Virtualization of MAC 10.4 in MAC 10.6 OS

Hi,
I am senthil, working as Technical support helpdesk in Accenture Services pvt ltd. Here we have Apple 10.4, 10.5 & 10.6 version of OS in our organization.
Pls provide me the answers for the below queries,
1. Can we create a virtual instance of 10.4 version in any other higher ver like 10.5 or 6 MAC mini?
2. Is there any MAC recommended software available for virtualization like VMWare in Windows?

Welcome to Apple Discussions!
Best to find some hardware that will run 10.4, 10.5, and 10.6. Any Mac that predates October 26, 2007 will do that, except those that do will not run Classic. For Classic needs, you'll want Macs that came from prior January 6, 2006. As long as the Mac is 867 Mhz or higher it will support 10.4, 10.5, and Classic. Read my FAQ* on what limitations you may experience, and the one following how to obtain an older Mac:

P.S. MAC is an acronym for Media Access Control. Mac is the nickname for Macintosh, the operating system and the hardware of Apple Inc's highly successful desktop and notebook computers. When referring to the company, call them Apple or Apple Inc. When referring to the computers, call them Mac, Macs, or Macintosh, and when referring to the operating system, refer to Mac OS.

Enable Hardware Virtualization On Mac Pro 8 Core (Early 2008)

Hi,
Has anyone has any success enabling the Intel VT-X feature on the Xeons on the Mac Pro (Early 2008, 8 core Xeon)? The VMWare ISO indicates that its turned off on all cores, and NOT locked. VMWare confirms that its not enabled, by not allowing me to boot a 64bit guest OS.
Has anyone had any success? ive got the latest EFI BIOS, hoping that it would fix it (like a BIOS upgrade did aparently for the Mac Mini).
As the feature bit is not locked, maybe there is a way of doing it in software (normally the BIOS turns the feature on or off, then locks it, the lock holding until the next cold boot). We would need ring0 access to the processor.
Alternatively, there is a EFI exe floating around that aparently enabled it for the Mac Mini (on old firmware with the bug).
Whats the best way to report this to Apple? do they have a history of fixing user-reported issues?
Thanks
George

Interestng about firmware. Sounds odd to have cpu from different batches.
link to the thread w/o the session ID.

One security expert uses a Mac Pro and runs multiple VMs was interviewed and up on Tom's Hardware - there have been changes since 2006 (1st gen Mac Pro) compared to even 2008. Probably nothing to help but VT -d and other stuff was news to me.

Understanding Wireless Mac Address

Hi,
I would like to know te range of mac address used for only Cisco Wireless, and I would appreciate to know how the ap and the controler assign the virtual mac address they use and how to get them from the WLC gui.
WLC - 4400
AP - Air1131
Thanks

As you add SSIDs (Service Set Identification(s)) to an access point each BSSID (Basic Service Set Identifier) receives a virtual mac address. This allows for wireless network segmentation as well as for wireless clients to communicate via LAYER 2 with each access point BSSID.
A Cisco access point takes the base radio mac address and then virtualizes the mac address as additional SSIDs are added. What is interesting is how the virtual MAC addresses are selected. Pay very close attention to the 2.4GHz and 5 GHz radios and BSSIDs.
BASE RADIO MAC ADDRESS
You can find the base radio mac address under WIRELESS->Select Access Point
Virtualized BSSID(s)
I configured a controller with 16 SSIDs. Each SSID named as 01,02,03,04,05,06, 07,08,09,10,11,12,13,14,15 and 16. I then enabled both the 2.4 GHz and 5 GHz radios. Cisco WLC access points have a limit of 16 SSIDs on each radio.
I then fired up AirMagnet WiFi Analyzer Pro to conduct a capture.
Note: The access point base radio mac address ends in A9:10.
2.4 GHz – Notice the first SSID ‘01’ is assigned the BASE RADIO MAC ADDRESS A9:10. The second SSID is appended with a .11 and so on.
5GHz – Notice the sixteenth SSID ‘16’ is assigned the BASE RADIO MAC ADDRESS A9:10. The fifteenth SSID is appended with a .11 and so on.
NOTE: The VIRTUAL MAC ADDRESSES get reused by the access point on both the 2.4GHz and the 5GHz radios.
Virtualized BSSID Assignment
Keep in mind, the assignment or order in which the virtual mac addresses are assigned in the above example has nothing to do with the WLAN IDs that are configured in the WLC. Rather, the virtual mac addresses are assigned in order by how the SSID is assigned to the access point.

