I'm running Debian Stretch and I downloaded and extracted the latest posbox image from https://nightly.odoo.com/master/posbox/, installed qemu and executed:
/usr/bin/qemu-system-x86_64 -machine accel=kvm -m 1024 -drive file=/path/to/posboxv15.img,media=disk,format=raw,index=0
A QEMU window pops up and it hangs indefinitely on "Booting from Hard Disk...". The process has high CPU usage.
Here's a screenshot: http://i.imgur.com/kpo5KKB.png
Did I do something wrong here?
I also tried adding the "bootable flag to each of the partitions in the image (one at a time), but that had no effect. I tried to edit the question and add this, but I get a 403 error.
