Hello I am trying to install xen. I am using this page as a guide: https://wiki.archlinux.org/index.php/Xen I have a problem where I can not get the commands for setting up the networking bridge to work. During the xen installation, I noted that it uses netctl instead of netcfg. I made those changes and if I boot my regular kernel it appears to work with a wifi connection. Here is the result of some command regarding networking with regular kernel. [root@t61p ~]# netctl list xenbridge-dhcp * wlan0-hs-dlink wlan0-hs-dlink.wifi-menu [root@t61p ~]# I believe this command shows that wlan0-hs-dlink is the active profile and is enabled at boot automatically. For instance: [root@t61p ~]# systemctl | grep hs-dlink netctl@wlan0\x2dhs\x2ddlink.service loaded active exited Networking for netctl profile wlan0-hs-dlink [root@t61p ~]# This is a result of systemd having netctl@wlan0\x2dhs\x2ddlink.service in the /etc/systemd/system/multi-user.target.wants directory. So it looks ok for having networking via wifi working in regular linux kernel. As far as xen and bridge goes, I created the following file /etc/netctl/xenbridge-dhcp with the following contents: Description="Xen Bridge connection" Interface=xenbr0 Connection=bridge BindsToInterfaces=(wlan0 wlan1 tap0) IP=dhcp Basically, I used the example given on the arch xen wiki page and changed eth0 to wlan0 and eth1 to wlan1. When I try to start the xenbr0 (bridge) I get an error about tap0 not found. This is the command I issue (bascially from the wiki) and the result from journalctl # netctl start xenbridge-dhcp -- Unit netctl@xenbridge\x2ddhcp.service has begun starting up.
