Hello, I successfully captured the image from a linux vm in ESXi 4.1, thank you Andy. But I couldn't find a way to reload/deploy it to other vm guests.
I have found that the image is captured and stored at two locations: 1) at management node: /images/vmware_images/vmwarelinux-centos_image1011-v0/vmwarelinux-centos_image1011-v0-flat.vmdk 2) at ESXi datastore: /vmfs/volumes/datastore1/vmwarelinux-centos_image1011-v0/vmwarelinux-centos_image1011-v0.vmdk VCL web interface also shows the new image 'centos_image10' under Image_Manager => Image_Profiles. Strangely the original vm guest was deleted from ESXi datastore by VCL. I don't worry about that too much at this moment. I tried different settings when deploying the new image and they all failed somehow. Attached is a cut from /var/log/vcld.log, hopefully I can get some quick help from more experienced eyes.

When the capture process failed, the VCL request (request.id = 14) was left in the database and its state was changed to 'maintenance' (request.stateid = 10). To restart the image capture process, all you need to do is change request.stateid back to the 'image' state (request.stateid = 16) and your running vcld daemon should restart the process. You don't need to run 'vcld -setup' again. There is currently no web interface or utility to change the request state so it will have to be done manually to the database. You'll probably want to install phpmyadmin if you haven't done so already. The statement to update the request state: update request set stateid = 16 where id = 14; The VCL daemon will begin processing the imaging request again within a few seconds. Run 'tail -f /var/log/vcld.log' before executing the SQL statement to watch the progress. Hope this helps, Andy John Ma wrote: > Hello, > > I am new to VCL.
