Import locally defined hosts into Windows VM hosts file
#!/bin/sh
# hosts-to-vm.sh
#
# Made for use alongside the excellent ievms -
# https://github.com/xdissent/ievms
#
# Will export the local hosts (from /etc/hosts)
# to a batch script & add that batch script to a Windows VM
# The batch script will be executed to import the hosts onto the VM
# The batch file seems convoluted, until you only want to append the new hosts.
#
# REQUIREMENTS :
# VirtualBox & Guest Additions installed (v4.0 or greater) on the guest
# VirtualBox command line tools installed on the host
# Local hosts defined in /etc/hosts using 127.0.0.1 address.
# VM's setup via ievms.sh - the user listed below must be an admin on the VM.
#
# OVERVIEW :
# 1 Parse local (127.0.0.1 ONLY) hosts to a list
# 2 Create a .bat file to copy to the Windows VM disk
# 3 Loop over hosts, adding commands to batchfile.
# 4 Copy batchfile to C:\ of Administrator in the VM
# 5 Execute the batch
#
# For info on getting UAC on Windows from within batch script see

#
# USAGE:
# Call with Virtualbox VM name, or without args to see usage.
# hosts-to-vm.sh "VM - Name" [ "VM2 - Name" "VM3 - Name" ... ]
#
# To run on all
# ./hosts-to-vm.sh "IE6 - WinXP" "IE7 - WinXP" "IE8 - WinXP" "IE9 - Win7" "IE10 - Win7" "IE11 - Win7"

${SCRIPT}
USAGE
Specify at least one Virtual Machine to use.
Call the script as follows on the host
${SCRIPT} \"VM - Name\" [ \"VM2 - Name\" \"VM3 - Name\" ... ]
Edit this script if you want to avoid overwriting the Windows hosts file.
See OVERWRITE comment in get_hosts function in ${SCRIPT}
${SCRIPT} \"VM - Name\"
A hosts.bat is generated, copied to the VM and then run.
The VM will launch, the Windows Console should open & disappear.
The hosts.bat can be re-run, it will request admin priveledges via UAC
The batch file will remain in the users home directory.
UAC on Windows 7 - USER INTERACTION REQUIRED INSIDE THE VM.
Manually agree to run the hosts.bat file with admin privileges on Windows 7 VM's.
The new hosts file in Windows uses the hosts IP address,
127.0.0.1 would resolve to the VM, not the host OS.
Ensure the guest has a static IP on the primary interface or
re-run this script to overwrite the hosts file.

Per link in http://stackoverflow.com/a/17094284/406725

ievms by default creates VM's titled: IE7 - WinXP

To account for passing in arguments with spaces ( VM names ) change:

# line 79:
for VM in $@
# to:
for VM in "$@"

Or you can copy my fork ( change + comments ): https://gist.github.com/chaffeqa/8922736/revisions

Does this still work? The Administrator/Password1 combo doesn't let me log in. Using IEUser/Passw0rd! does let me log in but nothing appears to happen when I try to exec the bat file:

VBoxManage guestcontrol "IE9 - Win7" exec  "/Documents and Settings/IEUser/Desktop/hosts.bat"    --username IEUser --password Passw0rd\!  --verbose
Opening guest session as user 'IEUser' ...
Waiting for guest session to start ...
Guest session (ID 2) has been started
Starting guest process ...
[2588 - Session 2]
Guest session detached

Inspecting the Windows hosts file shows it hasn't been updated.

Thanks chaffeqa, I have probably botched the merge, but it should be there now.

airblade, this should work now.
The Windows 7 VM's needed to request admin level access & that was failing along with the new user & password.

Apologies for being slow to resolve this - if you know how I can get notifications from github comments that would be great :)

@drewreece It works now – fantastic!

Not sure how to get notifications from comments; I assumed they happened automatically.

Great, thanks for the input.

I expect the notifications are off because gists don't support them or maybe I have a cheapskate free account :)
