How to create a virtual disc drive?

I need to get my computer to treat an ISO image as if it's a physical optical drive. I've tried mounting it via loop devices, which is very useful, but it's not enough (basically, I need programs to be able to find it as a device, not a mounted filesystem). Any ideas?

You could create an empty file with dd like this:
dd if=/dev/zero of=disk-image count=40960
That will create a 20 MB file
Then you can format it with a file system:
/sbin/mkfs -t ext3 -q disk-image
Tell it to proceed even if it is not a block specific device.
Mount it and you have a virtual disc drive.
mount -o loop disk-image fs
I borrowed this from here:

How to create a virtual drive of a non bootable drive ?

How to create a virtual drive of a non bootable drive ?
through which we can see the preview of the drive without clicking on the original drive.

Alias can never be mount, but the virtual drive I want to create must be able to mount and unmount.
Desktop having both original and virtual drive.
My system is booted from 'Snow leopard' and I've an another drive, name 'Disk Testing' so by using a software I create the virtual drivre of 'Disk Testing' as you can see in the image. Both the drives are identical to each other and both are able to mount and unmount, they are having same data and attributes.
So I want to create exactly this kind of virtual drive by using any apple script or command.i.e without using any software.

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
The system I'm have is a Mac-mini that had SL on it and no SuperDrive. I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
Step 2
After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
Step 3
After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

How to create local virtual web host ex. myserver.local?

Hi
I'm sorry but following steps in Yosemite Server help led me to nowhere.
Could you please explain how to create local virtual web host ex. myserver.local?
Thanks

Hi Sergey,
I assume that you mean virtual desktop storage location, which I don’t think that we can change this setting for an existing collection.
You can create a new collection, during the creation process, you will be able to select a different storage location for new VMs.

How to create a bootable thumb drive for OSx 10.7 ?

Greetings - This is my first system install without using a DVD. I've seen caveats re: making a bootable thumb drive to avoid future problems. Please refer me to an Apple document that explains how to create such a bootable thumb drive from the downloaded disc image. Thanks!

Most users create an image when they have multiple installs. You can simply drag the Install Mac OS X Lion installer from Applications to another drive or folder on your computer. Apple removes the installer after it runs.
You can always download again from Purchases in the Mac App Store (MAS).

How to create a Virtual provider in BI 7.0?

Hi friends!
I need create a virtualprovider (with SCM source system), but I find the option 'Create Virtual Provider' in the context menu only when the infosource is 3.x
How can I do it in 7.x?
Thanks in advance!
Edited by: SSap on Oct 28, 2009 9:11 PM

1.How can I do it in 7.x?
In BI7, just right click on any infoarea, and choose create 'virtual provider'. For direct access, you choose Virtual Provider with 'direct access'. There's an option to use the old R/3 infosource. What this means is that you can create an infosource with transfer rules and such, and when you create the virtual infoprovider, it will use the structure in the infosource automatically and the flow of data is automatically link R/3 with the transfer rules and the virtual infoprovider. Note that no update rules exist with this kind of setup.
In BI7 you have a more flexible approach in that you can create a transformation to configure the 'transfer logic' of your virtual infoprovideralong with start routine, end routine or any other transformation technique visible with using a transformation rule.
But using BI7 setup, you need to create a sort of 'pseudo' DTP, which doesn't actually do anything, meaning you do not 'execute' it to start a data transfer.
After all is done, you need to right click on the virtual infoprovider and choose 'Activate Direct Access'. If you use Infosource, go to the Infosource tab, and choose the infosource. If you're using BI7 setup, choose the DTP related to the transformation and save it.
a virtual infoprovider with direct access is really slow if you have a lot of records transmitting between the remote function calls.
Hope this helps

How to create bootable USB thumb drive from Lion on Mac Mini 2011?

