Broadcom to acquire VMware for 53 billion euros – IT Pro – News

From the moment you start seriously with hypervisors, Hyper-V quickly falls through the basket. If you want to cluster and you want to use the local storage, you are obliged to take data center licenses because you need storage space immediately.

There comes the problem that you do have fail-over options where the VM can live migrate or reboot on another node, but the shadow option on VmWare is nowhere to be found on Hyper-V, essentially you can’t guarantee a VM live (no reboot) in Hyper-V on a cluster. You also have little control to send different tasks over different networks, both your storage, cluster communication, fail-over, it all uses the same network.

Another problem is if you want to assign hardware directly, in Hyper-V that means you can forget about fail-over, VmWare can handle that through assignable hardware.

Another problem in Hyper-V is that you can only map VHDX files via a virtual SCSI controller, which gives way too much latency if you have NVMe drives or worse if you have persistent memory. VmWare does have virtual NVMe controllers.

Hyper-V is nice as a single node, easy to use too. But then you are comparing with VmWare Workstation and not with ESXi.

When you start clustering, the user-friendliness of Hyper-V melts like snow in the sun. Storage spaces direct is anything but user-friendly to set up, you suddenly have to manage clustered VMs in a different management tool, you have to keep managing each node separately and I’ve already lost count of how many times it refuses to transfer a VM shooting, from certificates to open the virtual TPM (you have to manually export and import) to numa nodes that don’t match (my biggest problem with this is that you don’t get a notification beforehand, you only find out when you actually want to overshoot to another node, preferably with a cryptic message such as not enough resources available)

If you put Hyper-V next to ESXi instead of Workstation, Hyper-V still has a long way to go. ESXi does have one major disadvantage, the moment you actually want to use those nice clustering options and high availability, then they know very well at VmWare that they are on a completely different level there, which is seriously calculated in the price.
