Package: qemubuilder
Version: 0.73
Severity: grave
Justification: renders package unusable


Hi!

I'm trying to use qemubootstrap in Debian testing, but it hangs after
extracting the packages and doing some filesystem work, apparently before
running qemu/kvm.

I'm using simple command lines, and reproduced this in two different systems
with different kernels (one using Debian's kernel, the other hand-built),
where I've verified that kvm works just fine. Because of that, I've put this
as "grave" severity, but please let me know if it's not appropriate.


Here's the summary of the output:

[here it hangs]


If I do a "ps auxf" at this point, I see:

An strace shows it seems to be trying to read from a file descriptor, which
upon inspection in /proc and lsof, it's an unix socket.

If there's anything else you need to know or want me to try, please let me
know.

Thanks!
