bug: non-zero return value

[sgon00]

I am not really using quickemu and just trying it. I am trying to run a simplest linux. The VM can be ran successfully, but the command returns 1 with error instead of 0. I have no ideas what's going on because there is no erorr message at all.

Expected behaviour

quickemu --vm alpine-3.15.conf returns 0 to indicate the command is returned successfully OR if it fails, it should print out proper error message to tell user what the error is.

Actual behaviour

quickemu --vm alpine-3.15.conf returns 1 instead. It means the command failed to execute, but the guest OS is actually working.

Steps to reproduce the behaviour

quickemu --vm alpine-3.15.conf

How strange.

Everywhere in quickemu where exit 1 is called has a clear error message preceding it. So, I do not think it is quickemu setting the return value to 1, but qemu itself. However, I do not know what would be causing qemu to successfully start the VM yet return an exit status of 1.

@flexiondotorg thanks a lot for the reply. I am not sure how to debug qemu. I can see the popup screen shows the text Guest has not initialized the display (yet). for 1 second, then the OS starts. I am not sure if the error has anything to do with this message or not. Just FYI.

Some unrelated backgrounds: I am not really using quickemu, so I haven't paid too much attention on this issue. I tried to install MacOS with quickemu, but failed. That's why I installed quickemu at the beginning.

I have the same result. The VM still seems to start fine, and debugging show that the script execute up to the end (if it say something like ' - Process: Starting kolibrios-latest.conf as kolibrios-latest (56960)', it means it ran up to the end of setting up the VM. The next part is starting the viewer if necessary, which run with no problem too, and the script run up to the end (and KolibriOS indeed seems to work fine).

On the NixOS package in case that’s relevant

I am also having this issue. The vm starts fine but then quickemu stops with a exit code of 1
