Hi Tomáš,

virsh list --all works locally and results in list of all VMs.

virsh -c xen+ssh://root@192.168.1.40 results in two errors:

error: failed to connect to hypervisor
error: End of file while reading data: : Input/output error

--

Thanks & Regards,

Anantha Raghava

Hi,

Tested this with different combinations:

a. from VDSM host, both "ssh root@192.168.1.40" and "sudo -u vdsm ssh
root@192.168.1.40" commands are logging in without asking for password
and I can run all xe commands without any glitch without modifications
to default xen server firewall or SELinux rules.
Could you please verify that running 'virsh list --all' localy works too?


b. With firewall enabled and SELinux set to enforcing or permissive or
disabled, I run "virsh -c ssh://root@192.168.1.40". And the command is
resulting in two errors:

      error: filed to connect to the hypervisor
      error: unable to connect to the server at '192.168.1.40:16514' : No
route to the host.

c. With firewall disabled and SELinux set to Enforcing or permissive or
disabled, I run "virsh -c ssh://192.168.1.40". And the command is
resulting in two errors

error: filed to connect to the hypervisor
      error: unable to connect to the server at '192.168.1.40:16514' :
Connection refused

That is because your libvirt URI is wrong. It has to be 'xen+ssh://...'
not 'ssh://...'.

Does it work if you try: virsh -c 'xen+ssh://root@192.168.1.40'

Best regards,

     Tomas