Mac Pro, Windows 7 Virtual PC-XP Mode Problem w/ Hardware Virtualization

I have installed windows 7 (64 bit) on an 8 month old intel mac pro with latest bootcamp. runs great. cannot get virtual pc / xp mode to work.
confirmed latest firmware, confirmed processor has virtualization (vmx listed in processor details when boot to snow leopard).
when i run ms hardware-assisted virtualization detection tool it confirms hardware virtualization. after i install xp mode and virtual pc update i get an error message that there is no virtualization. ms hardware-assisted virtualization detection tool will now also report no virtualization. if i uninstall xp mode and virtual pc update, ms hardware-assisted virtualization detection tool will again confirm virtualization.
any thoughts? i searched forum but did not see anything - sorry if i missed it.
thanks in advance for input...

Because the hardware of Mac Pro does have Intel-VT capability, it's just disabled.
One solution (though a very lame one) is boot into OS X first, run VMware Fusion or Parallel (which enables Intel-VT), then restart into Windows.
Just hope there would be some way to enable Intel-VT on Windows...

How can I virtualize Lion if I bought a new Mac with Lion preinstalled?

Hi folks. I read that you were allowed to virtualize 1 instance of Lion after purchasing Lion. How can I virtualize Lion if I don't have any install media with one of the new macs?

If you bought on of the new MacBook Airs or Mac Minis, you will have a short term problem as the you will not be able to download a fresh copy of the Installer. See my post here.
This problem should go away soon probably with 10.7.1
If onthe other hand you bought one of the oleder models and it came with Lion, then you can download another copy of the installer by:
Open the App store.
Hold down the option key while selecting "purchased"
Lion should now say "Install" rather than "Installed".
Click install to download a new copy of the Installer.
As soona s th installer automoatically opens after doqnloading, quit it
Save a copy of the installer from Applications.

Intel Virtualization disabled on my Mac Mini?

We've successfully installed and run Parallels Desktop for Mac on two MacBooks and a MacBook Pro in order to run Windows XP Professional virtual machines.
On my Mac Mini, however, when I set up a virtual machine and am installing the guest OS from a Windows XP Pro installer CD, I get the following message from Parallels Desktop:
"Your CPU supports Intel Virtualization Technology (VT-x) but it is currently disabled (locked by firmware). Virtual machine will be started without VT-x support (in software virtualization mode)."
Has anyone seen this message before? Is there some reason why VT-x would be turned off on my Mini and not on our other machines? Is it easy to turn on? I couldn't find a reference anywhere.
Here are my specifics:
o Mac Mini, 1.66GHz Intel Core Duo, 512MB RAM (to be expanded soon)
o Host OSX: Up-to-date 10.4.7
o VM Settings: Typical + 512MB RAM & 6GB virtual disk
o Guest OS: Being installed from Windows XP Pro CD
-- Thx in advance for any help.

This is a known issue; if you search the Parallels support boards, you'll see what I mean. It appears that a number of units shipped with VT-x turned off, while many other units shipped with it on. It is turned on in my unit, though I'm not sure if it was shipped that way, or if it was enabled when I updated the firmware. If you haven't already downloaded the update and installed it, I'd try that first.

Mac Pro as a VMware virtualization workstation

Hello all,
I've used my Mac Pro quite heavily for virtualization-related tasks, from running a couple of Windows (XP and 7) VMs for various apps I need to support on both platforms. My virtualization needs are taking a steep increase. While I'd love a beautiful 12-core monster, can't afford that...yet :-(. Thinking instead about maxing this one out. The CPUs are as good as possible I believe, Xeon X5365'[email protected] x8. Want to upgrade RAM from 12GB to 32GB, add an Apple RAID card (unless someone has a better suggestion?), 4x Seagate Constellation 2TB SAS drives in RAID-0 (I want maximum performance possible, multiple VMs, 12-14 at once, will cause very high I/O usage, capacity and performance are most important to me), I'll backup necessary stuff external via iSCSI SAN. Does anyone have a better plan for achieving max performance from this workhorse? Any opinions welcomed! Thanks.

