Can you ping by ip but not name? If so check your /etc/resolv.conf
file. It's probably missing the DNS servers. I found that when I
installed hosted-engine deployment the first phase of setup (before
creating the engine VM) did not copy over the DNS settings from my
original NIC interface so the deployment leaves an empty resolv.conf
file and the host can't find the engine and vice versa. I added the
DNS servers to the ifcfg-ovirtmgmt file (DNS1=xxx.xxx.xxx.xxx) and did
a systemctl restart network and it worked. Unfortunately if you tried
to install the Engine VM, told the deployment it's okay the whole thing
fails on the last step because the host can't find the engine. There
are some bugs filed on it.
