Thanks, I missed that. Now I get this: $ virsh --connect qemu:///system error: failed to connect to the hypervisor error: internal error: unexpected QEMU URI path '/system', try qemu:///session But now I see virsh opening the socket, writing, etc. The server log shows this: 2019-04-29 15:32:07.306+0000: 20863: info : libvirt version: 5.2.0 2019-04-29 15:32:07.306+0000: 20863: info : hostname: koji 2019-04-29 15:32:07.306+0000: 20863: error : virDBusGetSessionBus:169 : internal error: Unable to get DBus session bus connection: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 2019-04-29 15:32:24.534+0000: 20852: error : qemuConnectOpen:1127 : internal error: unexpected QEMU URI path '/system', try qemu:///session 2019-04-29 15:32:24.534+0000: 20851: error : virNetSocketReadWire:1803 : End of file while reading data: Input/output error I also wonder if dbus is important, and if so, how to fix it. > Anyway, you'll need to run libvirtd privileged, otherwise it'll get > EPERM when trying to do almost anything. I'm aware of that, I want to try and see the limitations, and maybe get around them by using capabilities? _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
