Bug#851429: installation-reports: mounting CD fails on qemu-system-aarch64

[Adam Borowski <kilobyte@angband.pl>]

Package: installation-reports
Severity: normal

Hi!
I'm afraid that regular arm64 d-i images fail to detect qemu's CD-ROM, and
there's apparently no way to direct it to load udebs from a network mirror
like mini.iso does.  On the other hand, installation with mini.iso works
well.

The failing step is "Detecting hardware to find CD-ROM drives".

CD=debian-stretch-DI-rc1-arm64-netinst.iso
NET="-net bridge -net nic"
