O-NET | Joint Face Detection and Alignment using Multi | Machine Learning library

A QEMU image running the 'user-mode' networking (as in your command line example) already has access to the host machine. It can access it either via any (non-loopback) IP address the host has, or by using the special 'gateway' IP address. If you're using the default 10.0.2.0/24 network setting then the 'gateway' is 10.0.2.2. I haven't confirmed but suspect that for a non-default net setting it will still be on .2, so in this example 192.168.76.2.

You cannot literally make 'localhost' in the guest point to the host PC, because 'localhost' for the guest is the guest itself, and having it point somewhere else would likely confuse software running in the guest.

The hostfwd option is for forwarding connections from the outside world to a server which is running on the guest. "hostfwd=tcp::HOSTPORT-:GUESTPORT" says "QEMU should listen on the host on port HOSTPORT; whenever a connection arrives there, it should forward it to the guest's port GUESTPORT (which hopefully has a server listening there)".

You seem to be running a server on the host. You can't have more than one thing listening on a particular port on one machine, so either the python3 server program can listen on port 28009 and respond to connections there, or QEMU can listen on port 28009 to respond to connections there (forwarding them to the guest), but not both at once. Whichever is started second will complain that something's already using the port.

If you want to run a server on the host and connect to it from the guest, you don't need any QEMU options at all. QEMU's 'usermode' networking will allow guest programs to make connections outwards to any IP address (including the wider internet but also directly to the host), so if you are trying to run a client on the guest and a server on the host that should just work. You can tell the guest client to connect either to the host's real IP address or you can use the special 'gateway' IP address 10.0.2.2 which is how the host machine appears on the fake network that the guest sees.

Not knowing what process you have followed so far, I found two resources that may be helpful here for you..

This comment from yu3fms on a GitHub repo about QEMU on M1 discusses using brew for ARM and specific patches for QEMU to enable vhf acceleration.

And this Syonyk's Project Blog post, The Apple M1, ARM/x86 Linux Virtualization, and BOINC is a great tutorial on how to get QEMU up and running on an M1 Mac for both ARM and x86 guests.

Create the classes and try this code:

In fact, you do not have to complicate this issue too much. The truth is that net standard 2.1 does not support net core 2.1.

See this document.

Net Standard 2.1 supports at least Net Core 3.0.

You only need to change your main project targetframeworks to netcoreapp3.1;net48 or change targetframeworks of your lib project to netstandard2.0;net48 and the warning will disappear.

I had the same problem. You need to have an ASP.NET runtime.

It's a bit confusing and easily overlooked, but it says you need an Microsoft.AspNetCore.App runtime, and dotnet --list-runtimes only lists Microsoft.NETCore.Apps.

The ArchWiki mentions:

This is caused because the runtime is shipped as a separate package in Arch. You just need to make sure you have the aspnet-runtime package installed as well.

To install the .NET 5 runtime:

I found an answer here.

The point is that i have centos-7 minimal that requires some network settings being up manually. For the workaround i needed just run dhclient manually:

These auth ways apply to different scenarios, for example, if you want to use Active Directory Integrated authentication, you need to federate the on-premises AD with Azure AD via ADFS, if you want to use Active Directory Managed Identity authentication, you must run your code in an Azure service which supports MSI(need to enable MSI first), because the code essentially makes an API call to the azure instance metadata endpoint to get the access token, then use the token to auth, it is just available in the MSI-supported service.

So if you want to migrate the code from the old sdk to the new one, you need to choose the correct auth way that applies to your scenario. Here I recommend you to use the Active Directory Service Principal authentication, it can apply to any scenario, please follow the steps below.

1.Register an application with Azure AD and create a service principal.

2.Get values for signing in and create a new application secret.

3.Grant the permission to the service principal with CREATE USER [Azure_AD_Object] FROM EXTERNAL PROVIDER.

4.Then use the code here, fix the values with yours and got from step 2.

I later submitted another question with more details, and with an "answer." You can check that out here
