Virtualization Management (KVM & OpenVZ)
Production infrastructure operations & expert administration
Expert hypervisor management for KVM and OpenVZ compute nodes. Bridged networking, LVM/ZFS storage pools, resource tuning, and live VM troubleshooting.
Engineering Scope & Deliverables
Concrete administration, tuning, and incident resolution capabilities for this environment.
KVM Hypervisor Host Administration
Linux KVM / QEMU virtualization management, hardware virtualization (VT-x/AMD-V) pass-through, bridged network adapters, and virsh CLI management.
OpenVZ / Virtuozzo Container Nodes
OpenVZ 7 container node operations, kernel memory allocation, vzctl / prlctl command administration, and container density optimization.
Bridged & Routed Virtual Networking
Configuring Linux bridges (br0), Open vSwitch (OVS), IPv4/IPv6 subnet routing, MAC address IP binding, and ARP table troubleshooting.
Storage Pools & LVM Volume Management
LVM thin pools, ZFS zpools, Ceph block storage integration, RAW/QCOW2 disk image allocation, and live guest volume expansions.
Hypervisor Node Crash Recovery
Diagnosing compute node kernel crashes, unblocking stuck VM disk I/O threads, repairing damaged QCOW2 images, and live host migrations.
Resource Overselling & Fair Allocation
Tuning CPU pinning, memory ballooning (virtio-balloon), KSM (Kernel Samepage Merging), and disk I/O rate limits to prevent 'noisy neighbors'.

Frequently Asked Questions: Virtualization Management (KVM & OpenVZ)
Common questions about scopes, access models, SLAs, and onboarding.
Something else? Ask an engineer.
What is the key architectural difference between KVM and OpenVZ?
KVM provides true hardware-assisted virtualization with independent kernels for each virtual machine (supporting custom kernels, Docker inside VM, and Windows). OpenVZ uses OS-level containerization where all containers share the host's Linux kernel.
Can you manage bare-metal hypervisor nodes running Proxmox or raw CentOS/AlmaLinux KVM?
Yes. We configure and manage standalone Linux KVM nodes, Proxmox VE clusters, and OpenVZ 7 hosts via CLI and control panels.