Whoa! That sounds like it could be incredibly expensive! Let's start with the easy stuff! Activity Monitor and the Windows Task Manager inside the virtual machines can inform you of RAM usage and help you decide if that's the better first step. If you're maxing out your RAM usage within the VMs, they will start using the hard drive(s) as RAM. That's incredibly slow, because hard drives are a lot slower than RAM. You should also check the settings for RAM allocation for your individual VMs using your virtualization client (VMWare) to make sure they can access as much RAM as the system will comfortably allow. 12 VMs running simultaneously on 12 GB of RAM means that each system will be allowed less than 1 GB. That's not much for Windows 7. You also need to remember that your host OS needs RAM, too. If your RAM allocation settings are less than ideal, adjusting them can provide a tremendous gain in performance for FREE!
I predict RAM will be of greatest benefit to you, and it's cheap, so it's a good place to start. Increasing your RAM alone might give you the performance edge you want without a storage upgrade. Do keep in mind that adding additional RAM to the system will require you to revisit those allocation settings to make any difference in performance of the VMs (assuming they hit their memory ceilings, which seems quite likely). If you have 32 GB, 14 VMs can use over 2 GB simultaneously and leave plenty of room for the host OS.
As far as storage goes, I'm hearing that the Apple RAID cards are over-priced and the fact that they are internal could make things far more difficult for you. I'd recommend trying SSD, but the cost/benefit of that will depend on your budget and spatial requirements of your VMs. I'm also not sure if they can match the reliability of the server-grade rotating storage you have in mind, but theoretically, neither can the hard drive(s) you already have in the machine.
I'd also check out an external solution rather than an internal one:
http://eshop.macsales.com/MyOWC/Upgrades.cfm?sort=pop&model=264&type=Hard+Drive+ Controller
There are many different options for hard drive controllers and you can read reviews for nearly all of them. They're not all equal and there is something different for every budget.
External storage is probably the best solution for you because it maintains the functionality of the internal drives you already have while you migrate to the new system. In the future, you could continue to use those drives for archival and backup. Of course, you could always simply migrate a portion of the VMs outside the machine into the external system and use both internal and external systems simultaneously. When you decide to upgrade the computer, you'll be able to move the card and enclosure to a new machine more easily.
REMEMBER: If you're running a bunch of VMs with high demand for disk I/O, spreading the load over a greater number of hard drives can reduce the queue length for each individual drive and reduce latency. Try using different disks for different VMs.
This my plan of attack for you:
optimize your RAM allocations
check your performance
upgrade your RAM
optimize your RAM allocations again
check your performance
run heavy operations and check disk usage in Activity Monitor
if disk usage in Activity Monitor stays pegged at max of drive capability and you have available drive bays, add an aditional internal hard drive, or two, or three.
migrate some of the VMs to the new hard drive(s) and run them from their new locations to test performance again
if you're still not happy, consider RAID and have yourself a good cry when you see the price-tag
I predict you'll be overjoyed by the time you reach step 5. Just keep in mind, hard drives fail! Redundancy is important and off-site backup can be a life-saver in case of disaster.
Let me know if this helps! Don't forget, mark this reply as helpful if it helped or correct if I nailed it.

Which mac operating systems am I allowed to virtualize?

which mac operating systems am I allowed to virtualize? I would like to create an exact replica of a client's setup. (Mac OS X Snow Leopard server) on my Mac for some tweaking.
I am aware this is the Lion forum. Lion appears to be easier to virtualize, which is why I'm asking it here.
Can I then deploy from a virtual machine to a production environment? Is VMWare or Parallels better for this?
Thanks.
--Sam

My understanding is the only thing you maybe allowed to virtualize is a Server OS.
With lion Server is more of an app so im not sure how that works into their licenseing.

Virtualization on a Mac Pro

Hi,
I am looking at the options of using virtualization on a 8 core Mac Pro. Instead of the solutions like VMWare Fusion I would like to create several virtual machines running independently in the background (database server, webserver, etc) and manage the resources used by each Virtual machine seperately. In the PC world there are several option (like vmware esx or xen) but what are good and supported options for use on a Mac?

