The c3 and m3 instance families do provide both PV and HVM support, but AWS recommends using HVM AMIs across the board for best performance. Note: If using a PV instance of SoftNAS, DO NOT USE the /dev/sdf or /dev/sdp base device names, or you will limit the number of EBS volumes that can be attached to a maximum of 11 disks.
Amazon EC2: how to convert an existing PV AMI to HVM Any instance class should work; however, device name may be different, see notes, below I used Bionic Ubuntu 18.04 HVM AMI ID ami-0a313d6098716f372 and instance class C5.XLARGE; Attach PVM01 root partition (new volume from previous step) to new HVM01 /dev/sdf. NOTE: Older instance classes such as C3 will translate the volume name to /dev/xvdf Steps to convert UBUNTU-BASED PV instances to HVM Dec 05, 2014 AWS EC2 Virtualization 2017: Introducing Nitro Nov 29, 2017 How To Convert EC2 Instance PV To HVM Virtualization Type
A separate EC2 instance that you can use as the Site Recovery configuration server. This instance must be running Windows Server 2012 R2. Prepare Azure resources.

Currently, on EC2, PVH is not available, but PVHVM is: so the best choice for Linux (in general) would be booting a "HVM" instance with PVHVM enabled (eg, setting CONFIG_XEN_PVHVM). So below are the steps to convert the instance from PV to HVM virtualization type. Install grub on the source PV instance.(The instance which you want to upgrade). sudo yum install grub -y or sudo apt-get install grub -y; Launch a temporary Amazon Linux instance (PV or HVM) in the same region as the source PV instance.
Launch any HVM based centos. Create a volume snapshot from your PV based instance Attach the snapshot to the HVM Copy kernel and other boot files from HVM to PV snapshot volume Stop the instance Detach root disk from HVM Attach the PV snapshot to the instance as root device Launch the instance Contact me if you need help.
HVM vs. Paravirtualized - Performance Tuning HVM. The HVM virtual machine has the benefit of hardware acceleration. With hardware acceleration, the Intel or AMD chip that is running on the host hardware will intercept some of the system calls that are doing specific operations and process them in hardware, rather than in software. 7.11. Converting to Paravirtualized Guests or Installing You can continue using HVM guest, but leverage the paravirtualized I/O drivers. For more information, see Comparison of Guest Virtualisation Modes; HVM, PVM and PVHVM. Configuration, Mode Validation and Conversion to PVHVM.
