Subject: (2.10) Hotplug: objects and constants additions
X-Git-Url: https://code.grnet.gr/git/ganeti-local/commitdiff_plain/bd7fed672527a9ab9950b52382e2c3b1590076be

(2.10) Hotplug: objects and constants additions

Add pci slot in NIC/Disk objects. This slot will be used only
by hypervisor code. Currently only KVM will use it and store it
temporarily in runtime files.
Add HOTPLUG_* constants to define device types an hotplug actions.

(fix) Add missing opcode parameter

In stable-2.10 opcodes.py is auto-generated from haskell ones.
Add hotplug* params to OpInstanceSetParams.
