Hello All, I really need some help here. I posted a previous message, but never got a reply. I''m trying to get Dom0 connectivity. Currently it doesn''t work. Centos 5.5 kernel-xen.x86_64 2.6.18-194.11.1.el5 installed xen.x86_64 3.0.3-105.el5_5.5 installed xen-libs.x86_64 3.0.3-105.el5_5.5 installed When it''s booted networking breaks. The o/s can''t even get updates. The only fix for Dom0 is to run /etc/xen/scripts/network-bridge stop What do I need to fix this? Currently the box has only one network card. Do I need another? Guest OS''s work fine either using fixed or dhcp natd The guest OS''s are even reachable when their up from the network. Please help. It seems like a bridge configuration issue. Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Define bridge via OS tools on clean CentOS 5.5 instance like in :-
http://wiki.libvirt.org/page/Networking
Setup Xen 3.1&(3.0.3 kernel&tools) via the Net. I believe the issue now
is here,
regardless you installed via DVD ( or no ?).
Anyway you can setup Xen via DVD first and then :-
1. If using Xen it is recommended to disable its network munging by
editing /etc/xen/xend-config.sxp and changing the line
(network-script network-bridge)
To be
(network-script /bin/true)
2. Define DHCP bridge per http://wiki.libvirt.org/page/Networking
See what happens ?
Boris.

Hello All,
I really need some help here. I posted a previous message, but never
got a reply.
I''m trying to get Dom0 connectivity. Currently it doesn''t
work.
Centos 5.5
kernel-xen.x86_64 2.6.18-194.11.1.el5 installed
xen.x86_64 3.0.3-105.el5_5.5 installed
xen-libs.x86_64 3.0.3-105.el5_5.5 installed
When it''s booted networking breaks. The o/s can''t even get
updates.
The only fix for Dom0 is to run
/etc/xen/scripts/network-bridge stop
What do I need to fix this?
Currently the box has only one network card. Do I need another?
Guest OS''s work fine either using fixed or dhcp natd
The guest OS''s are even reachable when their up from the network.
Please help. It seems like a bridge configuration issue.
Thanks

While I think the concept of libvirtd is good, I still think it needs alot of work. For example, I found that it was very buggy with Xen 4.0 and even broke across different versions of Xen 3. My advice is to just learn xm and do everything manually. Then you get a good understanding of how Xen works Just my 2 pence _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
It''s funny, guys. RH invested so much in Libvirt ( 0.8.2 current)
,virtinst, python-virtinst ,
virt-install, virt-manager. It works for Linux guests just fine either via
"br0" or "virbr0"
under Xen Hypervisor ( up to 4.0.1-rc6) on top of F12,F13.
Sure , you can get rid from virt-manager ( virt-install) by not installing
libvirt at all ;)

Don''t do that.
Just ignore if you want to.
Touching "virbr0" will affect
daemon "libvirtd", e.g. all related Libvirt''s stuff.
