Patch src/virtManager/console.py to use nc or netcat from /usr/bin

That code is typically run on a remote system, so doing a local bin check is not valid. What exactly are you trying to accomplish, use netcat if nc doesn't exist? Is suse's nc named netcat? What's the output of netcat -h

I tried to adopt the patch suggested by Andreas in 2009.

See http://www.redhat.com/archives/et-mgmt-tools/2009-January/msg00072.html

You're right.  The goal is to use netcat if nc doesn't exist.

The patch in its unconditional version is part of the Virtualization:virt-manager project of the openSUSE Build Service.  See http://download.opensuse.org/repositories/Virtualization/

Can you provide the output of netcat -h on your machine? Does libvirt carry a similar patch to s/nc/netcat/g or something?

output of netcat -h

libvirt includes a patch to use netcat (if available) or socat.

Looks like I've to find a way to check if we have the binary on the other side of the connection.

/usr/bin/nc is available from the netcat-openbsd package.  Sorry for all the stupid noise.

The SUSE virt-manager package should use this binary and no more patch is required.

Probably a good idea to have your libvirt add a dep on that package.

Yes.  I filed https://bugzilla.novell.com/show_bug.cgi?id=611023 to track this on the SUSE side.
