Seeing the same thing trying to connect to my CentOS 5.2 Xen server:

Unable to open connection to hypervisor URI 'xen+ssh://root@hammer/':
<class 'libvirt.libvirtError'> cannot recv data: Connection reset by peer
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 483, in _open_thread
    None], flags)
  File "/usr/lib/python2.5/site-packages/libvirt.py", line 98, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: cannot recv data: Connection reset by peer

libvirt-0.6.0-1.fc10.i386

Problem seems to be related to asking for the root ssh-key pashprase and or root's password on remote, which I'm never prompted for.  strace seems to show a Gtk error for ssh-askpass:

20646 write(2, "\n(ssh-askpass:20646): Gtk-WARNING **: cannot open display: :0.0\n"..., 64) = 64


If I start virt-manager as root rather than as myself and enter root's password, I can connect fine.
