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: Max Number of VMs per Host
Normally, you can calculate the average number of VMs depends on the computing power (CPU). For example, 1 physical core can supports 2 VMs with 2 GB RAM. If you have 2 CPUs with 16 cores, then you might run 32VMs with 64GB RAM. However, the max number of VMs per host depends on variable facts as Al Quiros mentioned, In addition to Al's comments, you might also consider the application you want to run on guest VMs. If applications are more computation intensive, the number of CPUs would be important fact to decide the max number of VMs per host. In our environment, we don't use VMware but running RHEL 6 x64 with KVM on IBM blade hosts with 16 CPUs and 24GB RAM. We run average 15 Windows XP VMs with 1GB memory without much performance overhead. However, we can run up to 22 VMs but the performance was not good.

As a general guide, I have found the following to be reasonable. Other admins, please share your opinions. For a single VM host with 12 virtual CPU and 98 GB RAM, I typically allocate 25 Windows VM. When necessary, I have raised it to 32 Windows XP machines. For linux based images, I have used 50 VM without issues. Monitor the performance tab on your vSphere client to see if the host is over-worked. On Virtual Machines that require higher performance, I usually will not place them on a host with more than 10 working VM. But the most important thing is to watch the performance closely. You will get a feel for how many VM per host by experience. As always, your mileage may vary.

Re: openstack and VCL ?
Hi Aaron, I've been also working on Openstack plugin for VCL and finished the POC test on Openstack Essex with Ubuntu 12.04 x64 server. The reservations works but there are still some issues on capturing (or snapshot) images in Openstack Essex. If you can create jira issue, I could post my initial work in details and share some configuration tips with others. Thank you.

Hi Young, At the moment we've tested our module with Amazon EC2 and OpenStack's Cactus release. Provisioning works, though there's still a few issues that need resolving. We're also still deciding the best approach to take with image capture, especially for Windows images. We definitely want to get everyone's thoughts on this once it's open sourced. It'll be great to get a chance to talk with you at the conference. Cameron On Thu, Apr 12, 2012 at 9:55 AM, Young h Oh o...@us.ibm.com wrote: Hi Cameron, Sounds great.
