Normally, you're in the HV console after you input command "vmexit", you can still input other commands.
On MRB it work well, just checked.

I am talking about the 'vmexit' command you can use from the hypervisor console (it's listed here: https://projectacrn.github.io/latest/user-guides/acrn-shell.html). When I used it, it printed out a lot of info but I couldn't figure out how to get back the console prompt (so I could issue new/different commands).

I think you're talking different things.

Vmexit command in "hypervisor console" is used to show the info/count
which cause vmexit; it is used for debug.
Not sure if it is included in our doc.

After the command "vmexit", you're still in hv console

That depends on how you trigger vm-exit.

Basically, VMM needs to advance the GIP to mark the end of execution
of the guest instruction.

Thx Eddie

Hi folks,

I called 'vmexit' from the hypervisor console, that displayed a
bunch of info on the screen... but I don't know how to return to the
console (and I couldn't find that in the online doc). What's the trick?

Thanks,
Geoffroy
