I am totally lost in this UID/GID mapping. Maybe all this stuff is just beyond my competence. For now, I am writing a basic mydomain.xml file following these 3 wiki: LXC container from libvirt.org[1] Linux containers guide from Rad Hat 7[2] getting start with lxc from P.Berrange [3] This is the basic .xml file: <domain type='lxc'> <name>dahlia</name> <memory>409600</memory> <os> <type arch='x86_64'>exec</type> <init>/bin/init</init> * systemd is default and PID1 is init on my Arch box <vcpu>4</vcpu> </os> <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> * it is the path on Arch <console type='pty'/> </devices> </domain> Unfortunately : gabx@hortensia ➤➤ /drawer/vm # virsh define dahlia.xml error: Failed to define domain from dahlia.xml error: internal error: unexpected domain type lxc, expecting one of these: qemu, kqemu, kvm, xen What is wrong ?
