bug: the windows-11.conf does not get properly populated by quickget windows 11

[iopq]

I confirm this bug has not already been reported

• I have searched the issues and this bug has not been reported previously

Describe the bug
When I run quickemu --vm windows-11.conf I get

qemu-system-x86_64: -drive media=cdrom,index=0,file=windows-11/windows-11.iso: Could not open 'windows-11/windows-11.iso': No such file or directory

in fact the quickget windows 11 command doesn't actually download a thing called windows-11.iso, it gets the following files:

disk.qcow2  OVMF_VARS.fd  unattended  unattended.iso  virtio-win.iso  Win11_24H2_EnglishInternational_x64.iso  windows-11.log  windows-11-monitor.socket  windows-11.ports  windows-11.sh

To Reproduce
Steps to reproduce the behaviour:

1. quickget windows 11
2. quickemu --vm windows-11.conf
3. see the error

Expected behaviour
it should just run the correct .iso file

Quickemu output
Run quickemu or quickemu and include the output of the failure below:

Quickget successfully downloaded the windows ISO, as opposed to you downloading it yourself after a failure, correct?

Quickget successfully downloaded the windows ISO, as opposed to you downloading it yourself after a failure, correct?

Yes, but as opposed to the Windows 10 script, it didn't correctly start it after just the two lines I typed

[lj3954]

Are you completely sure the ISO successfully and fully downloaded, as opposed to throwing an error and prompting you to download it yourself? Does pointing the config file to the correct path allow the VM to boot correctly?

Looking at the code, I don't believe it shouldn't be possible for this issue to occur.

I have the .iso downloaded just fine, it did complete. I do run into a separate issue later when installing, though:

#1475

but this isn't related to the issue at hand since the iso actually booted into the installer after I changed the .conf file

The only thing I can think of is I restarted the installer a few times because the virt drivers were taking hours to download and they finally finished when I downloaded through a proxy

[lj3954]

That would probably do it. You restarted the download enough times for Microsoft to ratelimit you while getting the URL for the Windows ISO, making quickget skip the step and set the ISO filename to a default value. That's not going to be an issue that we can fix.

The .iso is already downloaded and the file is 100% complete, it seems you should be able to skip that step once you already get an iso

[lj3954]

Quickget has a --create-config flag that can be used with existing ISOs. Otherwise, it will always get a URL, expecting to require a download. The only way it will determine you already have the correct ISO already downloaded is if it (curl) has a filename & size to check for, which would require getting a URL.
