Bug#892023: autopkgtest-virt-qemu: Fails creating test environment sometimes
Package: autopkgtest
Version: 5.1
Severity: important
Dear Maintainer,
Because I need some VM level separation, I have to use qemu for testing my package.
Unfortunately, when I run my tests (there are a fair amount of them), most of the
time one test fails with a virtual host creation issue. As far as I can tell it
usually fails at the same test case but I think this is happen because the bug
is depending on the number of the created virtual host not because of the test case
itself. Especially because I run the same test script just on different package
set.
Previously, when I was running the test with debug it has more chance to success, but
not any more.
By the way, the package, I try to use autpktest with is syslog-ng. The command I run is:
autopkgtest --debug syslog-ng_3.13.2-4~1.gbpa514e1_amd64.changes -- qemu /var/cache/autopkgtest/autopkgtest-sid.img
And the error message I receive is the following:
autopkgtest [09:35:09]: test basic: - - - - - - - - - - results - - - - - - - - - -
basic PASS
autopkgtest: DBG: sending command to testbed: copyup /tmp/autopkgtest.a1psrU/basic-artifacts/ /tmp/autopkgtest.output.k7snm27u/artifacts/

Last time I felt enough debug-fu in myself I discovered that when this happens, the
serial console is unaccessible. Unfortunately I know barely anything about qemu I just
get to know how it can be used. But if somebody points me in the right direction I
can do more tests.
By the way, I just run the test to check how long it need to show the error message, but
now it passed.
