Virtualization, written down.
Practical posts on KVM, KubeVirt, moving off VMware and operating a virtual estate. Most are vendor-neutral; posts about Victor say which revision they were checked against.

A realistic VMware exit starts with the inventory
A practical runbook for leaving vSphere: export the estate, assess it offline, size the target, map networks and storage in a reviewable plan, pilot, then migrate cold.
READ THE POST VICTOR / 12 MINChoose an install path before you choose a machine
Victor Host ISO, the appliance, Helm, the air-gapped bundle or the evaluation installer: what each path installs, what it needs, how to verify it, and what to do on day one.
READ THE POST VICTOR / 9 MINCommunity is the foundation, not a trial
Where the line between Victor Community and Enterprise sits, why each Enterprise feature exists, how the offline license behaves, and how to decide which edition an estate needs.
READ THE POST VMWARE EXIT / 9 MINConverting VMware guests to KVM: virt-v2v, qemu-img and what breaks
How VMDK formats map to raw and qcow2, why a converted disk is not a converted guest, what virt-v2v changes inside Linux and Windows, and the checks to run before you start.
READ THE POST KVM / 9 MINCPU models and live migration
Host-passthrough, host-model and named CPU models in QEMU and libvirt, what x86-64-v2/v3/v4 mean, and how to pick a CPU baseline that lets VMs live-migrate across mixed hardware.
READ THE POST OPERATIONS / 11 MINGive the assessor evidence, not screenshots
What assessors ask for under NIST SP 800-53, why screenshots fail them, and how Victor's signed evidence package, audit chain and posture checks give them something they can verify offline.
READ THE POST OPERATIONS / 12 MINHA is only as good as its fence
Restarting a VM elsewhere is easy. Making sure the old copy can't keep writing is the hard part. How fencing works, what each method guarantees, and how Victor fences KVM hosts before restarting VMs.
READ THE POST VMWARE EXIT / 9 MINKeeping a VM's identity through a migration
Which identifiers a VM carries (SMBIOS UUID, instance UUID, MACs, VM Generation ID, NIC names), what depends on them, and how to keep them when moving from VMware to KVM.
READ THE POST KUBEVIRT / 7 MINKubeVirt from the ground up
How KubeVirt turns a VirtualMachine object into a QEMU process inside a pod: the components, the CRDs, run strategies, scheduling, virtctl, live migration and when it fits better than a classic KVM cluster.
READ THE POST KVM / 8 MINKVM, QEMU and libvirt: who does what
"KVM" usually means a stack: a kernel module, a userspace emulator and a management daemon. What each layer does, how to inspect it, and where Incus, Proxmox VE, OpenStack and KubeVirt sit on top.
READ THE POST KVM / 8 MINLive migration under the hood
How QEMU/KVM moves a running VM: dirty-page tracking, pre-copy convergence and downtime limits, auto-converge, post-copy and multifd, storage, CPU models, and the libvirt knobs that control them.
READ THE POST VICTOR / 12 MINOne control plane. Two VM engines.
Why run KVM and KubeVirt virtual machines side by side, what Victor unifies across them, where the engines still differ, and how to choose an engine per workload.
READ THE POST KUBEVIRT / 8 MINStorage for KubeVirt: CDI, DataVolumes and golden images
How KubeVirt VMs get their disks: container disks, PVCs and DataVolumes, CDI import and clone sources, golden images with DataSources, storage profiles, RWX for live migration, snapshots and backends.
READ THE POST VMWARE EXIT / 8 MINWhat changed in VMware licensing, and what it means for your renewal
A dated, sourced summary of VMware licensing changes since Broadcom's acquisition, and the inventory and planning work to finish before your next renewal.

Prefer the operating detail?#
The product documentation covers installation, edition boundaries, migration commands and known issues. Release notes tell you which revision an artifact actually contains.
