[pve-devel] [PATCH 3/4] pvecm create: add corosync.conf parameters for ipv6

[Wolfgang Bumiller]

pvecm create now adds the following additional corosync.conf parameters:
 * totem.ip_version
 * totem.interface.ringnumber
 * totem.interface.bindnetaddr

For ipv6 corosync needs a 'totem.interface' list with at least one entry
containing a bindnetaddr setting. Additionally 'totem.ip_version' needs to
explicitly be set to ipv6 (or an 'mcastaddr' set, which corosync can
choose automatically, though, so we let it do just that).
