I noticed it in the gitlab-CI, the test was hanging and got marked as 
"INTERRUPTED":

 https://gitlab.com/thuth/qemu/-/jobs/3922243532#L214

As far as I could see, this was the only new failure there. There is another 
one in the avocado-system-fedora job here:

 https://gitlab.com/thuth/qemu/-/jobs/3920337136#L307

... but I think that was pre-existing and was caused by one of Philippe's 
reworks, hopefully to be fixed soon ... Phillipe?
