The following is an example of a configuration for an Oracle VM environment in the case of using the NIC switching mode in Solaris 10 environment.
In the system below, virtual switches "primary-vsw0" and "primary-vsw1" are configured by using physical NICs "e1000g0" and "e1000g1" on the control domain. The virtual network devices "vnet0" and "vnet1" generated on the virtual switches are used on guest domains.
On each domain, GLS multiplexes the virtual devices to configure the virtual interface sha0. For the virtual NIC to be multiplexed, "vsw0" and "vsw1" are specified on the control domain, and "vnet0" and "vnet1" are specified on guest domains.
For configurations using the NIC switching mode, the applications for each domain will perform data transmission using the virtual device ("vsw0" or "vnet0") multiplexed with the NIC switching mode. If an error occurs in the transfer path for the virtual device multiplexed with the NIC switching mode, since the IP address being used with each domain will be taken over from the active interface (vsw0, vnet0) to the standby interface (vsw1, vnet1), the applications on each domain will be able to continue transmission.
Information
When multiplexing the virtual networks (vsw and vnet) with the NIC switching mode in Oracle VM environments, specify 0:0:0:0:0:0 to the MAC address of the standby patrol. Therefore, the virtual MAC address generated by Oracle VM with the standby patrol function will be used.
To configure the cluster system environment of Redundant Line Control function in Oracle VM environments, see "Using PRIMECLUSTER in Oracle VM Server for SPARC Environments" in "PRIMECLUSTER Installation and Administration Guide."
For the HUB monitoring destination, set up items such as the switches outside of the domain. If one has set those within the domain for monitoring, even if there is a malfunction with the physical interface comprising the virtual switches, the malfunction may not be detectable.