I know I've seen threads of someone using Windows 2008 Server (the RC is available for free download) and running their VMs under that.
Maybe something in these: Discussion threads "VT"
The Mac Pro is a great home server machine - twin quad core Xeons, plenty of memory capability, and very quiet. The problem is that by default, Apple doesnt enable the intel VT-X extensions, which are needed to get KVM working.

Virtualization support is disabled on your Mac

Installed new OS and now Pararells 8 will not open Windows 7 I get a message that "virtualization support is disabled on your Mac". Pararells 8 worked great before I installed the new OS. Have tried uninstalling and reinstalling Pararells 8 with the update, but still can't get into Windows 7

What kind of desktop virtualization software doesn Mac OS support?

Hi all,
I was a Windows/Linux user and have been working with VMware workstation for a long time for desktop virtualization. Now I'm moving on to the Mac OS and would like to to the likewise virtualization software supported by Mac OS, so that I can run Windows/Linux virtual machine on Mac.
Thank you!

Does virtualization virtual box work for mac os 10.7 Leopold/ lion & windo

I am grateful to my google search using "how to run windows-7 bootcamp in virtualbox" . After spending hours of trial & error on Apple, VirtualBox, Youtube & other forums by chance I hit correct words and first in the search list was most useful. It gave simpler and easier instructions than others. Guidance is in easy steps and it works great.

Virtualization disabled on Mac Pro?

This may have been addressed before, but can anyone else confirm that the Mac Pros, when running Parallels, give a message stating that Virtualization technology is disabled, and that putting the machine to sleep and re-awakening it might fix the problem?
Apparently this is an issue with Apple's firmware, according to the Parallels website, and I have indeed tried the sleep "fix", which seems to work.
Not a huge issue, since performance under Parallels is quite acceptable. With luck Apple will have the fix out sometime soon.
PS I did install the EFI update; evidently the fix wasn't in there.

Yes, the Mac Pros require an at-yet-to-appear firmware update to resolve the Virtualization bug.
In the meantime, if you start Parallels (but not the VM), put your machine to sleep, then wake it up and start the VM, it will be enabled. One of the odder aspects of the bug is that starting from a cold boot will disable it but waking from sleep will enable it.

Mac Mini OS LION paralleldesktop Virtualization

Since the upgrade of my Mac Mini to OS Lion when i want to launch Windows under Parallels desktop 6, i got the message that virtualization is not active please activate it. When i click OK i got the second message -load driver of parallels desktop is not possible- Please reactivate your Mac and try again.
BUT
How to reactivate the Mac?
and where to activate virtualization ...as BIOS on PC Intel i know that Bios is called EFi on Mac but how to access to the EFI
Thank You
Best regards
User from France

First, be sure you are running the most recent version of Parallels 6. Second, report problems with Parallels to their tech support site.

I have a mac running windows... no bootcamp or any other virtualization program... how can i go back to mac os?

A friend of mine played this cruel prank to me... he erased everything on my mac and installed windows 7 on it... at least he backed up my data... but whatever i just want to go back to mac and i've tryed everything and it doesnt work... please help!

Shootist007's advice relies on several assumptions. In order for that to work, you would need to have a recent Mac with Lion installed, or a somewhat recent Mac with Lion and the latest firmware update installed.
Also, there's probably an easier way. How did your "friend" (whose a** deserves a good kicking) back up your data? If he used Time Machine to back up the entire system, you can simply erase the hard drive and restore that system. See:
http://pondini.org/TM/14.html
If he made a "clone" of your old system, simply boot from the clone, erase your internal hard drive and clone everything back, using a tool like Carbon Copy Cloner or SuperDuper.
If reinstalling the system is necessary and you're not using Lion, you'll want to boot from your Mac OS X install disk by inserting it and restarting, then holding down the 'c' key until the Apple logo appears.
Edit: Oh, and you should start making your own backups. If you don't have any backups of your own, it's entirely possible that your "friend's" stunt could have destroyed valuable data. What happens if the drive he backed up to wasn't much good and fails before you get the data restored? You need to have a minimum of two complete, separate backups.
