Description of problem: unable to open connection to libvirt management daemon. Unable to connect to Fedora 10 install from Fedora 9 machine. Unable to connect to Fedora 9 machine from Fedora 10. No connection problem between Fedora 9 machine and CentOS 5.2 Version-Release number of selected component (if applicable): virtual machine manager 0.6.0 libvirt-0.5.0-1.fc10.i386 How reproducible: always Steps to Reproduce: 1. start virtual machine manager 2. add connection 3. Qemu, remote connection over ssh, IP address Actual results: when connecting from F9 to F10 error box with following message: Unable to open connection to hypervisor URI 'qemu+ssh://root@10.100.100.89/system': <class 'libvirt.libvirtError'> Connection reset by peer Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 439, 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 when connecting from F10 to F9 error: Unable to open connection to hypervisor URI 'xen+ssh://root@10.100.100.83/': <class 'libvirt.libvirtError'> Connection reset by peer Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 483, 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 Expected results: completed connection Additional info:
Seeing the same thing trying to connect to my CentOS 5.2 Xen server: Unable to open connection to hypervisor URI 'xen+ssh://root@hammer/': <class 'libvirt.libvirtError'> cannot recv data: Connection reset by peer Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 483, in _open_thread None], flags) File "/usr/lib/python2.5/site-packages/libvirt.py", line 98, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: cannot recv data: Connection reset by peer libvirt-0.6.0-1.fc10.i386 Problem seems to be related to asking for the root ssh-key pashprase and or root's password on remote, which I'm never prompted for. strace seems to show a Gtk error for ssh-askpass: 20646 write(2, "\n(ssh-askpass:20646): Gtk-WARNING **: cannot open display: :0.0\n"..., 64) = 64 If I start virt-manager as root rather than as myself and enter root's password, I can connect fine.
