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. -- will
Re: can't complete reservation
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.

Re: can't complete reservation
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?

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 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.

Re: can't complete reservation
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. will On 07/11/2012 01:43 PM, Michael Jinks wrote: 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?

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 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.

Re: can't complete reservation
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 On 07/11/2012 02:22 PM, Josh Thompson wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 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.
