Ok, so it is probably a good idea to explicitly request a dispatch after
activating virtio-rng, so we do not depend on this happening by pure
luck for other reasons:
--- a/OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c
+++ b/OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c
@@ -670,6 +670,7 @@ ConnectVirtioPciRng (
if (EFI_ERROR (Status)) {
goto Error;
}
+ gDS->Dispatch ();
}
return EFI_SUCCESS;
[ untested patch, and we probably should do something similar for ArmVirt,
/me goes continue walking through my email backlog now ]
take care,
Gerd
