Virtualisation

ack in Jan 2010 I wrote a script which shut down the virtual infrastructure, this was used to ensure your VMs were shut down and then your hosts were shut down in an orderly manner, ideal for things like UPS shutdown scripts etc. A slight spin on that is a Start-Up script, I was asked by a couple of people if I had one of these, it also becomes more relevant with the vCenter Virtual appliance, no need for HA and DRS rules or to manually search for the vCenter Virtual Appliance if there is a power outage. The script below will... [Lire la suite]

In this blog post we looked at the new support for vendor neutral discovery protocol LLDP in vSphere 5. Unfortunately LLDP is only available on the Distributed Virtal Switches and not for ordinary vSwitch. However, for a long time we had CDP (Cisco Discovery Protocol) in the vSwitches, but as the name implies is a Cisco proprietary method. If running Cisco devices this is no problem, but for example HP Procurve has no full support for CDP. This means that they cannot send any CDP data, but is actually... [Lire la suite]

Ca fait plus de 4 mois que vSphere 5 est sorti et même si la sta­bi­lité de cette pla­te­forme n'est plus à démon­trer, il est tou­jours bon de jeter un coup d’œil du coté des KB avant son ins­tal­la­tion ou son upgrade.

If you’re planning to test the beta of Windows 8 when it arrives early next year, you’d better start thinking about your hardware now. One of the killer features of the new operating system, Hyper-V virtualization, is picky about hardware. Here’s what to look for. Are you planning to test Windows 8 when the beta release arrives in February? If so, you’d better start thinking about your hardware now. You might have your eye on a surplus PC as a Windows 8 test bed. A two-year-old PC seems like a perfect candidate for a test... [Lire la suite]

I had an interesting discussion recently with a number of my colleagues around the requirement to place additional uplinks (vmnics) on a virtual switch that are not used by iSCSI binding into the 'Unused' state. One would think that it might be useful to team these uplinks, placing some in Standby mode so that in the case of a failure on the active link, the iSCSI traffic could  move to the standby uplink. But the requirement is that other vmnics must be put into the 'Unused' state and not teamed. Why? This requirement... [Lire la suite]
