Solved! VMFS File Locking in VMware View 5.1 – All You Wanted to Know

Ever wonder why VMware View would support more than eight hosts in an ESX cluster? Wonder no more. VMware View 5.1 now supports up to 32 hosts in an ESX cluster! That is provided a NFS data store is specified for linked clone replica creation. Since more than eight hosts can now be used in an ESX cluster, VMware View 5.1 makes desktop consolidation even more efficient than ever before. I recently reviewed a technical white paper that discusses VMFS File Locking and Its Impact in VMware View 5.1 and the number of hosts it can support... [Lire la suite]

What physical computer am I on?

Once you start to get more and more virtual machines, and more and more Hyper-V servers, in your environment it can get quite hard to keep track of where a specific virtual machine is actually running. System Center Virtual Machine Manager can help you out here – but what if you are not sitting at the  System Center Virtual Machine Manager Console?  What if you have used Remote Desktop to connect to the virtual machine?  What do you do then? A long, long time ago – I posted information on how to figure out the... [Lire la suite]

Moving a Virtual Machine Between Hyper-V Hosts

A virtual machine (or VM) is an entity that is stored on one virtualization host, and that runs an instance of an operating system and uses resources that are presented to it by the virtualization software on that host. In Hyper-V, a VM uses a set of configuration files, and one or more virtual disks (in the format of VHD files). There may come a time when there is a need to move a VM or more between virtualization hosts. I will not go into a debate of why this needs to be done, however, I will just mention that the most common... [Lire la suite]

USB Device Mapping to VM in ESX4 Does Not Work As Stated

1.0 Overview With the release of ESX4, VMware documented the inclusion of a USB Host Controller device that could be installed in to hosted Virtual Machines. This USB controller would allow the mapping of a host attached USB device through to a VM. However when you connect a device you can not map it to a hosted Virtual Machine. This is documented at the following locations: http://vmware.com/pdf/vsphere4/r40/vsp_40_admin_guide.pdf (Page 164)http://weblog.aklmedia.nl/2009/05/vmware-vsphere-esx4-is-arrived/ 2.0 Issue ...

Baisses de performance vidéo sur un hôte Hyper-V

Sur les serveurs hébergeant le rôle Hyper-V où une carte graphique contrôlée par un driver mettant en oeuvre les fonctionnalités d’accélération des performances graphiques est installée, il est fortement probable de subir certaines baisses de performance. En effet, comme l’allocation de la mémoire est assumée par l’hyperviseur, cela génère de nombreuses interceptions qui ralentissent le fonctionnement général de la plateforme. La solution : laisser le driver générique inclus avec Windows Server 2008 : VGA.SYS ou VGAPNP.SYS. ... [Lire la suite]
