Select the downloaded .qcow2 file as the existing disk image.

Always check the checksum to ensure you have the legitimate "new" version, not a corrupted download. pavmkvm801qcow2 new

I can provide more specialized configurations if you tell me your setup details. Are you looking to build a active-passive cluster, or do you need a specific Ansible playbook script to automate this KVM deployment? Share public link

While raw disks are often considered the performance king, you can tune QCOW2 to handle heavy I/O loads like databases or high-traffic firewalls. New overlay file: pavmkvm801

While dynamic expansion saves physical space initially, it features the largest performance overhead compared to raw disk alternatives when a system must allocate new clusters dynamically. For instance, operating system installations or database initializations trigger constant write calls. To bypass this latency penality, use the preallocation=metadata or preallocation=falloc modifier during creation to map out block layouts without filling them with empty zeroes. Discard and TRIM Support

Log out and back in.

Using virt-manager or virsh (QEMU/KVM), create a new virtual machine.

To reclaim this space and shrink the physical file back down, you can use the qemu-img utility on the KVM host. This process is called "discarding" or "hole punching." Are you looking to build a active-passive cluster,

System templates can serve as read-only base images. New instances only write delta changes to distinct pavmkvm801qcow2 target files, saving up to 80% of initial disk array capacity. Step-by-Step Deployment Guide
