Step by Step-Prepare a CentOS-Based Virtual Machine for Azure
Prerequisites CentOS Installation Notes The newer VHDX format is not supported in Azure . You can convert the disk to VHD format using Hyper-V Manager or the convert-vhd cmdlet. 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 VM for troubleshooting. LVM or RAID may be used on data disks if preferred. NUMA is not supported for larger VM sizes due to a bug in Linux kernel versions below 2.6.37. This issue primarily impacts distributions using the upstream Red Hat 2.6.32 kernel. Manual installation of the Azure Linux agent (waagent) will automatically disable NUMA in the GRUB configuration for the Linux kernel. More information about this can be found in the steps below. Do not configure a swap partition on the OS disk. The Linux agent can be configured to create a swap fi...
