Re: [Xen-users] Packets stuck in the ethernet tx queue

[George Shuklin <george.shuklin@xxxxxxxxx>]

First time I hear something like that.

May be issue can be related to 'grace ARP' (which VM must send after migration, but some of kernels doesn't)?

In any way, hypervisor is not processing network traffic in any way. This is task for netback/front driver and bridge/swich software in dom0.

Hi,

 ÂWe have noticed that sometimes the packets are getting stuck in the TXQ of the

ethernet driver in the guest VM running on top of XEN hypervsior which is part of xencenter 6.0

(xen hypervisor version 4.1.0).

 ÂSometimes it appears as if the packets are draining but not making it out of the hypervisor

as we don't see them at the destination VM.

 ÂCan you pls give any helpful pointers ?

 ÂThanks,
