Description of problem: When trying to Hot plug CPU along with Memory hot add, the cpu hot plug operation succeed, but the Memory new value seem to not propagated correctly to RHEV. For example, For a VM with sockets=1, cores per socket=1, and memory=100M, guaranteed memory=100M, VM reconfigure: CPU sockets1->4, and memory 100M->256M. This request succeed: VM Reconfigure for: vm - Memory: 256 MB, Processor Sockets: 4, Processor Cores Per Socket: 1, Total Processors: 4 Last Message VM Reconfigure complete On RHEV side, the CPU hot plug succeed, but the memory hot add fail on value not being a multipy of 256M (though the value entered on CFME side was 256M), therefore it seems the memory new value was not passed correctly to RHEV. RHEV Events: Jul 14, 2016 6:47:11 AM VM vm configuration was updated by admin@internal. Jul 14, 2016 6:47:11 AM Hotplug CPU: changed the number of CPUs on VM vm from 1 to 4 Jul 14, 2016 6:47:10 AM VM vm was configured with 100mb of memory while the recommended value range is 256mb - 65536mb Jul 14, 2016 6:47:09 AM VM vm configuration was updated by admin@internal. Jul 14, 2016 6:47:09 AM Failed to hot set memory to VM vm. Underlying error message: Cannot hot set memory VM. Plugged memory must be multiplication of 256. Version-Release number of selected component (if applicable): CFME 5.6.0.11-rc2.2.20160614152915_f315c68 RHEVM-3.6.6.2-0.1.el6 How reproducible: 100% Actual results: 1. The request for setting CPU hot plug & Memory hot add together, Succeed. 2. Memory hot add value is not propogated correctly to RHEV, if done along with CPU hot plug. Expected results: 1. The request for setting CPU hot plug & Memory hot add together, should Fail, if one of these operations fail (memory hot add failed in this case) 2. Memory hot add value should propogate correctly to RHEV, if done along with CPU hot plug.
Retested on CFME-5.7.0.9 (appliance leased from Sprout) and RHV-4.0.4 VM Reconfigure: cpu sockets 1->4, memory 100M->256M CFME request failed: Description VM Reconfigure for: test_hot - Memory: 256 MB, Processor Sockets: 4, Processor Cores Per Socket: 1, Total Processors: 4 Last Message Error: [Cannot edit VM. Physical Memory Guaranteed cannot exceed Memory Size.] RHV VM event: Failed to hot set memory to VM test_hot. Underlying error message: Cannot hot set memory VM. Plugged memory must be multiplication of 256. The VM was not updated.

Is this a dupe of bug 1388964?
(In reply to Dave Johnson from comment #4) > Is this a dupe of bug 1388964? No. bug 1388964, is a duplicate of Bug 1389303. I added a comment on that in bug 1388964. In this bug, the problem is not that the submit button is not responding, but rather the RHV error, on memory hot add is not propagated to CFME.

Juan - should this be on post? Was it backported?
It isn't backported yet. I am moving it to POST.
'ovirt' gem version bump PR: https://github.com/ManageIQ/manageiq-gems-pending/pull/7
The fix for this issue isn't completely correct, it doesn't work well with oVirt 3.6. The following additional pull request is needed: Don't send 'next_run=false' to oVirt 3.6 https://github.com/ManageIQ/manageiq/pull/13677
Satoe, shoud this be moved back to ON_DEV?
That sounds good, moving.
Juan - this should be at least on POST, right? Wasn't it on the 5.8.0 build?
Yes, it has been merged and backported, moving to POST.
Verified on CFME-5.8.0.11/RHV-4.0.7: VM Reconfigure: cpu sockets 4->1, memory 100M->256M CFME request succeed. On RHV side, VM memory updated to 356 MB (as expected, memory delta is rounded to 256MB), and CPU hot unplug failed on: "Hot un-plugging a CPU is not supported for cluster version 4.0 and architecture x86_64." As this bug do not handle the cpu hot unplug (see doc text), moving bug to verified.
