Hi, We have setup the environment for VM provision on ESXi recently. We are confused about some mechanisms:
- Images are stored in NFS As I see, VCL stores images in NFS and just copy it locally when using it. It means that the hardisk in the esxi hypervisor will not be used. All the VMs are stored in remote computer and all the operations will be remote operation (CPU exsits in Hypervisor but hardisk exsits in NFS). I think it may lead performance problems. Although we can setup mutiple NFS servers, it is not good that the hardisk in the hypervisor is not used and all the operations will be remote in my opinion. Why not transfer the image to the esxi hypervisor which will run the image? - Image reusing When we use an image from repository, VCL does: 1. copy the image form /golden/<image_name> to /inuse/<image_name>, 2. start the image. It's difficult for image reusing. It's impossible for mutiple machines to use the same image because the copy operation will only copy one image to the /inuse folder and that image can be used only for one esxi hypervisor. Other copy operation will overwrite that image. Again, if we transfer the image to hypervisor, there won't be such problem. -- Best wishes, 乔木 MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University TEL: 15991676983 E-mail: qiao...@gmail.com
