Hi Ian and Keir,
I'm sorry for delaying response.
Can you reproduce if you uninstall the RHEL5 xen/kernel and xen tools
and libs RPMs and then install binaries built from xen-unstable?
We will reproduce it with xen-unstable.hg.
We tested it with the same machine.
The environment is as follows.
Xen :
- xen-unstable.hg: cs15072
NICs :
- Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3)
- Intel Corporation 82545GM Gigabit Ethenet Controller (rev 04)
Guests :
- DomU
- DomVTi(RHEL5GA)
- DomVTi(RHEL5GA) + PV_ON_HVM(VNIF)
Others:
- SG and TSO flag: ENABLE
- Memory
・Domain0 : 1GByte
・Guest Domains : 2GByte
The test result was not reproduced as follows.
| Broadcom | Intel
----------------------------+---------------+---------------
DomU | Not broken | Not broken
DomVTi(RHEL5GA) | Not broken | Not broken
DomVTi(RHEL5GA)+VNIF | Not broken | Not broken
Next, the tg3 driver and the e1000 driver were replaced with RHEL5GA.
However, the result was not reproduced similarly.
Is there a correction related to this problem since xen3.0.3?
Best Regards,

Hi Ian,
Thank you for reply.
Is this is a 32b install of RHEL5 GA, or x86_64? I presume 32b.
As for this environment, 32bit version of RHEL5GA is installed.
Can you reproduce if you uninstall the RHEL5 xen/kernel and xen tools
and libs RPMs and then install binaries built from xen-unstable?
We will reproduce it with xen-unstable.hg.
Rather than disabling SG, what happens if you disable TSO?
When TSO is disabling, FTP data was broken. (enabling SG)
When SG is disabling, TSO automatically is disabling, too.
TSO SG Reproducibility
------------+-----------+----------------------
Enable Enable Broken
Enable Disable (Impossibility)
Disable Enable Broken
Disable Disable Not broken
What about checksum offload (TX and RX)?
TX and RX are enabling. When TX and RX are disabling, reproducibility didn't
change.
What happens with mem=4G?
We will reproduce it.
Best Regards,
