![]() ![]() If VT-x is disabled, you should find the following lines in the resulting output: (XEN) CPU0: VMX disabled by BIOS. Luckily, the VT-x status of your Xen system may be confirmed by running the “xl dmesg” command in Dom0. Libxl: error: libxl_create.c:928:initiate_domain_create: cannot make domain: -3 Libxl: error: libxl_create.c:564:libxl_domain_make: domain creation fail: Invalid argument Parsing config from /etc/xen/hostname.cfg ![]() ![]() For example, with VT-x disabled, the xl create error message may resemble this output: # xl create /etc/xen/hostname.cfg This is complicated by the fact that error messages encountered when running an “xl create” command on a VT-x disabled machine are not necessarily explicit. TXT needs to be disabled Ī common source of frustration for first-time HVM users is that VT-x is disabled by default in most BIOS.BIOS settings required to run a HVM DomU include the following enabled and disabled options: HVM BIOS Configuration RequirementsĪs HVM instances require hardware emulation at the hardware level, your system’s BIOS settings must be properly configured. That’s where HVM comes in handy: if there’s no PV version available, the user still has the option of installing the operating system using a HVM DomU.Īs with previous tutorials, this guide uses Xen Project Hypervisor version 4.8 as included in the old stable release of Debian 9 (Stretch), the operating system installed on Dom0. In other words, OS providers don’t always supply Xen-aware, PV versions of their releases. The simplest answer to this question is that PV operating systems (“OS”) aren’t always available. In this guide, we install the latest version of FreePBX Distro, an open source communications server, on a HVM DomU.įirst things first. Now that we’ve covered creating and deleting paravirtualized (“ PV“) virtual machines in Xen Project, it’s time to learn how to create a hardware virtual machine (“HVM”). Step 5 – Modify DomU Configuration File.Step 4 – Install HVM DomU Operating System.Step 3 – Create HVM DomU Configuration File.Step 2 – Create HVM DomU Logical Volume. ![]()
