Migrating to embedded PSC, mind the decommission order.

I recently migrated a few vSphere environments with external PSC’s to vSphere 7 and noticed some PSC leftovers afterwards. Now a lot is already written about the deprecation of the External Platform Services Controller (PSC) deployment model so I will not go into this. What I do want to highlight is the importance of the […]

Batch migrate VM’s with VMware Cross vCenter vMotion (Fling)

VMware already features Cross vCenter Migrations since vSphere 6.0. The biggest constraint for this feature is that you can’t use it via the vSphere Web Client if the vCenter Server instances are not in Enhanched Linked Mode and within the same vCenter Single Sign-On domain.

Unresponsive/BSOD VM’s on ESXi 5.1 and 5.5

Since a few days I got several customers complaining about unresponsive or blue screening VM’s (both Windows 2008 and 2012) on ESXi5.1 and 5.5 environments. Troubleshooting at the customer site pointed out that the vnetflt.sys driver was causing these issues. This driver is part of the vShield Endpoint components that are installed whenever you a) explicitly […]

Failed to attach filter ‘pxdacf_filter’

During a recent customer visit we had a testing environment available on where some VM’s couldn’t be powered on/vMotionned to some of the ESXi Hosts. The error message: An error was received from the ESX host while powering on VM xxxxx. Failed to start the virtual machine. Module DevicePowerOn power on failed. Unable to create virtual […]
