I'm intrigued as to where you got that syntax for corosync.conf from,
because it's nothing like what it should be :)

Try this (outside of the interface stanza).

nodelist {
    node {
        ring0_addr: 192.168.100.10
        nodeid: 10
    }

    node {
        ring0_addr: 192.168.100.20
        nodeid: 1
    }


man corosync.conf has more details
