How to shut down Hyper-V Server 2008 R2 from acpupsd?

  • 772

I have several computers connected to a single APC SmartUPS 1500. The UPS status is monitored by a server running acpupsd. The other computers also have apcupsd installed, and poll the main computer over the network to get the UPS status, and they shut down if a power loss event occurs.

I want to add a computer running Hyper-V Server 2008 R2 (free version) into the mix, but as far as I can tell it isn't possible to install apcupsd or other UPS monitoring software in the hypervisor. How can I get this machine to shut down during a power loss event?

    Why not? I mean why isn't it possible? It is currently impossible to install the USB driver on x64 versions of windows, due to signing issues, but you only want to use the network client part, so I fail to see how that would be a problem. You'll just have to deal with everything from the command line.

    Hyper-V Server 2008 R2 is just a Windows Server 2008 R2 Core install with all roles but Hyper-V server disabled, some helper scripts, and the odd funky behavior here and there. If you say it is not possible from a licencing point of view, we talked with MS at this one place where I work, and they explicitly told us that things like backup agents, extended hardware drivers (HP OpenView agents, etc) and somesuch were not considered "usage", and were perfectly fine.

    In fact PowerChute Network Shutdown explicitly supports Hyper-V Server 2008 and Windows Server 2008 Core with Hyper-V role installs.

    I don't have any Core installs available in my lab to try it, but I'm fairly confident it would work, apcupsd has very little windows-centric requirements, it is just a service, which should in theory work. If not, a bit of hacking could make it work.

    If you report it does fail to work, I will setup a test vm with a Core install and give it a try, for kicks.

  2. Just use PCNS 2.23 Windows (last one that does NOT check against Hyper-V) & use the script:

    to run before shutdown

    Works a treat
