vxctl vm console test-ubuntu --follow 1. Live Snapshots with Minimal Downtime Traditional snapshots freeze I/O for several seconds. VX Manager 1.6.4 implements copy-on-write (CoW) with dirty page tracking:
vxctl snapshot create test-ubuntu --name "pre-upgrade" --live The entire operation completes in under 500ms for VMs with less than 10GB of active memory. Create a golden image from an existing VM: vx manager 1.6.4
[api] workers = 16 queue_size = 2048 Then restart: sudo systemctl restart vxmanager We ran a series of tests on identical hardware (AMD EPYC 7402, 128GB RAM, NVMe RAID10) with 20 concurrent Ubuntu VMs. vxctl vm console test-ubuntu --follow 1
vxctl network create --name "dmz" --subnet 10.10.10.0/24 --vlan 101 vxctl vm attach-network web-server-01 --net dmz --ip 10.10.10.50 One of the most celebrated features in VX Manager 1.6.4 is the revised VXScript engine. Below is an example that automatically scales resources based on CPU load: Create a golden image from an existing VM:
| Component | Minimum | Recommended | |-----------|---------|--------------| | | Windows 10 / Ubuntu 20.04 / macOS 11 | Windows Server 2022 / Rocky Linux 9 | | CPU | 2 cores @ 2.0 GHz | 8 cores @ 3.0 GHz+ | | RAM | 4 GB (host) | 16 GB+ (host) | | Storage | 2 GB for binaries | 10 GB for logs & cache | | Hypervisor | One of: VirtualBox 6.1, KVM, ESXi 7.0 | KVM + QEMU 7.2 |
VX Manager 1.6.4 drops official support for VMware Workstation 14 and older. ESXi 6.7 remains partially supported but without live migration. Step-by-Step Installation Guide Installing VX Manager 1.6.4 is straightforward. Below is the process for a Linux-based host (Ubuntu 22.04 LTS), which is the most common deployment scenario. Step 1: Download the Binary Avoid third-party mirrors. Obtain the official checksum-signed release from the repository:
// auto_scale.vxs register_event("vm_cpu_threshold", vm: "web-server-01", threshold: 85, // percent duration: 120, // seconds action: function(event) let current_vcpus = get_vm_cpus(event.vm_id); let new_vcpus = current_vcpus + 2; set_vm_cpus(event.vm_id, new_vcpus); log("Scaled " + event.vm_id + " from " + current_vcpus + " to " + new_vcpus); ); Run the script with:
