Hello to you all! We are implementing here at the University KVM virtualization for our servers and services and i was wondering if anyone virtualized domain cotrollers to KVM. Does anyone done this before? Any advice? -- Andry Michaelidou Papa | IT Systems Administrator|Department of Computer Science| University of Cyprus Tel: +357.22.892734 | Fax: +357.22.8927231 | http://www.cs.ucy.ac.cy -------------- next part -------------- An HTML attachment was scrubbed...

Hi, We currently run AD virtualised (Xenserver, but it shouldn't really matter). When running Windows on KVM make sure to use virtio (paravirt) devices for improved performance.

[CentOS-virt] Domain Controllers virtualized KVM
Hi, Our domain controller and our file/print server (Windows Server 2008 R2) are running as KVM guests under CentOS 6 since 2011 and we didn't have any issues with them. I use the virtio network and disk drivers on the virtual machines. The performance of the domain controller is very good (more than what we need in fact) but we have a small network, about 40 desktops and 30 laptops. I use local storage on the KVM host for the virtual disks, they are in QCOW2 format. (make sure to use metadata preallocation when you create the disks if you use QCOW2) ---- *Jean-Fran?ois Juneau* // Administrateur r?seau - System administrator // (819) 477-5353 #2222 AOF Service Alimentaire | www.aof.ca ---- N'imprimez pas ce message si ce n'est pas n?cessaire Le pr?sent email peut contenir des renseignements confidentiels et ne s'adresse qu'au destinataire ou qu'? la destinataire dont le nom figure ci-dessus.

Any advice?If you need to support restoring your Windows domain controller VM from a snapshot or you need to live migrate it then you need Server 2012 and a hypervisor that provides a VM generation ID. I don't believe KVM supports this and it's only available in Xen in the upcoming Xen 4.5 release. David
