So hab jetzt xen von hand installiert, rennt wie schnittchen.

Als würde was am OvH Image nicht wollen. Gestern die Fehler und Versuche waren alle mit OVH Xen Image

[F4RR3LL]

baaaaaa noch nen weiteres Problem:

root@ns364736:~# xm create -c /etc/xen/gameserver.cfg
Using config file "/etc/xen/gameserver.cfg".
root@ns364736:~# Error: Device 769 (vbd) could not be connected. Failed to find an unused loop device

ab der 5ten DomU loop device steht in der lilo.conf per default 64 , damit dürften wohl ein paar mehr DomUs gehen als 4.
Dazu bräuchte ich auch eine Lösung, es sollen ja 9 DomUs werden.

Achja und nach einem reboot sind die networksettings der DomUs im eimer...

[F4RR3LL]

Hier mal eine Config, laufen tun alle DomUs nur ich komme halt sobald ssh abstürzt nicht mehr dran und das ist alles andere als sexy

/dev/xvc0 das Device existierte nicht, habe ich aber hinzugefügt. Hat nach einem Reboot aber auch nichts verändert.

Auch im Log konnte ich nix sinnvolles finden

Grün - die Farbe der Hoffnung! :-)

Poste doch mal die relevanten Auszüge der inittab auf der DomU, sowie von
/etc/xen/irc.cfg.
Dann überprüfe auch mal, ob im Dateiystem der DomU /dev/xvc0 existiert, wenn
nicht: mknod /dev/xvc0 c 204 187

Und letztenendes: steht im syslog der DomU nix aufschlussreiches drin?

[sledge0303]

Alternativ:

extra="console=xvc0 xencons=tty"

in der /etc/xen/irc.cfg einfügen.

[kro]

die DomU ist up, zeigt dir aber keinen Login an.

probier mal:
-> in deine config "extra='console=xvc0 xencons=xvc0'" hinzufügen
-> in der DomU: sed -i -e 's/tty1/xvc0' /etc/inittab
-> auch in der DomU: echo "xvc0" >> /etc/securetty

Servus,

ich habe nun auf meinem Server xen installiert und hab das eigentlich auch schon xfach gemacht.
Aber diesesmal hab ich ein Problem mit dem ich nicht klar komme.
Ich habe eine DomU erstellt mit xen-tools mich dann in diese local eingeloggt und sie configuriert. Alles ok. Routing am Server auch ok.

Dann kommt der Part an dem ich sie laufen lassen will.

Ich starte sie mit xm create -c /etc/xen/irc.cfg zB
Sie fährt dann teilweise hoch und bleibt an dem Punkt stehen und macht einfach gar nix mehr ..kein Fehler kein nix.
Habs jetzt xfach probiert.

Hier mal zum Nachlesen was sie macht wenn ich den Befehl eingebe. Evtl hat wer nen Tipp.
