Learning Hyper-V management can be a bit tedious for administrators who are new to Microsoft Hyper-V virtual machine manager in cloud business. There are many optimized techniques that the administrators often learn so late. Here are 15 mistakes highlighted for administrators when managing Microsoft Hyper-V environments.
Many administrators do a common mistake: Hyper-V virtual hard disks (VHDXs) for everything.
VHDX, despite being beneficial in many ways, are mostly wasteful.
Imbalance of Memory and CPUs
Microsoft recommends a maximum of 12 virtual CPUs per physical core. Keeping this in mind, it is necessary to have a balance between CPUs and RAM. Using a Performance monitor tracing helps you get that balance so that you do not run out of memory before you run out CPU.
Blindly Accepting VM Configuration Defaults
Most people often overlook the options while configuring the VM and end up accepting the default settings. In reality, you only get to have one vCPU in the default settings and the Virtual memory is set to 1 TB (you pretty much would never need this much of Virtual memory, honestly!). For guest OS XP/ Server 2003, the requirement automatically becomes at least 2 vCPUs. By accepting default configurations, you might end up risking the distribution of resource allocation by the host.
Imbalance of SSD and Spinning Disks
For optimal Hyper-V server manager settings one good Hyper-V Management practice is to have a balance between SSD and spinning Disks via the Hyper-V virtual machine manager. In ideal case, an SSD churns the spinning disk while the Hyper-V server is installed directly over it. So, the SSD’s fast speed must be leveraged on to work with the VM data.
Not Joining a Domain
Joining a Domain is another sane thing to do for better Hyper-V Management. Generally Hyper-V hosts should never reside on a perimeter network. Leaving a host in a work-group makes it vulnerable to attacks. An attacker can penetrate and get unauthorized access to all VHDX files.
The golden Tip: Don’t Avoid PowerShell
It is without a doubt that PowerShell requires some effort to learn, however, once administrators get their hands on the awesome tool, they can easily manage multiple tasks in parallel. PowerShell allows the users to get access on the following:
- .NET Framework API
- Windows Management Instrumentation
- Windows Component Object Model
- Command Prompt
- PowerShell Commands
