Issue 1:
While trying to add a new host to a Pool in XenCenter, I was getting error "internal connection failed no route to host "
Solution:
It was quite simple actually, but since I couldnt find it mentioned in any knowledge bases or articles, I am noting it down here. The machine where XenCenter was installed couldnt resolve the Xen host name. The machines were not added to domains and hence no DNS entries were there. So I had to add a host entry to the XenCenter machine to help with the name resolution
Issue 2:
Enabling AD authentication via XenCenter fails with error "clock skew detected with active directory server"
Reason:
This happens because of the time difference between XenServer and AD server
Solution:
Update NTP server list of the XenServer and point it to the AD server of the domain. Steps below
From the XenServer console, go to 'Network and management interface"->Network time(NTP)
Select option "Remove all NTP servers" to remove the default NTP server configuration
Then select option "Add an NTP server"
Enter the name or IP address of the NTP server
This will update the NTP configuration. On the same menu, click on 'Enable NTP time synchronization" to complete the configuration
