Bug#810862: autopkgtest: vmdebootstrap with setup-commands/setup-testbed fails in Vagrant VM

[Sascha Steinbiss]

Package: autopkgtest
Version: 3.19.1
Severity: normal

Dear Maintainer,

I am trying to set up a testbed for adt-virt-qemu using the approach outlined
in the adt-virt-qemu man page:

$ sudo vmdebootstrap --verbose --serial-console --distribution=sid \
  --customize=/usr/share/autopkgtest/setup-commands/setup-testbed \
  --user=adt/adt --size=10000000000 --grub --image=adt-sid.raw
Creating disk image
Creating partitions
Installing MBR
Creating filesystem ext4
Mounting /dev/mapper/loop0p1 on /tmp/tmpz8dPDu
Debootstrapping sid [amd64]
Give root an empty password
Removing udev persistent cd and net rules
Setting up networking
Running customize script /usr/share/autopkgtest/setup-commands/setup-testbed
EEEK! Something bad happened...
[Errno 13] Permission denied
Cleaning up
ERROR: Permission denied

I am running Debian testing in a Vagrant VM using VirtualBox.
Is there any way to pass through the output from the vmdebootstrap customize
script? In that case I could set -v in setup-testbed to find the offending
line.

Cheers
Sascha
