FreeBSD iscsi 10.0-ALPHA5 FreeBSD 10.0-ALPHA5 #0 r256092: Sun Oct 6 22:30:23 UTC 2013 root at snap.freebsd.org:/usr/obj/usr/src/sys/sys/GENERIC amd64
[duplicate of misc/182884, which was filed under the wrong category]
Under a NetBSD 6.1.2/amd64 and Xen 4.2.3, FreeBSD 10.0-ALPHA5 network is unstable/unusable.
Trying to ssh in to the virtual machine does not work.
On the first attempt, ssh from the client hung in connect() and at the FreeBSD domU console there was a panic.
On the dom0 console, the following was shown:
xvif3i0: packet size 1610 too big
xvif3i0: packet size 0 too big
xvif3i0: packet size 1544 too big
Disabling txcsum and rxcsum makes the client hang in select() instead, but on the FreeBSD we still see "xn_txeof: WARNING: response is -1!", while simultaneously on the dom0 the following is printed to the system console: "xvif5i0: packet cross page boundary". The SSH connection is of course never established.
 http://lists.freebsd.org/pipermail/freebsd-xen/2011-May/000940.html -- I saw & reported this same error on 9.x two years ago. It was fixed. Also, I run a 10-CURRENT snapshot from maybe half a year ago and everything works as expected there as well.
