144 MB disk footprint
(VMware vSphere Hypervisor)

>3GB with Server Core installation

~10GB with full Windows Server installation


>1GB
OS Independence

No reliance on general purpose operating system
(VMware vSphere Hypervisor)

Relies on Windows 2008 in Parent Partition

Relies on Linux in Dom0
management Partition
Hardened Drivers

Optimized with hardware vendors

Generic Windows drivers

Generic Linux Drivers
Advanced Memory Management

Ability to reclaim unused memory, de-duplicate memory pages, compress memory pages

Only uses ballooning. No ability to de-duplicate or compress pages.

Only uses ballooning.No ability to de-duplicate or compress pages. Does not adjust memory allocation based on VM usage.
Advanced Storage Management

Lacks an integrated cluster file system, no live storage migration

system, no live storage migration, storage features support very few arrays
High I/O Scalability

Direct driver model

I/O bottleneck in parent OS

I/O bottleneck in Dom0 management OS
Host Resource Management

Network traffic shaping, per-VM resource shares, set quality of service priorities for storage and network I/O

Lacks similar capabilities

    Please dont to with HyperV if you want peace of mind. We had chosen HyperV for cost reasons and put our production systems. after which we are always scared of one issue after the other and our entire farm goes down. Microsoft has done health check and escalated to their priorty 1 engineers without any success.
    If you want go with HyperV put your non-critical and test environments

    I think better to wait till the next version is released.

    • I tried to load an ubuntu in the hyper-v, which is not supported for even testing. As stated will wait for the next version and let me see the improvements.
