What is a qcow2 file?

QCOW2 is a storage format for virtual disks. QCOW stands for QEMU copy-on-write. The QCOW2 format decouples the physical storage layer from the virtual layer by adding a mapping between logical and physical blocks.

Can QEMU work without KVM?

As previously mentioned, QEMU can run independently, but due to the emulation being performed entirely in software it is extremely slow. To overcome this, QEMU allows you to use KVM as an accelerator so that the physical CPU virtualization extensions can be used.

Is KVM faster than QEMU?

So for x86 to x86 virtualization, “raw” qemu is slow, but KVM (which uses qemu) is fast. Quite fast. So fast that it’s Red Hat’s recommended virtualization solution for RHEL.
