What specifically doesn't work with HostAP?

Who can't ping? If it's the dhcp client then you may not be supplying
What can't you ping, an IP address or a DNS name?

How is this a HostAP issue?

You haven't told dhcpd which devices to use so it's trying to use ALL

This is a virtual device which shouldn't be used for serving dhcp addresses.

This should be self-explanatory. Write a subnet declaration for eth0.

In the absence of more debug information I'd say HostAP worked.
This isn't a HostAP issue. It's a dhcpd configuration issue.
Since you didn't specify which flavor of Linux you're running I'll assume
it's RedHat. Furthermore, since you didn't specify what you were trying
to accomplish, I'll assume you wanted to serve, using dhcpd, an address
pool on wlan0. The simple answer to this dilemma is to add
"DHCPDARGS=wlan0" to /etc/sysconfig/dhcpd. The complete answer to this
issue is to consult your dhcp server documentation.
