 * The maximum size that's allowed for the VHD is 1,023 GB.
 * When you install the Linux operating system, we recommend that you use standard partitions rather than Logical Volume Manager (LVM), which is often the default for many installations. This practice will avoid LVM name conflicts with cloned virtual machines, particularly if you ever need to attach an operating system disk to another identical virtual machine for troubleshooting. [LVM](configure-lvm.md?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json) or [RAID](configure-raid.md?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json) may be used on data disks.
 * Kernel support for mounting Universal Disk Format (UDF) file systems is required. At first boot on Azure, the UDF-formatted media that is attached to the guest passes the provisioning configuration to the Linux virtual machine. The Azure Linux Agent must be able to mount the UDF file system to read its configuration and provision the virtual machine.
-* Versions of the Linux kernel that are earlier than 2.6.37 do not support non-uniform memory access (NUMA) on Hyper-V with larger virtual machine sizes. This issue primarily impacts older distributions that use the upstream Red Hat 2.6.32 kernel and was fixed in RHEL 6.6 (kernel-2.6.32-504). Systems that run custom kernels that are older than 2.6.37 or RHEL-based kernels that are older than 2.6.32-504 must set the `numa=off` boot parameter on the kernel command line in grub.conf. For more information, see Red Hat [KB 436883](https://access.redhat.com/solutions/436883).
 * Do not configure a swap partition on the operating system 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 following steps.
 * All VHDs on Azure must have a virtual size aligned to 1MB. When converting from a raw disk to VHD you must ensure that the raw disk size is a multiple of 1MB before conversion. More details can be found in the steps below. See also [Linux Installation Notes](create-upload-generic.md#general-linux-installation-notes) for more information.

     Graphical and quiet boot are not useful in a cloud environment where we want all the logs to be sent to the serial port.  You can leave the `crashkernel` option configured if desired. Note that this parameter reduces the amount of available memory in the virtual machine by 128 MB or more. This configuration might be problematic on smaller virtual machine sizes.
