Xen project Mailing List

Dear Guys,

please excuse me and take it as a new post

I was a little worked up so i decide i start right from scratch and since this are new Cisco Blade servers and not yet in procduction i had the liberty to play around

Now i do face a issue again which i feel is quite weird..

let me explain..

I did install centos 6.5 and xen as per the docs below and everything went smooth

-----------------

http://wiki.centos.org/HowTos/Xen/Xen4QuickStart

---------

now the server has 2 NIC and I can reach the server from out entire network..

xm info shows the below

to enable multiple guest network bridges to use multiple network cards i followed the link below

-------------------

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/chap-Virtualization-Pre_Red_Hat_Enterprise_Linux_5.4_Xen_networking.html

----

but when i run brctl show it only shows me

bridge name bridge id STP enabled interfaces
virbr0 8000.000000000000 yes

-----

where could I be going wrong .. is there any debugging i can do and which logs will help me

i tried looking at /var/log/xen/ directory but nothing much

Thanks and regards

simon

Have you tried to make your sysctl look like mine? I don't see any Xen
specific problem here so you should probably consult your local network
administrators / experts, as this problem might be related to your local
network setup.
