For these endorsed distributions, pre-configured Linux images are provided in the Azure Marketplace. All distributions running on Azure have a number of prerequisites. This article can't be comprehensive, as every distribution is different. Even if you meet all the criteria below, you may need to significantly tweak your Linux system for it to run properly.

We recommend that you start with one of the Linux on Azure Endorsed Distributions. The following articles show you how to prepare the various endorsed Linux distributions that are supported on Azure:. Azure runs on the Hyper-V hypervisor, so Linux requires certain kernel modules to run in Azure. If you have a VM that was created outside of Hyper-V, the Linux installers may not include the drivers for Hyper-V in the initial ramdisk initrd or initramfsunless the VM detects that it's running on a Hyper-V environment.

This known issue is for systems based on the upstream Red Hat distribution, and possibly others. The mechanism for rebuilding the initrd or initramfs image may vary depending on the distribution. Consult your distribution's documentation or support for the proper procedure.

Here is one example for rebuilding the initrd by using the mkinitrd utility:. If the VHD isn't aligned correctly, you may receive an error message similar to the following when you try to create an image from your VHD. If you aren't running in a Windows environment, we recommend using qemu-img to convert if needed and resize the VHD. The issue has been fixed in QEMU 2. We recommend using either qemu-img 2.

Calculate the required size of the disk image so that the virtual size is aligned to 1 MB. The following bash shell script uses qemu-img info to determine the virtual size of the disk image, and then calculates the size to the next 1 MB.

Many distributions that include a recent Linux kernel version such as 3. These drivers are constantly being updated in the upstream kernel with new fixes and features, so when possible we recommend running an endorsed distribution that includes these fixes and updates. If you're running a variant of Red Hat Enterprise Linux versions 6. Beginning with RHEL 6. If a custom kernel is required, we recommend a recent kernel version such as 3.

For distributions or vendors who maintain their own kernel, you'll need to regularly backport the LIS drivers from the upstream kernel to your custom kernel. Even if you're already running a relatively recent kernel version, we highly recommend keeping track of any upstream fixes in the LIS drivers and backport them as needed.

The tool genisoimage does work for creating video disk images, but there is no equivalent for general data. Is the Linux toolset really so deficient when it comes to optical disc tools? I've already seen this and the accepted answer simply isn't sufficient.

Seems to be the project you're looking for, linux-udf project. The project is mentioned in the Linux Kernel's udf. Looking through their sourceforge site the download is called udftools. Searching within my Fedora 19's package repository I found that exact package. Mainly these are blanking the media, formating it for use with the packet-cd device, and applying an UDF filesystem. If omitted, mkudffs automagically figures the file system size.

This requires kernel support for the packet device, and the UDF filesystem. I think you're too quickly dismissing genisoimage. If you look through the man page for it there is this switch:. To confirm that the image.

UDF support is currently in alpha status and for this reason, it is not possible to create UDF-only images. UDF data structures are currently coupled to the Joliet structures, so there are many pitfalls with the current implementation.The interactive file manager requires Javascript.

It only takes a minute to sign up. You don't say this but I get the impression you're attempting to mount the DVD drive using just your regular userid, which typically is not allowed to make use of the mount command as you're attempting to do so. To mount using mount you typically need to be root or have sudo privileges to do this:. This command should typically "just work" on most Linuxes. Occasionally you might need to do it like so:.

Trying to find an appropriate drive Thanks, I'll take a look at it on Tuesday when I'm back on site.It is also a good file system to replace FAT on removable media.

Ideally, this format should have these characteristics: Can be understood by different platforms. This makes it possible to copy files between Windows, Mac, and Unix systems. However, they have many limitations. Its specification is open.

Has rich features preferably a super set of all common file systems so information won't be lost when files are copied to this file system. Can support different kinds of physical media. Optical media is very different from hard drives. Its format should be as simple as possible. This is important when this format is implemented in embedded devices DVD player, Camcorder, Camera, etc. Complex data structures such as B-tree are not good candidates for this purpose.

Its format should evolve in a compatible way so old media can still be accessed by new systems. UDF is the only file system that meets all these standards, since it was designed for the information exchange purpose. UDF is an open standard. The design and evolution of UDF keeps compatibility in mind. It also requires platforms to preserve the information that they don't understand.

UDF is a truly universal file system. Even write-once media appears as a big overwritable floppy under UDF. Drawbacks of the current revision of UDF as of 2. Although it is not a problem for the current optical media, it may become a problem later. Does not provide a fast crash recovery mechanism. As the size of the media increases, crash recovery becomes more and more important.

Full disc scan before mount becomes less feasible on slow optical media with tens of gigabytes space. Although an implementation may use a journal to protect metadata integrity, this does not guarantee interoperability between platforms since it is not part of the standard.

As device gets bigger and bigger, compression is not that important. However, encryption may become more compelling since UDF is mainly used on removable media. Becomes more and more complex. UDF 2. File system metadata are clustered within the metadata partition so that they can be accessed quickly. Optionally, a mirror of the metadata partition could be duplicated to provide better robustness in a big cost of performance. This adds non-trivial complexity to the file system.

Does the benefit of metadata partition warrant its complexity? If the UDF implementation organizes metadata properly, it may achieve similar or better performance to what the metadata partition can provide.

Unfortunately, in UDF 2. As more and more systems implement UDF, this problem will go away. Solutions for storages.
