Creating and Managing KVM Storage Pools Effectively

~ tmolnar0831 ~ Leave a comment

Storage pools in KVM virtualization are a way to centrally manage and organize storage resources for virtual machines. A storage pool is a designated area of storage, such as a directory, partition, or network-based storage, that is set aside for use by KVM virtual machines. Once a storage pool is created and started, storage volumes can be defined within the pool and assigned to VMs.

Install and Remove KVM Guests With virt-install

~ tmolnar0831 ~ Leave a comment

virt-install is a command-line tool used to provision new virtual machines (VMs) using the libvirt hypervisor management library. It supports creating KVM, Xen, or Linux container guests and can configure various aspects such as virtual disks, network interfaces, audio devices, and physical USB or PCI devices. The installation media can be held locally or remotely on NFS, HTTP, or FTP servers.

Migrate Virtual Machines to KVM Using qemu-img

~ tmolnar0831 ~ Leave a comment

Migrating just a couple of virtual machines from other virtualization platforms to KVM is easy. Virtualbox uses the Virtual Disk Image (.vdi) format. You can clone the vdi image to a RAW image format using vboxmanage. This way you will not alter your original virtual image file. Then QEMU provides the necessary tools to convert the RAW image to the qcow2 format. Qcow2 is QEMU’s Copy On Write image format.

I Migrated to KVM+QEMU on Debian 12

~ tmolnar0831 ~ Leave a comment

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

QEMU’s system emulation provides a virtual model of a machine (CPU, memory and emulated devices) to run a guest OS. It supports a number of hypervisors (known as accelerators) as well as a JIT known as the Tiny Code Generator (TCG) capable of emulating many CPUs.

libvirt is a toolkit to manage virtualization platforms.
