[Dnsmasq-discuss] Dnsmasq 2.68 not assign IPv6 address, error -- no addresses available

[Da Zhao Y Yu]

Hi Simon,

I remember in KVM env, use the earlier version of dnsmasq, the client can 
got the target IP address.

Today, in order to recheck it, In one new KVM env, I use dnsmasq 2.68, and 
found we still need wrap the IPv6 address with "[]" in host file.

Ah, yes. That would explain it. Sorry I didn't spot that. The reason for 
the [] is to allow dnsmasq is distinguish MAC addresses from IPv6 
addresses.

Does kvm add the braces itself?
