edit quota screen shot
(In reply to Ilanit Stein from comment #0) > Description of problem: > For a data center, with quota definition of 1 single vCPU, > Try to hot plug a vm from 1 vCPU socket to 2. > The quota vCPU consumption is marked as exceeded. The above description is the correct definition for quota- limiting the resources a user / group may consume. - If you set a quota of 10 GiB, your disks' total cannot exceed 10 GiB. - If you set a quota of 2 GiB RAM, the total RAM consumed by your VMs cannot exceed this number. - The same applies for vCPUs. Regardless of hot or cold plug, you are not allowed to exceed this limitation. The above is the design of quota limitations. Please explain if your case aligns with the definitions. If not we should close this issue as this is doing exactly what we want. Created attachment 896751 [details]
Datacenter Quota tab
The problem described here is not that operation of increasing the number of cpus, above limit - this is of course, the expected behaviour. It is about having the Quota marked as exceeded (in red), see attached 'Datacenter Quota tab', though it was not exceeded. The limit was 1 vCpu, and that was what defined. The trial of increasing the vCPU from 1 to 2, had made quota marked as exceeded, though, it didn't. Just to clarify, so the issue here is that failure to hotplug cpu due to quota limitations keeps the resource report as exceeding although the hotplug action failed?

Yes.

The only real issue Ilanit and I saw is that when quota is on 100% cpu it is reported as exceeded. I will fix that. this bug status was moved to MODIFIED before engine vt5 was built, hence moving to on_qa, if this was mistake and the fix isn't in, please contact rhev-integ This bug cannot be verified, till this bug will be fixed: bug #1151827 Following bug #1151827 is fixed, Verified on vt6. For a vm with number of cpus = quota limit, Try to hot plug number of cpus, above quota limit fail (expected), and in quota tab it is still marked as 100%. rhev 3.5.0 was released. closing. |
