Dear Guys, As
you all aware of the issue i had been having for the last month or so
regarding xen DOMU unable to communicate outside DOM0 and really
grateful to all the wise responses I have got and moreover your precious time As I said before we got new cisco blade servers and a Nexus switch. now today I did the following I had downloaded before CentOS 5.5 x86 64 Hypervisor Edition (Minimal) and i did use it to format and install on one blade. i
used the same ip settings as my other centos 6.5 Xen server and created
a new VM in bridge mode and voila everything worked in the first go
with no issues from the new DOMU i can reach the internet and my whole network below the setting of the 2 machines ------------------------- On Centos 6.5 x64 running dmesg shows Booting paravirtualized kernel on Xen Xen version: 4.2.3-28.el6 (preserve-AD) Xen: using vcpuop timer interface brctl show displays bridge name bridge id STP enabled

So its clear that there is no hardware or network issue. the only 2 things are the centos OS and xen for sure I dont thing is the OS I there anything I am missing in xen or is there any way I could debug the xen installation appreciate your thoughts and wise ideas. if any more info is required pls do let me know I can start centos 5x and xen 3 in production but want to get centos 6.5 and xen 4 deployed regards simon On Wednesday, February 26, 2014 1:05 AM, sbdcunha <guy20034u@xxxxxxxxx> wrote: Dear Adam an Guys, As per your post I did try as you said Alan ..
