Hyper-V

Good performance

Availavility

Reliability

DR integration with third party solutions / partners

OS updates may require rebooting the server. Too many updates monthly

Integration with Microsoft System Center.

MS Windows administrative users have a head start with using Hyper-V as it is a familiar product.

It's very cost effective compared to VMware ESXi.

We manage Hyper-V using both System Center Virtual Machine Manager (SCVMM) and the in-build Hyper-V administration tool, the former being the main product we use as the built-in tool is very light on functionality, unlike VMware ESXi.

Management of storage is not great and quite a shift away from how VMware does it with ESXi; there is no separate panel/blade/window for LUNs/data stores, which means there is a lot of back and forth when trying to manage storage.

A dedicated client with all functionality in one place would be awesome.

Having the equivalent of ESXi's virtual console is something which is absolutely needed.

Speed of deployment.

Cost versus resources.

Automation and PowerShell accessibility.

Control System integration could be improved.

Better documentation.

Interchangeability of hard drives (VHD, VHDX, first gen/second gen).

Hyper-V allows us to test the software and tools on multiple operating systems

Hyper-V allows us to create multiple virtual machines on a single physical server

Hyper-V helps to reduce the cost and count of physical servers in data center

Microsoft provides great support and maintenance

Heavy work load application and database might face some performance issues

Disk management needs to improve

DR and Backup - Hyper-V can make backup copies of VM's and store them elsewhere.

Supports live migrations, storage migrations, and import/export.

Does not support macOS.

Clustered shared volume is difficult to implement at first.

Easy to create multiple virtual machines and manage multiple OS on a single physical hardware.

Easy to run software that require an older version.

Easy to test software on multiple OS.

Applications that requires GPUs for processing, does not work well.

High-precision applications have issues running on VM.

Microsoft gives us useful supports and maintenances, technical informations about Hyper-V and other related solutions.

We would like to be able to backup and restore cluster shared volumes and VM shared volumes more easily.

Useful data migration solution.

Support team is active and reliable.

Quality business data management functionalities.

Only setting the interface security when getting started with Hyper-V.

On feedback collection from multiple data processing operations.

Customizing deep functionalities of Hyper-V when new to the product.

Editing configuration of virtual machines.

Installing Windows operating system based VM client computer easier than rivals.

Efficient resource use and management.

Able to use usb drives for operating system installation without needing .iso file.

Dedicated gpu virtualisation could be easier for VMs.

The console interface could be improved and shows a small thumbnail of running machines.

Ability to create new machines.

Change the configuration of machines, like memory or CPU.

Export import virtual machines from/to another Hyper-V environment.

The network configuration for the machines is not that easy to set up. E.g. to have them contact the internet, for example, create VLANs.

Snapshot management can be a bit more user-friendly. A good overview of snapshots is missing.

The efficiency of resource usage can be better.

Easy to use GUI - very easy for someone with sufficient Windows experience - not necessarily a system administrator.

Provisioning VMs with different OSes - we mostly rely on different flavors of Windows Server, but having a few *nix distributions was not that difficult.

Managing virtual networks - we usually have 1 or 2 VLANs for our business purposes, but we are happy with the outcomes.

Hyper-V is very slow to adapt to trends in infrastructure and its features are very basic when compared to the offerings from VMWare and some other companies.

For instance, VMWare has implemented a built-in Kubernetes cluster provisioning feature (that comes with a specific license that costs extra of course).

Hyper-V's infrastructure monitoring is very basic and altering is non-existent. It's up to the system administrators to either create or install separate monitoring & alerting solutions.

Hyper-V cannot handle some virtualization needs all that well - my example is with VM backups and snapshots. Both of these are supposed to fulfill specific needs, but there are a number of gotchas in each of those cases (easily corruptible VHD files, gradually growing in size snapshots) that an administrator needs to address occasionally - administration overhead where you would not expect it.

Virtualization

Executing different operating system versions.

Provisioning of virtual machines can be unclear at first.

Networking could be easier.

Virtualize resources, all for one physical server to host many Virtual Machines

Provide easy disaster recovery and replication

Very very cost effective.

Scaling for large environments. No comparable solution to VMWares vCenter.

Failover of a VM to more than one host is limited.

Migrates from one host to another quite well (Live Migration)

It uses the dynamic memory efficiently

Allow to increase memory or hard drive without shutting down the vm

Be able to do all configurations thru hyper v manager even with a cluster

It provide you the use of Secondary Machine on the top of your Current Machine.

We can use our hardware more efficiently with the help of Hyper-v.

We can make development and testing more efficient.

There should we a separate security solutions for the hyper-v.

Using Hyper-V it gives laggy experience.

It should be more efficient while running hyper v on our machine.

Hyper-V is both fairly easy to learn while being robust in its capability of taking one physical server and turning it into multiple functioning systems for user consumption.

One of the gigantic strengths of Hyper-V is the fact that it is included with Windows Server.

When used in conjunction with Windows Clustering, Hyper-V goes from just being a virtualization product to also being a Disaster Recovery product. Setting up multiple hosts in a cluster, if all of them have the capability of hosting all machines at once, allows one to know that if one host goes off line the other hosts will pick up the slack and keep the virtual instances running.

Since Hyper-V is free and a MS product there is copious free support for it on the web. Most issues and questions can be dealt with just by doing some searching.

Hyper-V's snapshot feature can sometimes be a little clunky and cause issues removing the snapshots. Most problems are easily rectified but it is a weak point of the software.

Host Servers that have Hyper-V installed on them, if there are a lot of servers, becoming fairly useless when it comes to being used for other functions...both in a literal sense and licensing sense.

Despite the product being free with MS server, the new licensing scheme MS has available makes it more costly to host Hyper-V instances when one wants more than two per physical host.

Maintenance

Restores

Linux limitations

Supports a limited number of guest OS choices

Increasing the use of hardware.

Reducing operating costs with maintenance and training.

In critical applications, it is important to have a computer that can act immediately in place of the main machine, because if it stops working, all virtualized systems that run on it will also be stopped.

Overload of device resources: can affect all virtual machines.
