Hi,<br>
<br>
Sorry for the late reply, I wasn't in the office last week.<div><br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
The attribute VM/TEMPLATE/CPU should exist if the user defined the CPU<br>
in the template. But CPU is an optional value.<br>
You said that you bill by resource allocation; are you taking into<br>
account this optional attribute?<br>
</blockquote>
<br></div>
We consider 1 cpu core + 8GB of memory to be equal to 1 "cloud unit". Out billing is based on a report that takes this into account. We use the information from the opennebula vm_pool table.<br>
<br>
Looking at the template in the sunstone interface (tabs at the bottom), we see both CPU and VCPU listed. However, when I look at the javascript array object used to fill in the vm table in sunstone, CPU nor VCPU were present.<br>
<br>
Apparently there is a difference between getting the INFO from a VM and the POOL_INFO from the pool of VMs.<br>
<br>
I tried to figure out where in the code this difference was made, but I could not put to much time in this and had to leave it.<br>
<br>
(Please remember this is all 3.2.1. It might be solved in 3.4.)<div><br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
If you bill users depending on the CPU and MEMORY attributes, maybe<br>
opennebula should provide a way to make any attribute mandatory... We<br>
could add a new section to oned.conf, similar to the restricted<br>
attributes [2] (introduced in 3.4). For example,<br>
<br>
VM_MANDATORY_ATT = "CPU"<br>
</blockquote>
<br></div>
This would actually not be a bad thing. At this moment, we are making some fields mandatory in sunstone, but when they use for example the xml-rpc, they can work around it. In the end they still get billed since we know from the vm_pool table what they used, but for the users, it might be a surprise. It would be better if an "incomplete" VM template would not instantiate.<br>
<br>
Of course, in our specific case, we would also like to enforce the rule:<br>
MEMORY = #CPU * 8GB<br>
<br>
But I do not see how this can be done in a nice way.<br>
<br>
Anyway, sorry again for the late reply.<br>
<br>
Best regards,<br>
