Off-hand, that looks right; I just double-checked
http://libvirt.org/migration.html to make sure that it looks like a
valid native migration usage. But do be aware that --copy-storage-all
is poorly tested, and also that it currently requires you to pre-create
a destination file by the same name (there has been talk about patching
libvirt to auto-create the files, but that patch is still in the work,
and for back-compat reasons, it would require you to pass another option).
error: Unable to read from monitor: Connection reset by peer
This most likely means that qemu on the receiving end died quite early;
perhaps looking at /var/log/libvirt/qemu/node1.www.log will give you
more clues why.
