Hyper-V VM randomly drops connection and does not reconnect

Sartharon commented 2 years ago

Host

OS: Windows Server 2019 July CU 2022 installed (10.0.17763 Build 17763)
CPU(s): Dual Socket Xeon 2620v4 (thus needing some parts of Haswell(-E) specific configuration. I.e. CPU-Emulation and some others, as provided here)
SRV-IO is enabled in BIOS
Virtual Switch has a dedicated 10G NIC (Intel X540-T2) with SRV-IO enbled

Kexts

Lilu: 1.6.1
MacHyperVSupport: 0.9 (Followed Hyper-V specific configuration mentioned here)
OpenCore: 0.8.2
VirtualSMC: 1.3.0

macOS

Version: Big Sur (Online Installer)
Recovery download source: macrecovery.py from OpenCore Utilites

Other

IPv6 Router Advertisements are enabled on my Network
Other VMs (non macOS) do not experience this network dropout

Issue Description

The recovery boots without any issues and at first an internet is present. ifconfig shows: pinging google works fine as well:

After some time, the connection just drops and will not connect. Thus, the installer cannot finish downloading and the error message "PKDownloadError error 8" is shown. Thus, installing macOS is not possible. Ping just receives timeouts after the connection has dropped, even to the router. My Router then also shows the device as shutdown/not connected. The setuplog shows the following after a while:

Retrying http://swcdn.apple.com/content/downloads/44/35/012-22320-A_AOID136T4U/[......]
Started downloading package com.apple.pkg.InstallAssistant.macOSBigSur (http://swcdn.apple.come/content/[....])

If you need anything else (probably Debug logs from the HyperV.kext) let me know. Not sure how to enable and/or save/access hyperV.kext debug logs. Though I use the debug version for now and enabled as much debug stuff as mentioned in the OpenCore documentation.

Edit: Disabling IPv6 on the Network does not help either

Does this occur with SR-IOV disabled on the vSwitch as well? Having it enabled/disabled in either case shouldn't matter as macOS just doesn't have the support, but would like to rule that out. For drop out time is it consistent after a certain about of time/data and how long?

Sartharon commented 2 years ago

I've created a new External Switch without SR-IOV and gave it a different 10 NIC which is not used by anything else. Assigned that switch only to the Hackintosh. So no difference there, just as you expected.

For drop out time is it consistent after a certain about of time/data

No not really it's somewhere between 5 and 35 minutes, and then I can see that the installer starts retrying the download and I can see in on my router that no traffic is generated by the VM/macOS anymore.

and how long?

Indefinitely, but then again I cannot retry the installation most of the time since the OS just locks up retrying the installation after pressing "Ok" on the "PKDownloadError error 8" message, being thrown back to the main recovery screen and choosing to install the OS (again). I can open the Terminal at that time, though. Even using nslookup or pinging an IP after 20 minutes shows that macOS doesn't have an internet connection, nor does my router show that it's even connected anymore

Not sure if this is indicating something, but the first download retry happens shortly after a router advertisement (IPv6) but then again the issue is present even when disabling IPv6 and therefore not having any RAs.

I might as well give you access to the VM and its VHDXs if you need that.

@Sartharon Not an answer, but how exactly did you set up the hyper-v VM? I have been trying but I can not do it.

Since this is very much OT I'll keep it short:

Create a VHD of 16GB attach it on any Windows Machine
Format it as FAT32
Follow the OC Install Guide for a bit
Make sure you use the correct SSDTs and Quirks as provided here
Create a 2nd VHD for macOS itself
Unattach the VHD on the Windows Machine
Create a VM for macOS without Secure boot attach both VHDs and make sure you boot from the smaller VHDs
Boot the VM

I can't get an internet connection at all.

Could anyone at least boot macOS with a Ryzen CPU? I'm unable to get past the kernel hand-off, and I don't know if this is an AMD issue (Ryzen 5 3600)

@ivansavra1 i cant even boot with ssdt-hv-dev

I don't understand why there isn't a proper guide from Acidanthera or Dortania, this has a lot of potential, running macOS on Hyper-V is probably the best way: You get the performance and the flexibility of running games on Windows without performance impact.

Did a test myself and cant boot with the new hv-dev either anymore neither Montery nor BigSur (with the correct kext ofc) A Kernel Dump during the initialization referencing the asml is generated.

But that is a different issue than the one this topic is about

@Goldfish64 I see you're active on this project, can you make this happen? This project deserves more use, it would be awesome if there was a section on Dortania or at least on the Github README.

Did you ever got stuck on EXITBS:START? I can't get past this, I tried hackintosh on Hyper-V last year and I also couldn't get past this no matter what, I don't know what to do, I'm already using the AMD patches.

I randomly get this error on boot and connection doesn't not work at all.

Goldfish64 commented 2 years ago

@Sartharon Can you test with the latest commits of the kext? After much troubleshooting believe the random stall issues have been resolved for networking and storage. Regarding the SSDTs the ones in the OpenCorePkg releases should be fine on 10.8 and newer, but may need to be built with an older iasl version for older macOS versions.

Sure, could you please provide a kext with those commits? 0.9.1 was built before the network changes.

I've been using version 20210604 from acpica for Windows. Do you want me to switch to an even older version?

Can you upload the panic/dump that is printed when using the SSDTs?

Thank you!

Nvm the PLUG aml was loaded before the DEV aml (Probably because of the snapshot I've taken after replacing the aml). So no more panic / dump.

Though not sure what changed, either the new OpenCore version or the hyperV.kext, but I cannot get into the installer anymore. During booting, it just gets stuck on this (maybe you might have an idea since that recovery booted just fine before. Seems like a RO problem to me which is weird):

Edit: Redownloaded the recovery image and get stuck on this now: and sometimes on this:

Closing this

Since the Boot freezes were caused by UIScale being 0 instead of -1 and SecureBootModel being Default instead of Disabled

Can you provide an example config.plist that is working for you?

Also, did you make any changes to the sample.plist besides the changes mentioned on the MacHyperVSupport instructions?
