Thanks for this feedback and sorry to hear about this issue.

As far as I know (Sergio will correct me if I'm wrong :) there is a
new version of ubuntu-device-flash almost ready that avoids using
qemu-arm and uses a new feature in snappy-go instead that allows
setting alternative root dirs for working with snaps.

Hope this will fix your issue.

Cheers,
 Michael
