Yes, but we should check if the error originates from virConnectOpenAuth
to make sure we're not even more confusing.
Could you add that too?
I'm not sure if I understood you. According to the code:
|def openAuth(uri, auth, flags):
|ret = libvirtmod.virConnectOpenAuth(uri, auth, flags)
|if ret is None:raise libvirtError('virConnectOpenAuth() failed')
|return virConnect(_obj=ret)
I would say that the error always originates from virConnectOpenAuth()
since this is the only place where an exception is thrown. The
virConnect() call looks like a constructor which can't fail / does not
throw anything.
I was thinking about parsing value which contains the error message.
However the message depends on the locale and shouldn't be used.
Furthermore I'm always getting connection reset by peer no matter if I
entered my password wrong or had a typo in the hostname.
openAuth() is called for all protocols so I modified my patch to give
this install ssh-askpass just if the protocol is ssh.

Bug#513599: Can't connect to remote host via ssh without ssh-askpass*
Package: virt-manager
Version: 0.6.0-6
Severity: wishlist
If someone is connecting to a remote host via ssh virt-manager fails to connect
if there is no auto-connect available (i.e. the remote key has a sshkey
with no passphrase).
The only solution is to install a tool which ask you for a password like
* ssh-askpass
* ssh-askpass-fullscreen
* ssh-askpass-gnome
Now, virt-manager will ask for the root password if neccessary and will
not bail out with this error message:
|Unable to open connection to hypervisor URI 'qemu+ssh://r...@box/system':
|class 'libvirt.libvirtError' Connection reset by peer
|Traceback (most recent call last):
| File /usr/share/virt-manager/virtManager/connection.py, line 486, in
_open_thread
|None], flags)
| File /usr/lib/python2.5/site-packages/libvirt.py, line 99, in openAuth
|if ret is None:raise libvirtError('virConnectOpenAuth() failed')
|libvirtError: Connection reset by peer
|
Please add depends/recommends on one of these tools. Maybe upstream
could add a hint or something.
