Авторский учебный курс от Архитектора Microsoft Алексея Кибкало.
Поколения виртуальных машин
Автоматическая активация ОС в виртуальных машинах
Что такое Live Migration. Скорость работы, компрессия, миграция с WS2012 на WS2012R2
Живое изменение размера дисков виртуальных машин
Storage QoS, контроль и мониторинг производительности дисковых ресурсов
Клонирование и экспорт запущенных ВМ, экспорт снимков ВМ
Новые возможности в виртуальных машинах с Linux
Дисковая дедупликация для работающий VDI машин, дедупликация CSV
При поддержке "Звезды и С" www.stars-s.ru
1. Новые возможности Hyper-V WS 2012 R2

2. Virtual Machine Generations
Generation 1 and 2 VMs
Generation 1 – no changes
Generation 2
No Legacy devices
UEFI Based, no emulation
Boot from SCSI
Support for Secure Boot (no virtual TPM)
Only x64 versions of WS2012/Win8 and later
Not supported by VMM R2 yet (pre Beta)
Fast boot (really fast)

7. VMConnect and Enhanced mode
6 Учебный центр "Звезды и С" www.stars-s.ru
Full RDP Stack inside
Copy/paste (files, clipboard)
Better video
Sound
High resolution
Two factor authentication
Full capabilities, even when network is down
Enable per server, configure per user
Works for both Gen1 and Gen2, just 2012R2 and 8.1 guests
Switch back to basic mode when needed
Select resolution and redirected devices for enhanced
session, save settings per VM
12. Automatic Activation
Учебный центр "Звезды и С" www.stars-s.ru11
VMs activate automatically according to the hosting
environment (only for Datacenter SKU)
Guest VM is automatically licensed (OEM, Retail, VL) if host
is activated. No entering keys
Zero touch for hosters
13. Live Migrations enhancements
LM from WS2012 to WS2012 (over four 1Gbps interfaces
teamed) for a WS2012 VM (6GB static) takes 107 seconds
LM from WS2012 to WS2012R2 - Live! One direction (no
back). Need to enable cross-version saved states and
snapshots on SERVER host OS takes 93 seconds
LM from WS2012R2 to WS2012R2 with compression
(configurable, enabled by default, does only if there are
free CPU cycles) takes 13 seconds
LM from WS2012R2 to WS2012R2 with RDMA (doesn't use
CPU or extra network resources, uses PCI bus - make sure
to have PCI3, when you have more them 3 RDMA cards,
you are limited by memory speed) takes 6 seconds

14. Live resize of the VM disks
Takes moments
Supported for VHDX only
For Gen1 - can't be boot drive (SCSI)
For Gen2 - any disk
Increase and decrease
Any OS in VM

16. Storage metering and QoS
Storage IO restriction and storage IO metering
Live changes for running VM
Учебный центр "Звезды и С" www.stars-s.ru15
17. Virtual disk sharing
Share virtual disk (VHDX file) between any number of VMs
VMs must be offline to add shared disk
Disk is presented as SAS device
Учебный центр "Звезды и С" www.stars-s.ru16
18. Export/Cloning
Copy a running VM (create a clone of running VM in VMM,
only when VM runs on 2012R2 host)
Export running VM
Export a snapshot of a running VM
Учебный центр "Звезды и С" www.stars-s.ru17
19. Changes for Linux guests
Dynamic memory for Linux VMs
Online backup of Linux VMs with Windows Server Backup,
DPM, etc (when we do a VSS snapshot on host, we ask VM
to do a temporary filesystem freeze)
Учебный центр "Звезды и С" www.stars-s.ru18
20. Network Virtualization
Is now a part of switch (not a filter)
Automatically enabled for all adapters in vSwitch
Gets Consumer Addresses from VMs
Test-NetConnection for diagnostics
Учебный центр "Звезды и С" www.stars-s.ru19
21. RemoteFX updates
Media streaming: up to 50% less bandwidth then WS2012
Lower bandwidth and CPU utilization for adaptive graphics
DirectX 11.1 support for vGPU
Учебный центр "Звезды и С" www.stars-s.ru20
22. Hyper-V Replica
Top feature of Hyper-V in WS2012
Allow replication frequency changes (30 sec, 5 min, 15
min). 5 minutes is still default
Учебный центр "Звезды и С" www.stars-s.ru21
23. Hyper-V Replica extension
Allow extend replication from secondary replica to a third
server (have a fast onsite copy and slow offsite) (hosters
who are DRaaS want to protect secondary replicas to
achieve SLAs)
Replicate to Azure VM Role (with VMM)
Учебный центр "Звезды и С" www.stars-s.ru22
24. Disk deduplication
Supports VDI (and just VDI) running machines
Supports shared disks, including CSV
No support for bootable volumes, or ReFS
