Hi Madhurranjan,<font color="#888888"><br></font><br>Regarding your first question, you can't modify an existing VM. You'll have to modify the source template, and then shutdown the current VM and create a new one.<br>
<br>About the second one, your proposal seems reasonable. I'd say that the optimal values depend basically on your infrastructure and the kind of workload you'll have to deal with; so I can't really help here.<br>

Hi All,<br><br>I have had VMs in the pending state for a while and I went through this thread(<a href="http://lists.opennebula.org/pipermail/users-opennebula.org/2011-April/004680.html" target="_blank">http://lists.opennebula.org/pipermail/users-opennebula.org/2011-April/004680.html</a>) and basically figured out that there are no CPUs left to allocate VMs, though there is plenty of RAM. Manual deployment works I had 2 questions regarding this scenario:<br>
<br>1. I have close to 20VMs on one of the boxes and had allocated 1 CPU each , so that has taken up 20CPUs. Overall the system has 16CPUs(4 CPUs , each being a quad core). Now , can I re-allocate CPUs for these VMs to 50% or less than what they are currently ? Can I do this at all in the first place ? Require your thoughts on this point.<br>
<br>2. What is a good allocation number for CPUs ,if I want to create something like "Small" , "Medium" and "Big" VMs ? I can do this with RAM since the box has good amount of RAM but not sure what parameters I should take for CPU. The CPU in my case seems to be the factor that doesn't allow more VMs to be allocated by the scheduler. Can I have for eg, <br>
Small VM - 0.25 CPU <br>Medium VM = 0.5 CPU <br>Large VM - 1 CPU<br><br>thanks<br><font color="#888888"><br>Madhurranjan<br>
