Hello,
I have tried installing on server Dell PowerEdge T130:
1. vCenter Appliance 6.5.0 U1g, Date: 2018-03-20 (VMware-VCSA-all-6.5.0-8024368) with ESXi 6.5 U1 A10, Date: 03 Apr 2018 (VMware-VMvisor-Installer-6.5.0.update01-7967591.x86_64-DellEMC_Customized-A10.iso)
2. vCenter Appliance 6.7 (VMware-VCSA-all-6.7.0-8217866.iso) with ESXi 6.7 A01, 23 Apr 2018 (VMware-VMvisor-Installer-6.7.0-8169922.x86_64-DellEMC_Customized-A01.iso),
in both installation (1. and 2.), it stuck in x% in stage 2, where installation is configuring vCenter on machine (RPM installation).
The installer log report I've at attached to this post.
From this thread https://communities.vmware.com/message/2738172#2738172
is seems that is has to do something with FQDN, but evey time I leave it blank and it fill it self with provided IP address.
You must use the FQDN as well as valid internal ntp when installing. An IP cannot be used in place of FQDN.
