Configuring vSwitch following a S10U4 (08/07) upgrade
By narayan on Sep 27, 2007
In order to enable networking between the domains and the service domain, the LDoms 1.0 Admin guide (pg 42) recommends users to unplumb the physical adapter; and plumb the vSwitch instead. In order for this to function correctly, the LDoms vSwitch will need to be assigned the same MAC address as that of the physical adapter. This workaround is only necessary when the vSwitch is plumbed as a network device, and enable it to receive packets from the external network. A patch to address this issue is in the works and will be released soon.
The issue is also documented in the LDoms 1.0.1 release notes.
