On windows virt-viewer take these from certificates for
"Z:\usr\i686-pc-mingw32\sys-root\mingw\etc\pki" which i guess is hardcoded
in the code...(dont know y)
i tried "./configure --sysconfdir=C:\pki\"
but this didnot work...

the certificates that i user here have to be correct because.. these
certificates are the same when i connect from a different linux machine
there i dont get the ERROR message. but still nothing happens.

These are the results when i tried running virt-viewer using the following
URI:


1.
LIBVIRT_DEBUG=1 virt-viewer -c qemu://FC11-KVM/session 2

 result:
here i dont think there is an issue with the certificates:
what happens here is a small window pops up with the message "Conneting to
vnc server" thats it and then the message goes.

When i tried these same commands on the same machine where the libvirtd is
running:

it works fine. with
qemu+tcp:///session 2

qemu:///session 2

i also tried to debug the virt-viewer-0.2.0 code.

the only thing that i could find out was that in src/main.c in function int
main(.....)

line 97 : gtk_main();

after reaching this line

1. On the same machine the code hangs and the vnc display is shown and i can
view my guest machine.

2. On the remote machine it doesnot stops here and comes out with the
message on the popup saying connecting to vnc server.


------------------------

On windows im still facing the problem with certificates because the same
certificates works on remote linux machine.

but using "qemu+tcp://FC11-KVM/session 2"... atlease a new window pops up
which does not respond...

Do we have to do any configuration on libvirtd to make virt-viewer to work
over tcp and tls because it works fine from a remote linux machine over ssh.

------------------------

has any1 have got any success running virt-viewer on windows...??
