Hello. I want to use libvirt for toolstack of Xen (not XenServer) to set up Openstack system but, I'm new to libvirt so, I had some troubles on installing libvirt. I downloaded the source code, build and installed it, following here ( https://libvirt.org/compiling.html). However, when I type a command (# virsh 'xen:///system' list) to check if libvirt has been installed successfully, I can see an error message: error: failed to connect to the hypervisor
error: internal error: libxenlight state driver is not active
Of course, I confirmed that Xen was working well: root@node1:/home/nickeys# xl list
Name ID Mem VCPUs State Time(s) Domain-0 0 95656 32 r----- 5888.0
And I'm wondering why 'Using API' below is QEMU. How can I change that to Xen ? root@node1: /home/nickeys# virsh version
Compiled against library: libvirt 4.9.0 Using library: libvirt 4.9.0 Using API: QEMU 4.9.0 Running hypervisor: QEMU 2.11.1
I'm using libvirt 4.9, Xen 4.12 (the current latest) and Linux kernel 4.16.1. I want to know how to make the 'libxenlight state driver' active. Please let me know where I should check first to fix this wrong state, or any tip is also okay. Thanks.
