Hello everyone,
I'm trying to get eucalyptus v1.5.2 working on debian lenny 64bit, the
relevant info I can give you is as follows:

01:/etc/libvirt# cat libvirtd.conf|grep -v '#'
unix_sock_group = "libvirt"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"

There are two possible reasons for this error message
- The daemon closed the client connection because it mis-behaved
- The daemon crashed
Of these, the 2nd is the most likely. To check this, start the libvirtd
daemon manually, under GDB or valgrind, and then do whatever you do in
eucalyptus to make it break. Hopefully you'll then get a stack trace
from GDB, or a list of errors from valgrind. 0.4.6 is quite old now, so
you should report the bug to Debian's bug tracker with gdb/valgrind
info so they can evaluate whether its possible to fix/backport a patch
Alternatively you can upgrade to a newer version of libvirt, I'd recommend
0.6.4 which has proved quite stable, or even 0.7.0 though that's not has
as much exposure yet.
Regards,
Daniel
