[Xen-users] Bridge Networking stops working at random times
Supermicro X7DWN+, XEON 5410, Centos 5.2, Xen 3.2.1 At what looks like random times network traffic over xen bridge stops working, the only way I found to fix it is a reboot. This sometimes takes 10 min, other times it may be up for 10 days. This happened with default xen that comes with RedHat EL 5.2 as well as a default install of Fedora 8. Any ideas?><>Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Bridge Networking stops working at random times
Hello, I am getting a similar problem that I''ve discussed in previous posts (with no solution that works so far). The only difference is that when my network stops working the VM tries to reboot and fails with some sort of error related to a duplicate machine ID. This seems to manifest itself when there is a high amount of simultaneous connections and/or high throughput. I am wondering if your problem may not be so random and might be occurring under the same conditions?

Re: [Xen-users] Bridge Networking stops working at random times
I am using broadcom PCI-e NICs for all my connections on VMs and the onboard nVidia for the XEN host console, so there is no e1000 driver built for my setup. I also have 2 bridges setup.
