Red Hat/Microsoft Cross Certification Agreement

Responding to Customers' Business needs

• Customers with heterogeneous environments demand full support • Demand their vendors cooperate, irrespective of their competitive

nature

Joint support from prime OS vendors in the enterprise Agreed to cross-certify & demonstrate the commitment

• RHEL on Hyper-V

Foundational Points of the Agreement

Support from both Red Hat and Microsoft

l Customers with valid support entitlements with both

Red Hat and Microsoft can call either party for support for a certified configuration

Ł Support teams will collaborate to resolve customer

reported issues per customers' SLA agreement

 Both parties agree to resolve issues found with their

Agenda

Overview

Integration Services – What are they? Installing Integration Services

What is an IS?

IS = Integration Service

(formerly called IC – Integration Component)

ISs enable a child OS instance to run better through enlightenment

Enlightenments generally include:

ISs for Windows

Enlightenments for Windows include: Synthetic Drivers • IDE driver • SCSI driver • Network Drive • Mouse Integration • Video Integration Services

• Operating System Shutdown • Time Synchronization

• Data Exchange • Heartbeat

What do you get for Linux?

Enlightenments for Linux include (depending on version): • Synthetic Drivers

• IDE driver • SCSI driver • Network Drive

• SMP Support (one to four virtual processors supported) • Integration Services (shutdown, time sync, heartbeat) What’s Missing?

• Console Mouse Integration (can get from Xen)

The Announcement

July 2009: Microsoft

contributes driver code to Linux kernel

Submitted under GPLv2

Since, 200+ patches received from Linux community

December 2009: Linux ISs

included in the staging tree of the 2.6.32 kernel

March 2010: Linux

Linux Integration Services Functionality by

Version

Feature (deprecated)V1 V2 Staging 2.1 Beta V2.1

Date October, 2008 December, 2010 N/A March, 2010 June, 2010 VMBUS X X 2.6.33 (2.6.32+) X X

Reality Check:

ISs NOT Required for Hyper-V

Hyper-V device emulation works for nearly any operating systems (with less performance)

Key hardware components are emulated:

Video = S3 Trio64 SVGA “like” VESA Network = Intel / DEC “Tulip” 21x4x

Agenda

Overview

Integration Services – What are they? Installing Integration Services

Where To Get the ISs?

V2/V2.1 (2008 and Hyper-V R2) available from

http://www.microsoft.com/downloads

Linux kernel 2.6.32 and newer, ISs may already be there (if included by the distro - just enable)

No Integration Services package (yet) for 2.6.28+

ReadMe for Linux ISs

The “Readme” is a fantastic resource! Includes instructions for

Installing ISs

Upgrading V1 ICs to V2 / V2.1 ISs

Guidance about issues and Best Practices

(hda=noprobe hdb=noprobe) Static MAC addresses

Console Mouse Integration

Mouse work just fine, it just will not come “out of scope” automatically • Use Ctrl-Alt-Left Arrow to release mouse

• Problem with “chained RDP” – no mouse if you remote into Hyper-V host and access VM

• Use Hyper-V Console on local system instead • Remote into VM instead!

• Linux servers often loaded without GUI (don’t care about the mouse!) or accessed via remote X-Windows or VNC

• Can add mouse support after ICs via Xen site:

http://www.xen.org/download/satori.html

(code is licensed under GPL)

You also Need Linux!

The following are supported by Microsoft:

• Red Hat Enterprise Linux 5.2, 5.3, 5.4, 5.5 x86 or x64

As well as SUSE Linux Enterprise Server 10 and 11

For the latest support info, check

http://technet.microsoft.com/en-us/library/cc794868(WS.10).aspx

Must be sure to install

• Linux Source Code

ISs Install on LOTS of Linux Distributions

Microsoft DOES NOT SUPPORT other distributions, -

there’s no company on the other end of the phone to call! Other distributions may be community supported

Tip – Proxy Update

Set network proxy as per http://www.fedoraforum.org/forum/showthread.php? s=&threadid=742 Create /etc/profile.d/proxy.sh export http_proxy=http://host.com:port/ export ftp_proxy=http://host.com:port/ export no_proxy=.domain.com export HTTP_PROXY=http://host.com:port/ export FTP_PROXY=http://host.com:port/ Create /etc/profile.d/proxy.csh

setenv http_proxy http://host.com:port/ setenv ftp_proxy http://host.com:port/ setenv no_proxy .domain.com

Installing the ISs is easy,

Adding Required Components via

Command Line

Red Hat updates

yum install kernel-devel

yum groupinstall "development tools" yum update

Adding Required Components via

Command Line

After the ISO is “available”

mount /dev/cdrom /mnt mkdir /opt/linux_is cp –r /mnt/* /opt/linux_is cd /opt/linux_is make make install

Performance

The Microsoft JIL is an interoperability lab (in Cambridge Mass….right across the river!)

• Interop should not come at the cost of performance

• We have ongoing performance characterization efforts around interop initiatives like virtualization

• Performance characterization is not benchmarking! • Focused on Linux w/ Integration Services

Tested Linux VM Configs

• IO and network

experience

degradation compared

to metal

• Red Hat Certification

for emulated

http://www.redhat.com/partners/hardwarepartnes/

•IO can be ~40% faster than emulated

Migration (P2V)

Fresh install is always best, but sometimes a Physical to Virtual (P2V) migration is required

Lots of tools available - simplest way (I’ve found)

Backup and Recovery

Linux backup a challenge for Windows admins (new agents / processes)

Hyper-V can facilitate backup & recovery

DPM (or WSB, or a batch file with Xcopy) easier and almost always costs less than other enterprise backup solutions

VM can be restored to exact point in time of backup

Linux VMs backed up using parent VSS – VMs “saved” during backup

VM paused and memory saved to disk Snapshot taken on parent

Virtualization Backup

Virtualization Backup

non-VSS Aware Guest OS

For any OS or application that is not internally

VSS-aware (like Linux):

• Hibernate OS to save

memory to disk

• Snap with VSS • Resume OS
