4.6.3 Interrupt migration of vNICs during Online guest migration can result in network
disconnectivity
During Online migration of guest, if interrupt migration of vNIC is performed, there may be network
disruption at the destination VSP. To avoid this issue, interrupt migration must not be performed
during Online guest migration.
4.6.4 Physical NIC link state change during hpvmsuspend to hpvmresume may
result vNIC in down state
While suspending the guest, if a physical NIC backing to a vSwitch has a Link in Up state and if
that goes to Down state before resuming the guest using the hpvmresume command, then the
associated vNICs of that guest may be in Down state.
Workaround
Reset the backing interface to get the exact interface status.
NOTE: During the reset of the physical interface there can be very negligible amount of packet
drops.
4.6.5 Offline migration of a guest- with multiple DIO resources might succeed with
errors if the DIO devices are added under the same label
For a vPar or VM guest configured with multiple DIO devices having the same label, offline
migrations may intermittently succeed with error messages.
Before migration multiple DIO device with same label on source:
# hpvmhwmgmt -p dio -l
H/W Path Class Owner Assignment Level Label
