Comment 3 Jiri Denemark 2011-12-06 03:47:41 EST

This is already fixed upstream by v0.9.8-rc2-4-g8fcee13:

commit 8fcee135e816a59bea96768feb15e6f32db328ef
Author: Guido Günther <agx@sigxcpu.org>
Date:   Sun Dec 4 15:26:23 2011 +0100

    remote_driver: don't fail if keepalive check fails
    
    Otherwise connections to older libvirt abort with:
    
    $ virsh -c qemu+ssh://host.example.com/system list
    error: invalid connection pointer in virDrvSupportsFeature
    error: failed to connect to the hypervisor
    
    Tested against 0.8.3 and 0.9.8-rc2.

Comment 4 Daniel Veillard 2011-12-06 03:49:18 EST

Confirmed, that commit fixes it for me too !

I tested with libvirt-0.9.8-1.el6.x86_64 and passed.

Comment 7 Huang Wenlong 2012-01-09 21:37:08 EST

Verify this bug with 
libvirt-0.9.9-1.el6.x86_64

Host: libvirt-0.9.4-23.el6_2.4.x86_64

Client :

## virsh -c qemu+ssh://10.66.85.216/system list
