 |
|
Hi dear all,
I have a xen domU I can ssh connect to as root as well as user  .
This domU can be stopped via virt-manager. i.e. libvirt is at least partially working.
But I have a failure when I try as follows: | Code: | 1) as root:
virsh -c xen+ssh://root@xendomu0
root@xendomu0's password:
erreur :server closed connection: nc: using stream socket
erreur :impossible de se connecter à l'hyperviseur
2) as user:
virsh -c xen+ssh://user@192.168.0.30
Enter passphrase for key '/home/luc/.ssh/id_dsa':
erreur :server closed connection: nc: using stream socket
erreur :impossible de se connecter à l'hyperviseur |
Plz note that netcat6 must be installed on the domU because of a call to /usr/bin/nc wjthin the connect process.
Nevertheless, this was not enough to reach success 
Also did allow AllowTcpForwarding and PermitTunnel for the domU sshd, but no improvement.
libvirt USE flags as follows:
| Code: | - - avahi : Add avahi/Zeroconf support
- - caps : Use Linux capabilities library to control privilege
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml
- - iscsi : Allow using an iSCSI remote storage server as pool for disk image storage
- + json : Support QEmu 0.13 JSON-based interface, using dev-libs/yajl.
- + libvirtd : Builds the libvirtd daemon as well as the client utilities instead of just the client utilities
- - lvm : Allow using the Logical Volume Manager (sys-apps/lvm2) as pool for disk image storage
- + lxc : Support management of Linux Containers virtualisation (app-emulation/lxc)
- - macvtap : Support for MAC-based TAP (macvlan/macvtap). For networking instead of the normal TUN/TAP. It has its advantages and disadvantages. macvtap support requires very new kernels and is currently evolving. Support for this is experimental at best
- + network : Enable networking support for guests
- - nfs : Allow using Network File System mounts as pool for disk image storage
+ + nls : Adds Native Language Support (using gettext - GNU locale utilities)
- - numa : Use NUMA for memory segmenting via sys-process/numactl
- - openvz : Support management of OpenVZ virtualisation (see sys-kernel/openvz-sources)
- - parted : Allow using real disk partitions as pool for disk image storage, using sys-block/parted to create, resize and delete them.
- - pcap : Support auto learning IP addreses for routing
- - phyp : Support management of virtualisation through the PHYP hypervisor protocol.
- - policykit : Enable PolicyKit authentication support
+ + python : Adds support/bindings for the Python language
- - qemu : Support management of QEmu virtualisation (one of app-emulation/qemu, app-emulation/qemu-kvm or app-emulation/qemu-spice)
+ + sasl : Adds support for the Simple Authentication and Security Layer
- - selinux : !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
- - udev : Enable sys-fs/udev integration (device discovery, power and storage device support, etc)
- - uml : Support management of User Mode Linux virtualisation
- - virtualbox : Support management of VirtualBox virtualisation (one of app-emulation/virtualbox or app-emulation/virtualbox-ose)
+ + xen : Support management of Xen virtualisation (app-emulation/xen) |
Any idea how to solve that issue ?
Thks for your attention.

After a little thinking my guess I that what I'm trying to do is out of scope of the virt-manager+libvirt concept.
I guess I expected a ssh connection to domU where it should be a connection to dom0  .
My bad, it's so often like this. first I do the action, then the thinking only afterward.
Maybe I will change one day. At least in my next life I guess  . |
