XO Lite is a built-in, free local web interface available directly on your host IP for basic VM management. Xen Orchestra (from sources) is a fully-featured, free version you compile yourself, perfect for homelabs and testing. XOA (Xen Orchestra Appliance) is the paid, enterprise-ready turnkey virtual machine provided by Vates, offering 24/7 commercial support and SLA guarantees.
Unlike some legacy hypervisors, XCP-ng utilizes the XAPI Database to maintain the state of all operations. This database performs continuous, heavy write cycles. Installing XCP-ng on standard USBs or SD cards will rapidly deplete their lifespan and crash your host. ServerMO enforces SRE best practices by installing your hypervisor strictly on durable Datacenter SSDs.
This is a common issue when XCP-ng Guest Tools (`xe-guest-utilities`) are not installed in the guest OS. Guest Tools are absolutely mandatory. Without them, the hypervisor cannot detect the VM's IP address, manage dynamic memory, or perform safe "soft shutdowns."
XCP-ng requires a dedicated Storage Repository (SR) for ISO files. You must connect to your host via SSH and create a local ISO SR directory (e.g., `xe sr-create name-label=LocalISO type=iso...`). Once created, you can securely copy (`scp` or `wget`) your ISOs into that directory to make them available for VM creation.
Yes. XCP-ng (8.1+) combined with Xen Orchestra features a Native ESXi Import Wizard. You can connect directly to your vCenter or ESXi API and live-import virtual machines without the hassle of manual OVA/OVF exports. ServerMO provides the unmetered 10Gbps backend networks needed to execute this migration seamlessly.
If you plan to use modern software-defined storage (like ZFS or Ceph/XOSTOR), Hardware RAID is strongly discouraged as it blinds the filesystem’s self-healing checksum mechanisms. ServerMO provisions Direct PCIe NVMe lanes or HBAs in IT-Mode to give the hypervisor complete block-level control. For standard EXT/LVM deployments, hardware RAID can be used to offload I/O, but IT-Mode is preferred for enterprise storage flexibility.
