In a comment to PR 47157, I said:
Issue 5: After manually starting xencommons and xend (in that order),
I tried installing a NetBSD 5.2 domU and running the ATF tests using
anita --vmm xen test http://ftp.netbsd.org/pub/NetBSD/NetBSD-5.2/amd64/
This ended in a domU kernel panic while running the fs/tmpfs/t_rename
test. This is reproducible, and also happens with a 5.1 domU, though
the exact test where the panic happens varies; so far, it has happened
in fs/tmpfs/t_rename, fs/tmpfs/t_remove, and fs/tmpfs/t_link. A 6.0.1
domU is not affected by this.
Since PR 47157 was focused on documentation issues and has now been closed,
I am opening a separate PR to track the NetBSD 5 panic issue.
Running the following shell script will reproduce the bug by doing an
automated install of NetBSD/amd64 6.1.5 with Xen 4.2 in a qemu virtual
machine, installing a NetBSD 5.2.3 domU, and running the ATF tests in
Anita version 1.37 (in pkgsrc-current as misc/py-anita) is recommended
since some earlier versions can't reliably run a recursive invocation
of anita in the VM. You also need about 5 GB of disk space.
Before blaming qemu, please note that qemu was not involved in the
original panics reported in PR 47157.
