Linux KVM: Bridging a Bond on CentOS 6.5

Mon, 27 Oct 2014 00:00:00 +0000

Today we are going to hop back into the KVM fray, and take a look at using CentOS as a hypervisor., and configuring very resilient network connections to support our guests. Of course these instructions should be valid on Red Hat Linux and Oracle Linux as well, though there is a little more to be done around getting access to the repos on those distributions…

I am assuming this is a first build for you, so this step might not be applicable, but it won’t hurt anything.

Installing Linux Integration Components v2.1 Beta

Wed, 31 Mar 2010 00:00:00 +0000

On March 31, 2010 Microsoft released the beta of version 2.1 of the Linux Integration Components. The Linux ICs allow Linux VMs running on Hyper-V to be “enlightened” and have access to synthetic device drivers which perform much faster than their emulated counter parts. It can be downloaded by registering for the Linux Integration Services for Hyper-V on http://connect.microsoft.com

What is new in Linux Integration Components v2.1 Beta?

There are three new features, time sync, shutdown, and SMP. Time sync is communication through the vmbus which updates the guest’s time to match the hosts (without this time is only synced on boot up of the VM). Shutdown simply makes that little shutdown button in Hyper-V Manager work, previously you only had the option of using the Stop command or entering the guest via ssh or some other mechanism and initiating the shutdown. SMP is some fixes in the vmbus module which make the module SMP-safe, and in addition Microsoft will now support Linux guests (RHEL 5.3 & 5.4, and SUSE 10 & 11) with up to 4 vCPUs, previously only 1 vCPU was supported. InputVSC (Citrix’s Project Satori) will continue to work with this release.
