What is the role of Aki PV grub in boot process?

PV-GRUB is a paravirtual bootloader that runs a patched version of GNU GRUB 0.97. When you start an instance, PV-GRUB starts the boot process and then chain loads the kernel specified by your image’s menu.

Is AMI region specific?

When you launch an instance from an AMI, it resides in the same Region where the AMI resides. If you make changes to the source AMI and want those changes to be reflected in the AMIs in the target Regions, you must recopy the source AMI to the target Regions.

What is HVM and PV?

Linux Amazon Machine Images use one of two types of virtualization: paravirtual (PV) or hardware virtual machine (HVM). The main differences between PV and HVM AMIs are the way in which they boot and whether they can take advantage of special hardware extensions (CPU, network, and storage) for better performance.

Which instance family provides us with computer optimized instances in AWS?

Answer: C family provides us with computer optimized instances.

Which kernel is using by EC2?

To be compatible with EC2, a Linux kernel must support Xen’s pv_ops (paravirtual ops) infrastructure with XSAVE disabled or the Xen 3.0. 2 interface. The following kernels have been tested and/or have vendor support: Fedora 8-12 Xen kernels.

What does Uname mean in Linux?

unix name
uname (short for unix name) is a computer program in Unix and Unix-like computer operating systems that prints the name, version and other details about the current machine and the operating system running on it.

  8. Step 8: Find the new AMI ID.

What is HVM in AWS?

HVM (known as Hardware Virtual Machine) is the type of instance that mimics bare-metal server setup which provides better hardware isolation. With this instance type, the OS can run directly on top of the Virtual Machine without additional configuration making it to look like it is running on a real physical server.

What are the different types of instances?

The instance types can be broadly classified into five different categories as follows.

  • General Purpose.
  • Compute-Optimized.
  • Memory-Optimized.
  • Storage-Optimized.
  • Accelerated Computing.
