How to Configure QEMU with SupremeRAID RAID as a Datastore for Virtual Machines #
Environment
RAID Model: All Supreme RAID model
Host Hardware: AMD/Intel
Operating System: Linux RHEL
QEMU
Description
Virtualization has become an essential tool for modern computing, enabling multiple virtual machines (VMs) to operate on a single physical machine. QEMU, an open-source virtualization platform, is widely used to create and manage VMs across various platforms, including Linux. To ensure optimal performance of your QEMU environment, it's crucial to select a reliable and high-performance storage solution for your VMs. In this article, we will explore the process of configuring QEMU on Linux to use SupremeRAID RAID as a datastore for your virtual machines.
Resolution
Note: The IOMMU(AMD) or Vd-t (Intel) need to enable in the BIOS to enable the Virtualization
Step1: Install the Qemu KVM dependency
$ sudo yum install qemu-kvm virt-install virt-viewer
Step2: Attach VD to the virtual machine.
- Create an VD with specific size
To create a RAID-5 virtual drive with 5 NVMe SSDs:
1. Create a physical drive.
$ sudo graidctl create physical_drive /dev/nvme0-4
2. Create a drive group.
$ sudo graidctl create drive_group raid5 0-4
3. Create a virtual drive.
$ sudo graidctl create virtual_drive 0
4. Check the device path of the new virtual drive.
$ sudo graidctl list virtual_drive --dg-id=0
- Set the VD path into the kvm disk parameter
use text mode to install VM
- execute virt-install
$ sudo virt-install \ --virt-type=kvm \ --name=graid-demo-kvm \ --vcpus=16 \ --memory=102400 \ --location=/home/graid/ubuntu-20.04.3-live-server-amd64.iso \ --disk path=/dev/gvd0n1 \ --graphics none \ --extra-args='console=ttyS0'Detail parameter description:
location: the ISO's filepath
extra-args: extra configuration, the "location" parameter must be if using this parameter.
disk: the graid's vd path (/dev/gvd<#>n1)
- start to install VM
Output example:
use GUI mode via VNC to install VM
- execute virt-install
$ sudo virt-install \ --virt-type=kvm \ --name=graid-demo-kvm \ --vcpus=16 \ --memory=102400 \ --cdrom=/home/graid/ubuntu-20.04.3-live-server-amd64.iso \ --disk path=/dev/gvd0n1 \ --graphics vnc,listen=0.0.0.0,password=<your password>\Detail parameter description:
cdrom: the ISO's filepath
disk: the graid's vd path (/dev/gvd<#>n1)
- check the VNC connection port
After execute the virt-install check the VNC connection port$ virsh vncdisplay graid-demo-kvm - trun-off firewall
$ sudo systemctl stop firewalld- execute VNC to install VM
- Start using
