[Xen-users] help with xen instalolation on debion ecth
Hello,
i''ve an HP proliant dl385g2 server with AMD64 Opteron processor.
i''ve rightly installed Debian Ecth and configured as Dom0.
I''ve installed the package via apt.
well i would install 7 virtual server... one as mail server, one as db
mysql server, 5 as web server.
i''m installed my first DomU.
i''ve created a LVM with my first DomU,
is a Debian Ecth too... i''ve followed this page instructions...
http://wiki.xensource.com/xenwiki/DebianDomU
the Dom0 network work right... but if i connetted with console to my
DomU the network don''t work... :(
i''ve connected with the command
#xm console myDomUname
after login if i try
# apt-get update
....
index files failed to download
....
if i try
# ifconfig
i''ve that output
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
i''ve no interface up... it''s right?
in xend-config.sxp i''ve
(network-script network-bridge)
(vif-script vif-bridge)
it''s right?
in myDomUname.conf i''ve setted
dhcp="dhcp"
after i try to assign a static ip
with
ip="192.168.1.211"
gateway ="192.168.1.1"
netmask="255.255.255.0"
but don''t work anyway ... :(
somebody can help me to set right configuration of network of my Server?
thanks
Michele

It''s really possible that the number is eth3 o eth14 and there is a reason for that: udev and no-mac associated to domU internal eth. I explain it: With udev and udev rules when a new dev (new MAC) is detected the system uses a NEW ethX because there is an association MAC-ethX in: /etc/udev/rules.d (see "25-iftab.rules" o "z25-net.rules"): ----------- # This file causes network devices to be assigned consistent names. # See udev(8) for syntax. SUBSYSTEM=="net", ACTION=="add", DRIVER=="?*", \ PROGRAM="iftab_helper %k", NAME="$result" ------------ So it''s possible that you have in that file more that one MAC detected so more than one eth created. In Debian Etch, when upgrading "udev" is installed so udev rules start working. To solve it the best option is to assign a MAC to your domU interface. So edit your /etc/xen/vm.cfg file: vif = [ ''ip=192.168.1.241, mac=00:16:3e:60:73:3d'' ] Note that there is a range of MAC that you can use for Xen virtual machines (I don''t knoiw it exactly).

Thank for your answer i''ve tried to set a static mac address for my DomU... but i have the same problem to use network into DomU. i put vif = [ ''ip=192.168.1.211, mac=00:16:00:00:00:01'' ] into my DomU config file i restarted my server... but... now when i enter in DomU console (xm console myDomUname) i''ve the follow message: netfront:device eth0 has flipping receive path if i do the following: # cat /proc/net/dev i see that i''ve lo and eth0 too but if i do # ifconfig i see only lo and no other interface what kind of error i do in configuration? :( _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
