    hyper v server 2008 r2 and ups

    ive been doing a bit of work on looking into hyper v server 2008 r2 and was wondering how you would connect a ups to it as the clients dont support usb so i cant install the software on one/more of those and i assume as hyper v server 2008 r2 is core based i cant install the normal apc powerchutes software

    thinking about it i assume you would need to use networked ups variants on clients but that still wouldnt shut down the host

    AFAIK, APC PowerChute Network Shutdown 2.2.4 supports installation on Server 2008 R2 Core. Earlier versions don't support it.

    You need to get a special version of powerchute to install.

    Anyway when you shutdown a hyper v host the virtual machines save the state by default. You can change this so the virtual machines can shutdown. So when powerchute shutsdown the host the virtual machines should be ok.

    im assuming then i need networked ups's rather than what for me are normal serial/usb ones?

    and presumably the software is installed via cmd prompt (again i assume apc provide instructions as atm i have no ieda how to config it)edit just found it on apcs site though their java instructions are about as clear as mud lol

    That would be correct on both counts from what I've seen. I've not done it myself.

    However... There may be an alternative in the form of this project - Apcupsd, a daemon for controlling APC UPSes

    i tried that when 8.01 software wont work if it detects hyper v role and i couldnt even get it to find the ups on a normal 08 server. So more expense for my schools as it seems a bit overkill when theres one server to have a networked ups

    How about a different route - if you've got any non-hyper-V server box, could you not have the UPS plugged into that via normal methods, and get it to send a remote shutdown command to the Hyper-V host?

    atm im looking into just using hyperv server2008 r2 on the box and virtualizing the actual server(s) so if needs be i can quickly get them back up again if it all goes wrong (assuming its not the disks atm as ive not looked into backing up the vhds on the fly and as some may be absolutely huge i probably wont have space to back up data partitions anyway so will just back up c drive as a vhd then restore d from normal backup (atm usually a robocopy to a nas box)

    Came across the following article today and thought it would be worth posting since it seems relevant to this thread.

    http://www.virtualizationadmin.com/a...r-v-Part2.html

    Basically, it says you need to use a special version of PowerChute called PowerChute Network Shutdown for Hyper-V (~£60) which gets installed on the host OS and shuts down VMs over the network. It's worth reading the article since it mentions a few caveats too.

    If you are running Server 2008 R2 with Hyper-V Role enabled you can install version 2.2.3 and use a small script to help with the virtual machine shutdowns.
    BUT if you have server 2008 R2 CORE installed then you will have to purchase "PowerChute Network Shutdown for Hyper-V" (now £80) as 2.2.3 does not support a core install.

    Nice little money earner for APC there, especially as everywhere is turning to virtualisation. Aparently the 2.2.5 software just has a block on the installer when it see`s the hyper-V role is installed.

    I'm just looking into shutting down hyper-v virtual machines. I'm a little worried about the time it takes for hyper-v to finally shut them down.

    What kind of script would you recommend?

    I'm using hyper-v with the GUI so it should be easy you would think!

    there is a version of powerchutes free downloadable 8.5 if memory serves that will install with hyperv enabled and as a normal pc shutdown triggers hyperv to save state / shutdown vms that should be all you need (if you actually watch the console at shotdown it shows it closing hyperv instances. IIRC though the version that still ships on the cd is 8.0? and wont install eith hyperv tuned on

    all you need to do is have the hyperV host to shut down sanely. Within hyperV itself, you can set what happens to the client machines when the host shuts down.

    Just thought I'd point out that you don't have to run 2008 r2 core to run hyper-v, it works perfectly fine on the full install. Also as has been said, hyper-v can control what happens to the virtual servers when it attempts to shut down.

    Also, using hyper-v, I'd strongly recommend having at least one physical DC.
