Not working DNS resolver how to set or check?

Try to configure virtualization on the server SoyouStart (OVH) - everything seems set up correctly but does not work resolve addresses. Ping as I understand it from the new path to the Internet, and the virtual machine pinged. FAILOVER_IP - ip address for the virtual machine.
ping -c 2 (0% packet loss, time 1001ms)

ping -c 2
ping: unknown host

Try to ping the address of a path from the desktop computer - seems to work.
To connect to virtual reality via SSH without timeout.
ping -c 2 FAILOVER_IP (0% packet loss, time 1001ms)
debug1: Connecting to FAILOVER_IP [FAILOVER_IP] port 22 (stops)

DNS for ovh vitrually of the path ping and the host machine too. dns nameservers are registered and available.
ping -c 2

Go through the web console and see that there inclucapa and firewall rules
SoyouStart - there is no such. Install a clean/default.
view to there with nslookup and firewall rules

And what commands must be entered and what should show? - yvonne75 commented on June 8th 19 at 16:31
iptables-L on the dev - everything is open (policy ACCEPT) - yvonne75 commented on June 8th 19 at 16:34
well nslookup domain
ustart based on OVH, and OVH is a web console and probably ustart must also be - Eulalia22 commented on June 8th 19 at 16:37
, nslookup,...;; connection timed out; no servers could be reached - yvonne75 commented on June 8th 19 at 16:40
where you something nakosyachili
the easiest way to rearrange the system
harder to get an admin to have it figured out - Eulalia22 commented on June 8th 19 at 16:43
I use Ansible - that is, in parallel with another hoster (online) all make a half-turn - all actions are identical. I would hire a admin, if he does and explain what's wrong, where to find it? - yvonne75 commented on June 8th 19 at 16:46
there plugging in ipitables host machine. What IPTABLES rule prevents the new path? - yvonne75 commented on June 8th 19 at 16:49
