I've got debian wheezy (7.5) for x86_64 installed on an internal disk
(installed with debootstrap), and a Raspberry Pi running debian wheezy
(7.8) with the x86_64 disk, in an external enclosure, connected to one
of the RPi USB ports. I'm trying to run the x86_64 system in a VM from
the RPi using qemu and chroot, but it dies with a "Segmentation fault"
error:
# chroot /mnt
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
#
I've tried running other programs from the x86_64 disk, sometimes with
success (eg <code>yes</code> works as expected, but <code>bash</bash>
crashes with the same error. I've tried other shells, with the same
result. The configuration files are unchanged from installation in
both host and guest systems; I can send them if required.
I've included keystrokes captured by a "script" session, which
includes details of how I tried to start the VM, and what was mounted
and how, and how much memory (physical and swap) are available, and
the installed versions of relevant software (including bash).
I suspected that the error could be with bash, but other shells fail
with the same error; it doesn't seem to be a memory issue, because the
"free" command says there's still at least 80MB free, and swap hasn't
been used at all.
If you need any more information, please let me know.
