The identifier "pavmkvm801qcow2" can be broken down to understand its function: pavmkvm801qcow2 new
Create a new .qcow2 image named pavmkvm801.qcow2 and set up a KVM virtual machine with it.

Before booting the image, place it in the secure default storage pool of your hypervisor and inspect its parameters:
The format is the standard storage backbone for modern Linux virtualization. Unlike raw disk formats that pre-allocate 100% of their designated size to physical storage, a .qcow2 file uses thin provisioning . QCOW2 Format - stereOS - Mintlify Staging the New QCOW2 Image Before booting the
Or use GUI:
What or management tool (Proxmox VE, libvirt/KVM CLI, oVirt) is hosting your environment?
This will create a 20GB QCOW2 file named my_new_vm_disk.qcow2 . Initially, the file will consume only kilobytes of space on your host.
