[Xen-devel] a domain VTx with the VNIF does hang.
Hi all, my name is Hirofumi Tsujimura.
We are porting and testing a PV-on-HVM in the IPF.
This is a first time to send mail.
I probably found the problem when I tested the VNIF.
My operation for the test is following.
1. create a domain VTx and attach the VNIF in it.
2. create a domain U.
3. send a packet to the domain VTx from the domain U with ping
command.
Then, the domain VTx does hang.
And, it outputs as follows.
The domain U and a domain 0 doesn''t do hang.

*** Please look at screenshots about the detail of the log. ***
The test environment is as follows.
- Architecture : x86
- Xen change set: 11683
- Domain 0 : kernel2.6.16.29-xen
- Domain U : kernel2.6.16.29-xen
- Domain VTx : kernel2.6.16
Probably, a domain VTx with the VNIF does Hang when it recieves a packet
from some domain U or from some domain VTx with the VNIF.
Additionally, I similarly tested the VNIF in the following environments
today(On October 3 2006).
- Architecture : x86
- Xen change set: 11686
- Domain 0 : kernel2.6.16.29-xen
- Domain U : kernel2.6.16.29-xen
- Domain VTx : kernel2.6.16
As a result, a kernel of domain VTx with the VNIF does panic when I use
"xm network-attach domainVTx eth1" in a domain 0.
Even if that command succeeds, it similarly does hang when it recieves a
packet.
What''s happend?
Thank you.

Re: [Xen-devel] a domain VTx with the VNIF does hang.
The patch which fix a inter-domain communication using rx-copy path was released in the changeset 11737. I confirmed that the problem was fixed in the changeset 11751. Thank you.
