Re: Using VMware as the Hypervisor
There are a bunch of images in the system and when you request to load an image from VCL website, it save your request in the database. and then in the management node, it checks for new request and copy the requested image to another place and change the VMX file and then call ESXI to register the Image.

Re: Using VMware as the Hypervisor
Arbin, VCL is using non-persistent disks for all reservations. There is nothing to copy/load during reservation since all ESXi hosts use shared storage for all VM Images (Data Store Path: this has to be on shared datastore). Then you have a 2nd datastore where ESXi keeps deltas for running images (VM Path: this can be local or shared datastore). During reservation, VCL will 1st check if there is an available computer with the image requested. If there is one then it will be used for current reservation (this when you see load times 1 min on GUI). If there is no image available then VCL will create new VM (create .vmx file and upload to ESXi host and register it). The new VM will use non-persistent disk(s), so no .vmdk copied. This process takes time needed to create VM and start it on ESXi host. When you create new image or update existing image VCL will copy .vmdk files, which sometime takes considerable amount of time. -- Thank you, Dmitri Chebotarov Virtual Computing Lab Systems Engineer, TSD - Ent Servers Messaging 223 Aquia Building, Ffx, MSN: 1B5 Phone: (703) 993-6175 Fax: (703) 993-3404 On Tuesday, May 15, 2012 at 15:45 , Sanders, Arbin D wrote: Thanks!
