xen-3.0 no network in dom0

xen-3.0 no network in dom0

[Heiko Lehmann]

Hello.

I have installed xen-3.0-testing.
Now the networkadapter does not working yet.



-------------------------------------------------------
Problem:
- no network in dom0 with xen-3.0


Diag:
- lt.
http://lists.xensource.com/archives/html/xen-users/2005-10/msg00369.html
   the cause of the problem is the locale variable
  - s. conf_locale
  -> In this case it is not the cause
- i have acpi disabled, but the problem exists still
- it seems to be a hardware problem
  - s. line NETDEV in dmesg_out
  - s. proc_interrupts
    -> IRQ-Count=0
    - after the load modules the counter should be not equal Null

- the problem exists with the following modules:
    e100, eepro100
- with xen-2.0.7 there is not the problem


  - Whats going wrong?


- the complete documentation is avaible at

No.
(links to ../init.d/xend do not exist yet)

/etc/init.d/xend start
 ## -> no network

/etc/xen/scripts/network-bridge start
 ## -> no network

Link veth0 is missing.
This may be because you have reached the limit of the number of interfaces
that the loopback driver supports.  If the loopback driver is a module,
you
may raise this limit by passing it as a parameter (nloopbacks=<N>); if the
driver is compiled statically into the kernel, then you may set the
parameter
using loopback.nloopbacks=<N> on the domain 0 kernel command line.

aladin:/etc/xen/scripts# ifconfig -a | grep veth0
veth0     Link encap:Ethernet  HWaddr 00:00:00:00:00:00

Does it work before you start xend? (i.e. "chkconfig --del xend")

If so, run "sh -x /etc/xen/scripts/network-bridge start"
