![]() ![]() In this case, a MAC address pool will not automatically use duplicate MAC address, only that a user can manually use a duplicate MAC address as required. If there are multiple MAC address ranges, with available MAC addresses, defined in a single MAC address pool, the ranges take turns serving incoming requests in the same way available MAC addresses are selected.Ī MAC address pool can be configured to allow manual assigning of duplicates. ![]() If the cluster has run out of MAC addresses to assign from the range, the search starts again from the beginning of range to check if any address is available. The assignment of new MAC address is from the next available address following the last assigned address in the pool. This helps with the prevention of MAC address duplication. When a new virtual network device is created, oVirt will automatically generate and assign Mac address to it. How MAC addresses are assigned in RHEV / oVirt If in your setup you have clusters sharing physical networks, it is not recommended to also share address pool since each cluster will be unaware of the addresses assigned by the other clusters, and this could result in conflicting MAC address assignments. The MAC address pool created by oVirt / RHEV installation is used for each cluster, unless you manually create an extra mac address pool and assign to a cluster. The same MAC address pool can contain multiple address ranges and is shareable by multiple clusters. As a default setting, each cluster has only one MAC address pool configured. ![]() Each cluster in RHEV virtualization environment has a MAC address pool which defines a range of MAC addresses allocated to the cluster. It has hyper-converged infrastructure design philosophy to enable you manage storage, compute and networking from a single administration portal. OVirt / RHEV is a powerful open source virtualization platform suitable for small to large enterprise infrastructure. ![]()
