I'm using the vif rate parameter to control outbound network bandwidth for Xen
guests. It works fine. However, when shutting down guests that have a rate
limit specified in the config file, then that creates zombie domains on the
machine. When shutting down domains that don't have a rate limit set, I don't
see any zombie domains at all, so I'm quite confident that the zombie domains
are resulting from the rate limiting.
Is this a known issue or is there something I can do in order to prevent the
appearance of zombie domains? I'm not seeing any error messages in the Xen or
system logs. Please find some more details on my configuration below. I'm using
Xen in bridged networking mode.
Thanks,
Anna
