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[1]. 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[2] 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. ----- [1] https://webmail.ami.org.pt/panic.jpg [2] 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. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
