You probably know that the Linux Integration Services is a set of drivers that add quite a few important features to a few popular Linux distributions when run inside a virtual Hyper-V machine.
Linux Integration Services 3.5 new features
Most noteworthy is the support of Linux/CentOS 5.5 and Red Hat Enterprise Linux/CentOS 5.6 and the new github repository. The open source code has been released under the GNU Public License v2. Other new features are:
- Key-value pair: Passes information such as guest IP, FQDN, OS version, host name between guest and host
- Hyper-V specific video device: Offers high-performance graphics and superior resolution for virtual machines
- Dynamic memory ballooning: Enables Hyper-V host to reclaim memory from the guest until the Minimum Memory settings is reached
- Live virtual machine backup: Provides uninterrupted backup while the VM is running
- Virtual fibre channel: Links a virtual machine directly to SAN storage
- VHDX resize: Expands and shrinks virtual disks that are attached to a VM
The following two features were already available in version 3.4 and are now also supported for RHEL/CentOS 5.7-5.8.

- Physical Address Extension (PAE) kernel support: Allows access to memory larger than 4GB on 32-bit machines
- Static IP injection: Configures a static IP address on guest OS (important for Hyper-V Replica)
The Linux Integration Services 3.5 have already been available for download for a few weeks. Make sure that you also read the small print in Ben Armstrong’s post if you intend to use one of the new features.
Hi, not related to this article but noticed “news for sysadmins” has been removed from the streams menu. Dunno if anyone else misses it, but I thought it was very nice to see recent news regarding anything. Or maybe this is supposed to be accessed in some other way and I’m just stupid :)?
Babun, you are right, I removed the news stream for various reasons. At the moment, I post important news with a description in the blog (like the one you just read) and shorter posts with a comment or two in the forum (like this one). You can subscribe to the forums RSS feed or subscribe via email. I am currently testing if this is a viable solution. Let me know what you think.
