VM powers off automatically after starting up
Description A VM configured with a VF shuts down shortly after powering on. This behavior is
observed when all available interrupt vectors on the host have been consumed. No
additional VMs with VFs attached will be able to startup successfully. The following entry
in the vmkernel.log will be logged when this occurs.
WARNING: IntrVector: 233: Out of interrupt vectors
Workaround/Solution To resolve this issue, reconfigure the VM and remove the VF, and then complete either of
the following procedures:
Move the VM to a different host also configured for SR-IOV.
Power off a different VM that has a VF attached, and then restart the offending VM.
Certain ProLiant servers do not provide required functionality for SR-IOV in all PCIe slots
Description The PCIe slots noted for the following servers do not support Access Control Services
(ACS) and
Alternative Requester ID Interpretation (ARI) functions. If you need advanced SR-IOV
functionality, do not install the PCIe network adapter to be used with SR-IOV in the
following slots:
• HP ProLiant DL360e Gen8 Server: Slot 2
• HP ProLiant DL380e Gen8 Server: Slot 4
• HP ProLiant DL380p Gen8 Server: Slot 3
• HP ProLiant DL560 Gen8 Server: Slot 3
• HP ProLiant ML350e Gen8 Server: Slot 5 and Slot 6
• HP ProLiant ML350p Gen8 Server: Slot 5
Workaround/Solution Use an alternate slot on the server for the network adapter.
