@kotlarmilos there is a failure on #112547 indicating that for CoreCLR on Android we use a queue which has only x86 emulators, causing the test to fail as we target x64 specifically.

Do we have queues with x64 emulators only that we could use?

[kotlarmilos]

I am not aware of a separate queue with x64-only emulators. This failure appears to be machine-specific. In successful runs, there are two emulators available, and one is selected. I assume one is x64 and the other is x86. Here is an example of a successful run: https://helixr1107v0xdcypoyl9e7f.blob.core.windows.net/dotnet-runtime-refs-pull-112625-merge-5c5e4bed3d564f6eb6/Android.Device_Emulator.JIT.Test.Attempt.2/1/console.7eba4a2f.log?helixlogtype=result

Alternatively, we could restart this specific machine.

I think queues with Android API <= 29 have both x64 and x86 simulators installed and it appears that XHarness is trying to connect to both even though we need just the x64 version. I think re-run would make the test pass.

Alternatively, we could restart this specific machine.

I think these are VMs but you can try asking in First Responders as it seems that this specific VM is on the top of the failures list (in the past 3 days).

Yes, I think that is the problem, or better to say that on this particular failure there aren't two emulators installed:

[21:40:21] fail: No attached device supports one of required architectures x86_64

Via xharness we:

• first fetch available devices via:
  adb devices -l
• Then for each of them we check the supported architectures:
  adb -s <device-name> shell getprop ro.product.cpu.abilist
• If we find the match, we pick that emulator.
• If we don't find the match, we throw:
  https://github.com/dotnet/xharness/blob/32f83a8881e5142504a9089bac4aa98382a08f75/src/Microsoft.DotNet.XHarness.Android/AdbRunner.cs#L769

I think this host machine just does not have a x64 emulator installed and that is why it fails. The question is, if it is the only host with this problem.

[steveisok]

@ivanpovazan did anyone raise this with FR? They should be able to go into the machines and determine if it's all installed properly.

[ivanpovazan]

I updated the ErrorMessage pattern to: fail: No attached device supports one of required architectures x86_64 as the previous one was picking up cases when there are no devices at all.

[ivanpovazan]

The problematic machines have been deleted. I suggest monitoring this issue for some time, to see if we catch some other misbehaviors.