Hello folks
Yesterday my new Mac Mini (Core i7 2,7 Ghz, 4 GB RAM, ATI Radeon HD6630M 256 MB) arrived. It replaces my old Mac Mini (Core Duo 1,83 Ghz, 2 GB RAM, Intel GMA950 64 MB). One day I'll replace the 500 GB 5400 RPM HDD in this Mini by an Intel SSD drive (just like I did with my previous Mini). I'll do a fully clean install then (formatting the SSD drive in Disk Utility and then installing Lion on it from a bootable USB thumb drive). The only problem is I can't seem to download Lion for free from the Mac AppStore (MAS) although I have bought a new Mac Mini which came with Lion pre-installed. I know how to create a bootable USB thumb drive with Lion on it when you download it from the MAS. But that's the problem... I can't seem to download Lion from the MAS for free. When I open the MAS while holding down the Option key I can download Lion but it will charge me for it. Is there any way I can download Lion from the MAS without paying for it? Since it already came with my new Mac Mini 2011 this should be possible I guess?
And will I still be able to download the iLife '11 apps (iPhoto, iMovie and Garageband) for FREE that came with my new Mac Mini when I do a fully clean install as described above? Thanks in advance.
Greetings
Jocau

After doing some research, it seems that there are only 2 WAYS to do a complete reinstall of Lion on the Mac Mini 2011 without paying for the Lion download in the Mac AppStore (i.e. recreating every partition, also the Recovery HD partition, from scratch e.g. when installing Lion on a clean HDD/SSD).
1) COMPLETELY clone the Mac Mini 2011 HDD including all of its partitions to an external drive and restore it when you want to do a complete reinstall.
2) Use the LION INTERNET RECOVERY feature built-in into new Macs that ship with Lion (this feature is present in new Macs starting from the Mac Mini 2011 and Macbook Air 2011).
OS X Lion: About Lion Recovery
Lion Internet Recovery
If you happen to encounter a situation in which you cannot start from the Recovery HD, such as your hard drive stopped responding or you installed a new hard drive without Mac OS X installed, new Mac models introduced after public availability of OS X Lion automatically use the Lion Internet Recovery feature if the Recovery HD (Command-R method above) doesn't work. Lion Internet Recovery lets you start your Mac directly from Apple's Servers. The system runs a quick test of your memory and hard drive to ensure there are no hardware issues.
Lion Internet Recovery presents a limited interface at first, with only the ability to select your preferred Wi-Fi network and, if needed, enter the WPA passphrase. Next, Lion Internet Recovery will download and start from a Recovery HD image. From there, you are offered all the same utilities and functions described above.
As with the Recovery HD, reinstallation of OS X Lion from Lion Internet Recovery requires an Internet connection. See "Supported network configurations and protocols" below.
Restoring iLife applications after Internet Restore of OS X Lion
If you reinstall Lion on a new Mac that shipped with OS X Lion installed, on an erased or replaced hard drive, you can download iPhoto, iMovie, and GarageBand from the Mac App Store.
After installation, start from Lion.
Double-click the App Store icon in the dock.
Enter your Apple ID and password.
Click Purchases.
If you haven't previously accepted your bundled iLife applications within the Mac App Store, you should see your iLife applications appear in the Accept portion of the screen. Click Accept.
You may be asked for your Apple ID and password once again. Your iLife applications now move to the Purchased section. These applications are part of the software that came with your Lion based computer. Your account will not be charged for them. Click Install to compete installation of your applications.
Source: Lion Recovery
It's a bit sad that these seem to be the only 2 options. Lion Internet Recovery is the preferred one here since my monthly internet traffic limit isn't a problem (but my download speed is). This problem could have been easily solved by Apple by just checking the system specs or serial number when trying to download Lion from the Mac AppStore. By using one of the 2 options in my previous sentence the Mac AppStore could see that I have a new Mac Mini 2011 that ships with Lion which would give me the option to download Lion from the Mac AppStore for free and eventually create a bootable USB thumb drive of it.
