I am using qemu-kvm right now but I am open to other open source
alternatives!

My assumption that this could be the cause of my issues was based on
this blog post : http://www.parnreiter.at/xorcom-astribank.aspx.

The error messages I got were very close to those mentioned in that
page, especially these ones:

astribank_hexload.c:99: ERROR(load_hexfile): Failed hexfile send start:
-71
astribank_hexload.c:218: ERROR(main): Loading firmware to FPGA failed
'xpp_fxloader'[23554]: /usr/sbin/astribank_hexload failed with status 1 

I am not in front of the server right now and can't test it again, but
from memory I *think* that the error message was the same except from
the value -71 which was more like -73 in my case.

I'll test that as soon as I can!

2.4.1, and I see that dahdi-firmware-nonfree (that includes your
firmware) is 2.2.1.1-1:

That being said, the host (in which the firmware loads fine) has exactly
the same versions installed.

Thanks for your help,
