can't complete reservation
hello all,
i've successfully created a base image and have its privileges configured for
base users. i'm trying to create a reservation, but vcl always says the
requested time is not available even though there are no other reservations
configured and the time grid is entirely green. could this be an issue with the
image itself? log doesn't seem to indicate where the problem may lie. TIA.

thanks all,
i think i am on to something. it turns out i underestimated the number of
check-ins the management node does, and i did not go back nearly far enough to
catch the issue (i had a 2 hour gap before i could troubleshoot). the logs show
the vm not responding to pings and they also show the public ip not getting set
correctly. apparently, i have a typo in the mysql database that i need to track
down.

Will,
Here is a list of things to check from a previous thread (some already
covered):
- -image is in an image group
- -image group is mapped to a computer group
- -computer group contains computers in the "available" state
- -you have an active management node (it is updating lastcheckin in the
management node table)
- -management node is in a management node group
- -management node group maps to a computer group containing specified computer
from above
- -schedule for computer is available during the selected time
- -platform for image matches platform of computer
- -privileges set up in Privileges section of site to allow you to access image
and computer
- -specs of image (min RAM, min CPU speed, etc) are at or less than specs of
computer
- -no other entries in the reservation table for the computer that overlap with
the selected time period
If you are familiar with php, you can trace through the isAvailable function
in utils.php to see where it is returning.

the image is loaded on a vm (though it is not currently powered on) and it is
associated with a virtual host. i have checked the specs of the computers and of
the images. i did notice, however, that the advanced options of the image seem
to revert back to default after pressing "confirm changes". this is what led me
to think that it may be a problem with the image.

Mistake we often make: Is the image loaded on at least one virtual
computer, and is that computer associated with a virtual host in the
list on the Virtual Hosts page?

Will,
Make sure you have done all of the steps here:
https://cwiki.apache.org/confluence/display/VCL/Granting+Access+to+a+New+Image
The RAM, CPU, etc requirements Young mentioned are both specs of the computers
and the images. Images have minimum specs listed. Computers have actual
specs listed. The scheduler will not assign an image to a computer that does
not meet the image's minimum specs. You can check the image minimum specs
under Advanced Options where you edit the image. You can check the computer
specs where you edit the computer.
There won't be anything in vcld.log about this because a reservation never
gets created to be processed.

Will,
Did you check RAM, CPU speed, and others in 'computer' table that are
sufficient for the requirement of images? If they are not enough for the
image requirement, VCL cannot reserve images.
I think if you post the snippet of the vcld.log, it would be useful for
others to help you.
Thank you.
