When performing custom partitioning during the installation of RHEL 8, the specific partitions you need to create may vary depending on your system requirements and preferences. However, here are some common partitions you might consider creating:

"Root (/) partition:" This partition serves as the root file system and holds the core operating system files. It is typically assigned a significant amount of disk space.
"Swap partition:" A swap partition is used as virtual memory when the system's physical memory (RAM) is fully utilized. It is recommended to allocate swap space based on your system's RAM size (e.g., 1.5x or 2x the RAM).
"/home partition:" The /home partition is where users' home directories and personal files are stored. It can be helpful for separating user data from system files.
"/boot partition:" A separate /boot partition is optional but can be useful for situations such as encryption or when using specific boot loaders. It stores the kernel and boot-related files. The /boot partition must be at least 1GB in size.
"Other custom partitions:" Depending on your specific needs, you may create additional partitions such as /var, /tmp, or /usr. These partitions can help manage disk space allocation and separate certain system directories.
It's essential to carefully plan your partition layout based on your intended usage and requirements. It is recommended to consult the official documentation for detailed guidance on custom partitioning during RHEL 8 installation.

Click on the "+" sign and add the partitions one after another. You will be prompted to enter the mount point and size of each partition. Intalling Linux on VM -Storage partition

Make sure to choose either EXT4 or XFS as the file system for your "/boot" partition. The partition type can be set as standard, and after partitioning, it will be labeled as /dev/sda1.
The remaining file systems can be placed in a logical volume. Select the device type as LVM and the file system as XFS. Intalling Linux on VM - Storage partition
