@chunfuwen Did this command fail? or jut report error?
I'm using master, which works after the test provider(local files) is set up correctly.

My steps:

1. avocado vt-bootstrap --vt-type libvirt --vt-no-downloads -- reports error but bootstrap pass
2. cd /root/avocado/data/avocado-vt/virttest/test-providers.d/; mkdir downloads, cd downloads
3. ln -s ~/code/tp-libvirt/ io-github-autotest-libvirt
4. avocado vt-bootstrap --vt-type libvirt --vt-no-downloads -- error in step1 will be gone

Could you anyone from your team take a look at this issue?

@chunfuwen @clebergnu ,

1. If we bootstrap for the first time, we got above error in this issue description every time which is also displayed in every avocado-vt pr's cirrus-ci, for example pr 3349 , cirrus-ci job. So I guess this error is as expected. But it will be appreciated if cleber can give more detailed explanation.

2. @clebergnu , according to yingshun's step in avocado vt-bootstrap report error #3346 (comment) which is still used in our libvirt-ci currently. Our purpose is to avoid of tp-libvirt codes being copied from development folder to avocado installation folder. This benefits our debugging and development process. We do not like to modified the tp-libvirt codes in avocado installation folder every time. Could you help confirm if this is recommended usage from avocado side by --vt-no-downloads option?

Yes, that is expected, and it's really a warning. Maybe we can turn the exception name or mechanism, but for now I'd just suggest it to be ignored.

Yes, --vt-no-downloads option is supposed to prevent any download, including any test provider. Then, one would have to set up the test providers (such as tp-libvirt) on their own.

[chunfu] Hi clebergnu,
Quote, "Then, one would have to set up the test providers (such as tp-libvirt) on their own" , what it exactly means specifically?
Since in my local environment, I install all from source, so tp-libvirt is already in my local environment.
