Package: virt-manager
Version: 0.9.1-1
Severity: important
Dear Maintainer,
I installed QEMU+KVM+libvirt-bin onto a server with Debian Wheezy.
I tried to access this server with virt-manager from my workstation
using key based SSH authentification without need to enter key
password due to running SSH agent.
When I try to connect to the server it shows that it connects but
then very quickly says it is not connected again.
virt-manager --debug shows:

Expected results:
virt-manager connects to the server or if it can't gives a meaningful
error message.
Regarding those netcat.openbsd bug reports that are probably related I
do have netcat.openbsd on my workstation and the server:

Opening an SSH connection to the server works without password due
to SSH agent:

libvirtd is running there:
root@frisbie:~# ps aux | grep libvirt | grep -v grep
root 1403 0.0 0.0 264532 6628 ? Sl 09:30 0:00
/usr/sbin/libvirtd -d
Aside the non-working functionality there seems to be a programming
error in "/usr/share/virt-manager/virtManager/manager.py" in function
connect_error, line 665 that might cause that I do not see an error
message. See the debug output above. Maybe thats the main bug here,
feel free to retitle as needed.
Ah, this seems to be in a check for some netcat arguments:
664 hints = []
665 if conn.is_remote() and re.search(r"nc: .* -- 'U'", details):
666 hints.append(
667 _("\n - The remote netcat understands the '-U'
option"))
So maybe this is actually a dupe of some of the netcat related bugs.
Feel free to merge if so.
Okay, when I fix this by moving some source lines around, I get the following
error message:
Unable to connect to libvirt:

- The 'libvirtd' daemon has been started
Unable to connect to libvirt:

On the console I have:

if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: Cannot recv data: Value too large for defined data type
So there seems to be another programming error.
So these are at least two bugs:
- local variable not defined on in
/usr/share/virt-manager/virtManager/manager.py on line 665
(I will attach a patch for this.)
- value too large bug in /usr/lib/python2.7/dist-packages/libvirt.py
Can you split my bug report into two as needed?
Thanks,
Martin
