Description of problem: Hotplug/unplug is not supported. Can't hotplug or unplug vm's nic while it's running with OS. Version-Release number of selected component (if applicable): 3.4.3-1.2.el6ev How reproducible: always Steps to Reproduce: 1. Working setup with PPC host, run VM and install OS 2. Try to Hotplug/unplug nic that vm is using 3. Actual results: There is no option to change the card status. Hotplug/unplug is not supported Expected results: Hotplug/unplug should be supported Additional info:
This feature is blocked in the osinfo, if you change the line: os.other_ppc64.devices.network.hotplugSupport.value.3.5 = false to true, it will enable NIC hot(un)plugging. Is enabling it enough for it to work or are there other problems blocking hotplug support?
Hi Vitor, I changed the line in: vi /etc/ovirt-engine/osinfo.conf.d/00-defaults.properties - os.other_ppc64.devices.network.hotplugSupport.value.3.4 = true and then restarted engine. It enabled the hotplug/unplug support and it worked. - But why this feature is disabled by default?
It was not supported when the original oVirt ppc64 port was designed.
This feature is going to be enabled by default?
yes
Hi Vitor, If i'm adding new NIC to running vm, it should be added when it's plugged, right? Because now, when i'm adding new NIC to vm, it's added when it's unplugged. Is it should be a part of the fix too? or it's another bug? Best regards,
Just to be clear about this- The NIC added when it's unplugged to vm by default. and there is no way to change that.
This is another bug. Please open another bug with a detailed description.

Hotplug/unplug is not supported on rhel guest OS. -The guest OS must have a very recent version of the powerpc-utils package (>=1.2.19)
Added known issue release note text
Changing component based on the patches solving this bug. Vitor, can you sent the changed-in-version and move to QA?
do we have a RHEL child bug to include it? Or who's enforcing "-The guest OS must have a very recent version of the powerpc-utils package (>=1.2.19)" ?
el6.6 would have powerpc-utils>=1.2.20 https://brewweb.devel.redhat.com/buildinfo?buildID=355055
Verified on rhevm-3.4.5-0.1.el6ev.noarch
