Virtualizing Linux and FreeBSD on Windows Server v.NextJason M. AndersonTudor DamianCDP-B233

Customers can easily manage and extend their Linux and FreeBSD workloads.

Goals for Linux & FreeBSD Support

Provide the best experience for running Linux and FreeBSD on Hyper-V and in Microsoft Azure.

Customers have great choice and availability in running Linux and FreeBSD distributions.

How Operating Systems Run on Hyper-V

Yes Yes

No No

Emulated Devices• No Hyper-V

Synthetic Devices• Full Hyper-V

Integration Services OverviewHyper-V presents synthetic devices to the guest OS

Synthetic devices seen by the guest OS are the same, regardless of the real hardware under Hyper-V

Windows Server Host

Windows Server Hyper-V

Linux FreeBSD Windows

Integration Services Overview

Windows Server Host

Windows Server Hyper-V

Linux FreeBSD Windows

Guest OS needs drivers for these synthetic devices

Just like an OS needs drivers for devices it sees when running on real hardware

Integration Services Overview

Windows Server Host

Windows Server Hyper-V

Linux FreeBSD Windows

Integration Services == the drivers for the Hyper-V synthetic devices

They run in the guest OS so must follow the device driver model for that guest OSAlso include some user-space daemons that interact with the drivers

Targeted Linux distributions for LIS packages

Linux Server distributions (applying on DT versions may work, not supported)Only for distros that do not have LIS built-in (upstreamed)

Can’t install newer LIS packages on top of distros with LIS built-inData driven (customer demand, market needs)

Linux Integration Services PackagePlanning principles

New feature availability that have been upstreamed into newer kernelsMaintain compatibility with targeted kernel versions (can’t introduce features that will not work on older kernelsMeans some LIS packages may not have the same features upstreamed

Data driven (customer demand, market needs)

New LIS Features - UpstreamedHyper-V Version Feature Description Upstream

2008 R2 +TCP Offloading Transfers some of the workload from the CPU to a network adapter

during network data transfers. Spring 2014

2D video driver Provides enhanced graphics performance and superior resolution for Linux desktop users. 2013

2012 +Dynamic Memory – Hot add Dynamically increase the amount of memory that is available to a

live virtual machine. Spring 2013

vRSS Virtual Receive-Side Scaling spreads the load from a virtual network adapter across multiple virtual processors in a virtual machine. Spring 2014

2012 R2 +

Generation 2 VM Support Allows Linux virtual machines to be run in UEFI enabled Generation 2 mode.

Spring 2014File Copy from Host to Guest

Allows copying of files from host to guest without using the network interface.

TRIM supportAllows Linux virtual machines to optimize storage consumption through technologies such as Thin Provisioning. Particularly useful for Linux virtual machines hosted in Azure.

Fall 2013

Online VHDX resize Allows expansion of live mounted fixed sized Linux VHDs.

Spring 2013Virtual fibre channel Allows Linux virtual machines to natively access high speed fibre channel networks.

Online backup Facilitates zero down time backup of live virtual machines to Azure.

LIS Features “In Progress”Hyper-V Version Feature Description Status

2008 R2 +Enhanced Time Synchronization

Avoids clock drift issue by ensuring VM's time is kept synchronized with the maintained time on the host using host time sample.

Upstreaming

Network Performance Improvements

New offloads and network optimizations to improve performance for 10Gbps and above network cards. In Progress

2012 + SR-IOVMaximizes network throughput while minimizing network latency as well as the CPU overhead required for processing network traffic.

Kicking Off

Windows Server v.Next

Secure BootEnables secure boot feature for Linux VMs using UEFI which has the boot loader signed with a Microsoft key as the root of trust. Windows

Server v.NextHot Add/Remove Synthetic NIC

Manually add/remove virtual NICs when the VM is running.

Azure Infiniband Infiniband driver for Linux guests supports high performance computing running on Azure version of Hyper-V.  

Azure v.Next

DEMO

Secure BootHot Add/Remove NIC

Helps prevent unauthorized firmware, operating systems, or UEFI drivers from running at boot time. With Windows Server v.Next, Linux VMs with a signed boot loader will have the option to leverage secure boot.

Canonical and SUSE signed their boot loaders with the Microsoft UEFI CA. Enabled by default for generation 2 virtual machines.Set Certificate through power shell.

Secure Boot

Eliminating workload downtime due to reconfiguration
