Linux Integration Services v2.1 Now Available

Linux Integration Services v2.1 Now Available

  • Comments 9


Over on the virtualization team blog – Mike Sterling has just announced the availability of the Linux Integration Services v2.1.  And there is a lot to announce here.  Along with the previous support for our high performance virtual storage and network adapters – this release brings in the following new features:

  • SMP Support: All supported Linux distributions can use up to 4 virtual processors per virtual machine.
  • Integrated Shutdown: This means that you can finally shutdown Linux virtual machines directly from the Hyper-V / SCVMM management consoles – without needing to login to the virtual machine first.
  • Time Synchronization: Linux virtual machines will now have their clocks updated to deal with things like “saved states” just like Windows virtual machines.
  • Heartbeat: The virtual machine heartbeat allows you to confirm that Linux is still running and responding inside the virtual machine.

These integration services are supported on the following guest operating systems:

  • Novell SUSE Linux Enterprise Server 10 SP3
  • Novell SUSE Linux Enterprise Server 11
  • Red Hat Enterprise Linux 5.2 / 5.3 / 5.4 / 5.5

You can download the integration services here: http://www.microsoft.com/downloads/details.aspx?FamilyID=eee39325-898b-4522-9b4c-f4b5b9b64551

Cheers,

  • Any ideea on how to install theese IC's on Asterisk?

  • I would do this by installing Asterisk on one of the supported Linux distributions.

    Cheers,

    Ben

  • Are there any plans to provide support for Ubuntu, or would the integration tools work on Ubuntu if they were compiled from the source?

  • Any idea if/when these will be scheduled in the main Kernel development?

  • John

    I believe its all in 2.6.35 which is rtm very soon.  Although not many distros will use that kernel for a while.

    Prehaps someone else can confirm.  In the meantime if you are looking for a free option I use opensuse 11.1 which works well with the 2.1 ICs if you follow thwe install notes

  • Will this still work under Windows 7 Virtual PC ?

  • Sorry for the double post, I didn't realize there was a post about LinuxIC here.

    I haven't tried this yet, But I have run into a fairly serious issue using the Microsoft LinuxIC rpm for Red Hat on Centos VMs.  I've not yet narrowed this down to the broadcom nic teaming or the integration components, and I know Microsoft's policy is not to support nic teaming.  Disabling the team is not an option, as we need to have complete redundancy throughout the network.  The problem is as follows:

    After a live migration, the linux VM fails to send a gratuitous ARP.  Since the nic team rewrites the frames with its own MAC, the ARP table on the router still has the MAC address of the nic team on the server it just migrated off of.  Furthermore, the periodic arp polling that the nic team does still includes this address, so even if connectivity re-establishes, it keeps going up and down as the ARP table on the router changes.

    If I do an ifdown eth0 && ifup eth0 to force a gratuitous ARP to be sent, everything is fine.  Obviously that's not going to work when PRO Tips migrates a VM at 3 in the morning.  

    This problem doesn't exist at all with windows guests.  The gratuitous ARP is sent immediately after the migration and network connectivity stays up.  That is what leads me to believe this is a bug in the LinuxIC code.

    I sure would appreciate it if you can get this information to the right person!

  • This is an update to my previous comment.

    I have now removed the nic teams on both Hyper-V hosts and I am still experiencing the same problem.  When a linux guest live migrates, the gratuitous ARP is not sent like it is for a Windows guest.  This is on Server 2008 R2 Data Center Edition with all of the latest patches and recommended hotfixes.  I am running Linux IC 2.1 on Centos 5.5.

  • Hi Ben !

    Please support Debian and Ubuntu linux version on the next version Linux Integration Services

    Thanks
