Is /tmp on a physical disk during this part of the installation?  If
so libguestfs can get it.  Something like:

$ echo download /tmp/anaconda.log - |
  guestfish --ro -a /path/to/guest.img -m /dev/device/in/guest |
  grep "switching from media"

However I was also going to suggest something based on virt-dmesg, if
Anaconda sends any message to the kernel message log (if indeed that
is possible).
