIDIA H100
