I'm having an issue with Xen guests on a Dell 2950 that is using the
Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet
# ethtool -i peth0
firmware-version: 6.2.14 bc 5.0.4 UMP 1.1.9
Running the 2.6.18-274.3.1.el5xen kernel
In the DomU guests trying to copy files larger than about 1-2 Mb causes
the network interface to freeze up, resulting in connection timeouts or
stalled rsync/scp transfers.
A few mailing list postings suggest that this is a bug in the IPMI
management portion of the firmware and that there is a firmware
workaround that you can try using a dos cd and utility:
Is there a linux utility that will do this, or another work around?
