Nesting Hyper V 2. R2 on ESXi 5. 5. Since joining Nutanix Ive had the opportunity to get exposed to Microsoft Hyper V 2. R2, as our platform supports the three most common hypervisors VMware v. Sphere, Hyper V, and KVM. Im now embarking on writing some Hyper V guides for Nutanix, and wanted a way to leverage my existing ESXi 5. Nutanix block to learn about Hyper V networking. While Im very familiar with VMware networking, this project presented itself as a great learning opportunity for Hyper V. This article will show you how to nest Hyper V 2. R2 on ESXi 5. 5. My first challenge in getting a proper Hyper V test bed setup was to deploy Windows Server 2. R2 on my ESXi 5. 5 express patch 4 host, then get the Hyper V role installed. Now what Im about to do is very unsupported, and Im only doing it for my personal learning and quickly deploy a Hyper V learning lab. After some extensive Binging and trial and error, Ive narrowed down the unsupported tweaks needed to successfully run Hyper V 2. R2 on VMware ESXi 5. Lets get to it 1. Deploy your standard Windows Server 2. R2 template. Mine happened to be fully patched, and included the spring update which gave us back a semi functional start button.

HW 1. 0 then you can follow William Lams tip and set the guest. OS to use to be windows. Hyper. VGuest. If you are using v. HW v. 8 then I just left it to the default windows. Save the VMX file and re upload it to the datastore, overwriting the old file. Right click on the VMX file and register the VM. Now I didnt need to do this, but saw some other users that had to configure this setting. In v. Center open the properties of the VM and change the CPUMMU virtualization option. Select the bottom option. Power on your VM, then login to Windows. Install the Hyper V role, and you shouldnt get any warnings. Ive been running VMware ESXi 4. HP MicroServer for a few weeks now and the following post is to summarise my findings and to answer a question many. This is the setup I use for all my ESXi hosts, except for the part about disabling failback. I didnt used to set the activestandby NICs for them and I found that. Reboot after the roll is installed, and now you are ready to rock and roll with Hyper V 2. Esx4.1to5.1_16.jpg' alt='Esxi 4.1 Hp' title='Esxi 4.1 Hp' />Slym Software v. Sphere Configuration Backup. Thanks for sharing your efforts with everyone I just set everything up and it is working but the esxi backup retention setting seems to be ignored, unless Im not understanding how the backups are done.

To test, I ran my scheduled task, manually, and a backup was created. I then added a one time trigger to my task that would perform another backup within a few minutes of me logging out of Windows. I did this to make sure the task runs when no one is logged on. It appears the second backup was created but it looks like it overwrote the first backup.
