I also had this issue with IPv6, but it had been fixed a time ago.
After this commit, I have working IPv6 in vultr.

    virtio: Bring in SVN r251769 from FreeBSD.

    * Fixes the following occasional log message when booting:
    "vtnet0: error setting host MAC filter table"

    * Original FreeBSD commit message below.

    QEMU 1.4 made the descriptor requirement stricter - the size of buffer
    descriptor must exactly match the number of MAC addresses provided.
