Indeed, thre is no SMBios data made available to ParaVirt guests so it is
not currently possible to make dmidecide work for PV guests. This may change
in the future, but I don't think anyone is actively working on SMBios support
for PV just yet.
Best to file a bug report about this denial of service in bugzilla.
