Running Hyper-V in a nested VM

Reading Time: 2 minutes How you probably know is possible run Hyper-V role (or Hyper-V Server) in a VM using latest version of VMware virtualization products (vSphere and Workstation) because they also can “emulate” the hardware instructions (AMD-V or Intel-VT) needed of hypervisors like Microsoft Hyper-V (but also, for example, Citix XenServer). More complicated if you was to run Hyper-V in a nested VM inside Hyper-V (or some other virtualization platform that lacks of this “emulation” feature).

Issue in VMware vMotion that stop at 14%

Reading Time: 2 minutes Some weeks ago I’ve got an issue in a VMware vSphere 5.1 environment with vMotion that stop each operation at 14% with some strange errors. Also there were several VMware KB articles related to this issues, with different reasons. The error message was simple: Timed out waiting for migration start request. So the closest KB article was: vMotion fails at 14% with the error: Timed out waiting for migration start request (2068817). But none of the possible solutions were applicable to my case.

Reading Time: 6 minutes PernixData FVP is a Flash Hypervisor software aggregates server flash across a virtualized data center, creating a scale-out data tier for accelerating reads and writes to primary storage in a simple and powerful way. Was one of first (probably the first) to implement a fault-tolerant write back acceleration. In the previous posts I’ve described the installation and the configuration procedures of FVP 1.5 on vSphere 5.5, now it’s the turn of the final considerations and comments.

Was one of first (probably the first) to implement a fault-tolerant write back acceleration. As part of the PernixPro program, I’ve got the opportunity to test various version of this product that actually support all version of ESXi 5.x (so is not limited to the 5.5 version) and works both with the vSphere Client and also with the vSphere Web Client.
