Subject: [Engine-devel] Question about HotPlug



Hi all,

Currently there is an option in the "vdc_options" table which
indicates the
operating systems that do not support NIC hotplug. I think it would
be a
better idea to use the osinfo properties file to enable or disable NIC
hotplugging, since in this file an operating system can inherit
properties
from another one. The main idea is to disable NIC hotplugging in
PPC64 VMs,
but listing explicitly every ppc64 os in "HotPlugUnsupportedOsList"
config
value does not look like a clean way to do so. Do you agree with this?
Should this parameter be included in the osinfo properties file?

The hotplug capability of the OS refers also to disk hotplug in
addition to
vnics hotplug.

The VmCommand.isOsSupportingHotPlug() handles the logic of the
operating systems
that don't support hotplug.

+1 for moving it as a parameter in the osinfo-defaults.properties for
the relevant
os.

+1
I'd also separate between hotplugdisk/nic
(and from what i hear, for some operations like cpu/ram, we'll need to
distinguish between hotplug and hot unplug, but this can wait for them)



+1 whats the namespace you had in mind for it?
e.g.
os.{id}.hotplugSupported.network.value = true

or an existing devices namespace is also an option:

os.{id}.devices.network.hotplugSupport.value = true







Thanks,
