Create and upload a Linux VHD in Azure. Note. Azure has two different deployment models for creating and working with resources Resource Manager and classic. This article covers using both models, but Microsoft recommends that most new deployments use the Resource Manager model. The Azure platform SLA applies to virtual machines running the Linux OS only when one of the endorsed distributions is used. All Linux distributions that are provided in the Azure image gallery are endorsed distributions with the required configuration. All distributions running on Azure will need to meet a number of prerequisites to have a chance to properly run on the platform. This article is by no means comprehensive as every distribution is different and it is quite possible that even if you meet all the criteria below you will still need to significantly tweak your Linux system to ensure that it properly runs on the platform. It is for this reason that we recommend that you start with one of our Linux on Azure Endorsed Distributions when possible. The following articles will guide you through how to prepare the various endorsed Linux distributions that are supported on Azure The rest of this article will focus on general guidance for running your Linux distribution on Azure.

You can convert the disk to VHD format using Hyper V Manager or the convert vhd cmdlet. If you are using Virtual. Box this means selecting Fixed size as opposed to the default dynamically allocated when creating the disk. Azure only supports generation 1 virtual machines. Bakugan Dimensions Game. You can convert a generation 1 virtual machine from VHDX to the VHD file format and from dynamically expanding to a fixed sized disk. But you cant change a virtual machines generation. For more information, see Should I create a generation 1 or 2 virtual machine in Hyper V The maximum size allowed for the VHD is 1,0. GB. When installing the Linux system it is recommended that you use standard partitions rather than LVM often the default for many installations. This will avoid LVM name conflicts with cloned VMs, particularly if an OS disk ever needs to be attached to another identical VM for troubleshooting. LVM or RAID may be used on data disks. Kernel support for mounting UDF file systems is required.

The Azure Linux agent must be able to mount the UDF file system to read its configuration and provision the VM. Linux kernel versions below 2. NUMA on Hyper V with larger VM sizes. This issue primarily impacts older distributions using the upstream Red Hat 2. Learn to create and upload an Azure virtual hard disk VHD that contains a Linux operating system. RHEL 6. 6 kernel 2. Systems running custom kernels older than 2. RHEL based kernels older than 2. For more information see Red Hat KB 4. Do not configure a swap partition on the OS disk. The Linux agent can be configured to create a swap file on the temporary resource disk. More information about this can be found in the steps below. Oracle VM VirtualBox formerly Sun VirtualBox, Sun xVM VirtualBox and Innotek VirtualBox is a free and opensource hypervisor for x86 computers currently being. METAINFMANIFEST. MFdocmanual.

Graphical Installers Are Not Supported By The Vm Ubuntu' title='Graphical Installers Are Not Supported By The Vm Ubuntu' />All of the VHDs must have sizes that are multiples of 1 MB. Installing kernel modules without Hyper VAzure runs on the Hyper V hypervisor, so Linux requires that certain kernel modules are installed in order 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 initramfs unless it detects that it is running an a Hyper V environment. When using a different virtualization system i. Virtualbox, KVM, etc. Linux image, you may need to rebuild the initrd to ensure that at least the hvvmbus and hvstorvsc kernel modules are available on the initial ramdisk. This is a known issue at least on systems based on the upstream Red Hat distribution. The mechanism for rebuilding the initrd or initramfs image may vary depending on the distribution. Please consult your distributions documentation or support for the proper procedure. Here is one example for how to rebuild the initrd using the mkinitrd utility First, back up the existing initrd image cd boot. Next, rebuild the initrd with the hvvmbus and hvstorvsc kernel modules sudo mkinitrd preloadhvstorvsc preloadhvvmbus v f initrd uname r. Resizing VHDs. VHD images on Azure must have a virtual size aligned to 1. MB. Typically, VHDs created using Hyper V should already be aligned correctly. If the VHD is not aligned correctly then you may receive an error message similar to the following when you attempt to create an image from your VHD The VHD http lt mystorageaccount. My. Linux. VM. vhd has an unsupported virtual size of 2. The size must be a whole number in MBs. To remedy this you can resize the VM using either the Hyper V Manager console or the Resize VHD Powershell cmdlet. If you are not running in a Windows environment then it is recommended to use qemu img to convert if needed and resize the VHD. Note. There is a known bug in qemu img versions 2. VHD. The issue has been fixed in QEMU 2. It is recommended to use either qemu img 2. Reference https bugs. Resizing the VHD directly using tools such as qemu img or vbox manage may result in an unbootable VHD. So it is recommended to first convert the VHD to a RAW disk image. If the VM image was already created as RAW disk image the default for some Hypervisors such as KVM then you may skip this step qemu img convert f vpc O raw My. Linux. VM. vhd My. Linux. VM. raw. Calculate the required size of the disk image to ensure that the virtual size is aligned to 1. MB. The following bash shell script can assist with this.

Many distributions that include a recent Linux kernel version i. These drivers are constantly being updated in the upstream kernel with new fixes and features, so when possible it is recommended to run an endorsed distribution that will include these fixes and updates. If you are running a variant of Red Hat Enterprise Linux versions 6. LIS drivers for Hyper V. The drivers can be found at this location. As of RHEL 6. 4 and derivatives the LIS drivers are already included with the kernel and so no additional installation packages are needed to run those systems on Azure. If a custom kernel is required, it is recommended to use a more recent kernel version i. For those distributions or vendors who maintain their own kernel, some effort will be required to regularly backport the LIS drivers from the upstream kernel to your custom kernel. Even if you are already running a relatively recent kernel version, it is highly recommended to keep track of any upstream fixes in the LIS drivers and backport those as needed.
