Hi, I am having problems establishing an adsl connection in dom0 (but ONLY in dom0, without xen everything is ok). Following is my setup/situation: 1. Installed clean Fedora 7 (with virtualization option selected) 2. Booted with the non-xen kernel & setup adsl. Adsl connection works without any problems. 3. Rebooted with xen kernel into dom0. 4. adsl connection can no longer be activated These are literally ALL the steps I took with the system. Thus, it is as "out of the box" as it can get. When trying to activate the adsl-connection in the (fedora?) gnome network configuration utility with the "activate" button I get (after about 1-2 minutes): Cannot activate network device dslModem! and in the textbox in the error message window it says: /usr/sbin/adsl-start: line 215: 3470 Terminated $CONNECT "$@" > /dev/null 2>&1 In /var/messages it says: Jul 17 00:08:21 gaia pppd[3494]: pppd 2.4.4 started by root, uid 0 Jul 17 00:08:21 gaia pppd[3494]: Using interface ppp0 Jul 17 00:08:21 gaia pppd[3494]: Connect: ppp0 <--> /dev/pts/1 Jul 17 00:08:52 gaia pppd[3494]: LCP: timeout sending Config-Requests Jul 17 00:08:52 gaia pppd[3494]: Connection terminated.

Can anybody tell me why adsl does not work in the fedora 7 dom0? It used to work just fine with fedora 6. How do I get it to work? I have however remarked another detail that I believe might be linked to (or the cause of?) my problem. In dom0 when trying to bring up my adsl connection I get the following line before the first error occurs: Jul 17 00:08:21 gaia pppd[3494]: Connect: ppp0 <--> /dev/pts/1 This line puzzles me because in four years I have never seen "/dev/pts/1" used to connect to my adsl modem. It was ALWAYS "/dev/pts/0"! Of course this might a perfectly appropriate renaming of devices as happens a lot with xen but... Can anybody shed any light on this? Cheers, Arik

(assuming your network device is eth0 *and* up) there are some more options for pppoe (currently not installed on my box) to investigate more.> > > I have however remarked another detail that I believe might be linked to > (or the cause of?) my problem. > > In dom0 when trying to bring up my adsl connection I get the following > line before the first error occurs: > > Jul 17 00:08:21 gaia pppd[3494]: Connect: ppp0 <--> /dev/pts/1 > > This line puzzles me because in four years I have never seen > "/dev/pts/1" used to connect to my adsl modem.

(pppoe options) no ? AC not reachable => try with none xen kernel: no ? => try later. but you reported this part works with none xen kernel. 3. you can reach your AC (you see the AC mac address) and you need to debug it (see pppoe debug options) to see why => your adsl connection setting is faulty - i try to remember - => /etc/ppp/pppd.conf or something like that; look for debug, esp. timeout parameter settings, there are some !> > - Arik > > -- > Fedora-xen mailing list > Fedora-xen@redhat.com > https://www.redhat.com/mailman/listinfo/fedora-xen-- Ronald

Following is the exact result.

It''s very possible that this might be screwing with things for your pppoe software - maybe try using peth0 as the interface name on the pppoe command line? However, you''re going to run into problems with giving your Xen VM''s access to the DSL without some major changes to their init scripts so that your Xen DomU''s use a nat provided to them by Dom0.
