Dear KVM Subscribers: I am new to this list and to KVM, so please bear with me. I'm in search of documentation on how to configure virtual ethernet interfaces on guest VMs. In a CentOS 6.3 environment, after successfully installing my first KVM host machine, I've configured the following virtual ethernet interfaces on a guest VM to accommodate ip-based virtual hosts in Apache: eth0 = <private IP A> eth0:1 = <private IP B> eth0:2 = <private IP C> These private IPs are NATed at the firewall. Everything was working fine until my host was rebooted and I lost connectivity to the guest's three interfaces. I've read elsewhere that NetworkManager doesn't work well with KVM on the host, so I've stopped and disabled it in favor of network on the guest, too. Now, with NetworkManager out of the picture on the guest, a reboot no longer overwrites resolv.conf, as has been documented elsewhere. However, to get the guest's three interfaces back, I've found that I need to clear the guest's iptable cache, which isn't much of a solution. In retrospect, I'm wondering if I should switch to named-based virtual hosts in Apache and forget configuring virtual ethernet interfaces on a guest VM because it's not workable. Thanks, in advance, for your recommendations and patience.
