Hurd tends to hang for me, typically within about 20 minutes of starting it.

I downloaded
http://people.debian.org/~sthibault/hurd-i386/debian-hurd.img.tar.gz as
recommended at http://www.gnu.org/software/hurd/hurd/running/qemu.html
and start using

kvm --curses -net nic,model=rtl8139 -net user,hostfwd=tcp::5555-:22 -hda
debian-hurd-*.img

I then try to install some packages using apt, log into the guest using
ssh, checkout an svn repository, etc. Sooner or later hurd (or qemu-kvm,
I'm new to both) just hangs: No visible change in output and ctrl-c no
longer terminates programs, so I terminate it using killall kvm on the
host. After a few times I usually get an error next time I try to start
Hurd from the same image [see below]

The host is Debian testing 64 bit.

i.e. with the default memory size, which is 128M? That is not much, you
should probably give it more.

Note: these are harmless, and already reported as bogus to e2fsprogs.

Yes (I didn't know about the default). But can this cause the hangs?
I'll try with more memory tomorrow.

Well, most Operating Systems tend to crawl down to hang when they run
out of memory :)

Also, make sure that you don't overflow the filesystem.

I'm updating our documentation to generally run QEMU/KVM with 512 MiB of
RAM.

How can I fibnd out on Hurd?

philipp@debian:~$ df
df: cannot read table of mounted file systems

On the host system all filesystems are at least 50% free.

Hurd has no /etc/mtab. Please do df / :)
