Re: approach for heavily hw-oriented values in smbios for guests

["Andrew D. Ball" <aball@linux.vnet.ibm.com>]

As far as I know, SMBIOS data reflects the state of the system at boot
time only.  No updates after any sort of hot-plugging.  However, I
distantly remember some possibility of updating something, maybe a power
state.

However, the format of the data is so fixed, that dynamic updates, like
adding vCPUs are infeasible.

Peace.
