[Xen-users] RE: network problem with 50 domUs

["Fischer, Anna" <anna.fischer@xxxxxx>]

It worked after you rebooted Dom0, or DomU? What Xen version is this, and what Dom0 kernel version? How do you know about the memory limit issue? What error messages do you get? Can you post that error log? How much RAM does the machine have, and I assume you are not using HVM guests? Are you attaching all guests to only a single bridge?

Subject: [Xen-users] network problem with 50 domUs

 

I have created 500 domUs in 10 physical servers. Each server contains 50 domUs.

After I have started 50 domUs using shell script which used for loop and xm create,

Every domU was successfully started and listed up with.

However, domU network did not work.

The interesting thing was that they became working after reboot manually. It seemed that Dom0

did not have enough memory to set virtual bridge properly.

I don’t really know why it happens.

Please explain more about it. Thank you in advance.
