ความสามารถ Windows Server 2012 Hyper-V R2 ใหม่ TechEd: What’s new in Hyper-V 2012 R2 (MDC-B330)

1. TechEd: What’s new in Hyper-V 2012 R2 (MDC-B330)
This is the f irst session of the week f ocused entirely on the new f eatures in Hyper-V 2012 R2, due out
later this year. Hyper-V in Windows Server 2012 saw monumental changes f rom prior versions, which were
needed to keep up with the competition. Hyper-V in WS 2012 R2 builds on the prior f unctionality with some
big enhancements, just a year later.
Windows Azure uses the stock Windows Server 2012 Hyper-V
Complete virtual machine compatibility between on prem Hyper-V and Azure IaaS
Hyper-V 2012 R2
Generation 2 VMs
Legacy f ree (no BIOS) but uses UEFI
Many emulated devices removed
Boots f rom virtual SCSI or synthetic network adapters
Enables UEFI secure boot standard
Supported Guest OS: 64-bit Windows 8, Windows Server 2012, 64-bit Windows 8.1, Windows Server
2012 R2
You can run Gen1 and Gen2 VMs side by side
Gen1 VMs are not going anywhere anytime soon
No perf ormance improvements on Gen2 VMs, except booting is 20% f aster and OS install is about
50% f aster.
Big advantage is booting of f a virtual SCSI or network controller instead of IDE device
Automatic Activation
Zero touch activation of VMs
Automatically activated according to the hosting environment
Gets its activation inf ormation f rom the Hyper-V host
Not tied to type of activation method (OEM, VL, etc.)
The VM does not have the product key in it
Only supported f or Windows Server 2012 R2 VMs (no prior versions)
Demos:

2. Dif f erence between generation 1 and generation 2 VMs: No ISA, no com ports, no PS/2 ports, no
f loppy, etc. Simplif ies VM hardware conf iguration.
Showed the ability to enable secure boot f or VMs
Enhanced virtual machine connection – Supports rich text copy and paste in and out of VMs. Cut and
paste f iles in and out of VMs.
VM console now supports audio redirection as well
VM connect now uses remote desktop services, so you can do smart cards, f older redirection, plus
USB support.
Full support f or these f eatures on Windows 8.1 Hyper-V, and are enabled by def ault. Disabled by
def ault on server f or security, but can easily enable per-host.
Zero-downtime upgrade
Live migrate virtual machine f rom Windows Server 2012 to Windows Server 2012 R2
Includes shared nothing live migration
More new Features
Online VHDX resize (expand, shrink, compact)
Increase or decrease the size of virtual disks while the VM is running
Live machine export (clone a running VM)
VMs with snapshots and other settings can be migrated without intervention to 2012 R2 (no more
draconian procedures)
Live migration with compression – def ault option (1/3 f aster than w/o in his demo)
Live migration using RDMA (SMB Direct) – Uses less CPU than a standard Live Migration
Faster live migration – 10Gb or less then use compression. Over 10Gb, use SMB/SMB Direct
Enhanced Linux Guest Support
Full dynamic memory support
Online backup with f ilesystem consistency (VSS-like f unctionality on Linux)
Online VHDX resize
New video driver
Linux has and will continue to run very well on Hyper-V
You can use any enterprise solution that backups up Hyper-V and get f ull Linux support automatically
Microsof t claims they of f er the most Linux support of any hypervisor, since the competition can’t do

3. VSS-like Linux backups
Microsof t releases the hypervisor integration pack with a GPL license to the open source community
Additional Features
Storage QoS
Ability to conf igure min/max IOPS on a per-VM basis
Guest Clustering with shared virtual disks. No need f or ISCSI, f ibre channel SAN, or block storage.
Can be done with SMB, or cluster in a box.
Hyper-V Replica Disaster Recovery
Extended replication (tertiary copies)
Replication f requency has 30 seconds, 5 minutes and 15 minute intervals
Example: On-prem replicated to hoster, then host replicates it elsewhere
Example: f irst hop within prem, then second hop to hoster/Azure
