Environment

7.x

Cause

ESXi hosts are connected to vCenter with short DNS name.
According to the glance-api log, the glance api pod cannot setup connection to https://esxi1

Resolution

Check DNS resolution in vCenter specifying IP of your DNS server.

Example if DNS server ip 192.168.0.1

# dig +short @192.168.0.1 esxi1.example.com
192.168.0.2
# dig +short @192.168.0.1 esxi1
No DNS record.

Workaround:

• Reconnect ESXi hosts with FQDN instead of a short name.
• Verify routing on VIO controllers so that you can ping ESXi hosts in the cluster.
