I'm copying the installer from my dom0 to my domU (48M file) the file transfer stalls out and on the domU I get this kernel message: i.e. dom0: # scp xen-3.0-x86_32-rhel4.1.bin.tar domU:/mnt/sources root@domU's password: xen-3.0-x86_32-rhel4.1.bin.tar 0% 196KB 0.0KB/s - stalled -K domU: dmesg | tail -n 1 Received packet needs 8 bytes more headroom. tail /var/log/message: Dec 5 16:28:06 domU kernel: Received packet needs 8 bytes more headroom. Dec 5 16:28:59 domU last message repeated 10 times To the best of my knowledge this only happens on network traffic between the dom0 and the domU. It appears to be similar to this message: http://lists.xensource.com/archives/html/xen-devel/2004-09/msg00354.html I built and installed my own kernel from the xen-unstable-src.tar.gz previously and ran without problems on this same hardware. -Mike
