Reservation Ending Warning

[Junaid Ali <al...@iit.edu>]

Hello,

I remember in the past versions of VCL there used be a warning window
showing up in Windows VM’s reminding the user that the reservation is about
to expire. It doesn’t seem to be working with Windows 7 VM’s on VCL 2.3.2.
Any ideas?



Thanks.

Thanks Aaron. That worked.
If there is interest in making this change to the main source code
attached is a patch.

Thanks.

This problem affects 64-bit Windows 7 images and relates to the fact that
msg.exe is not on the PATH for cygwin users (this has to do with the
"bitness" of the executable). So, when vcld tries to run the command `msg
$user /TIME:180 '$message'`, the remote machine responds with an error
(probably some version of "file not found", if I remember correctly).

The way to fix this is either
a) Make sure that /cygdrive/c/Windows/Sysnative is part of the PATH for
your base images (and therefore for all of your derived images)

or

b) Edit the notify_via_msg subroutine in lib/VCL/utils.pm, prepending the
msg command with "export PATH=..." like so:

my $command = "export PATH=/cygdrive/c/Windows/Sysnative:\$PATH; msg $user
/TIME:180 '$message'";

Regards,
Aaron
