I was running some tests of HVM guests on Fedora Core 6, test3 and came
across a potential issue with SMBIOS data. When running dmidecode in the
guest VMs it reports that the actual SMBIOS data size, does not match
the advertised size. eg
"Wrong DMI structures length: 439 bytes announced, structures occupy 363 bytes."
I've tried this in a variety of guest OS (RHEL-3 32-bit, RHEL-3 64-bit,
RHEL-4 64-bit) all the same results. The host is running FC6 test3, but
the bit of code responsible for constructing the SMBIOS tables is identical
to that on the vanilla xen-unstable.hg repository. I'm not familiar 
enough with SMBIOS specs / code to determine where the mistake in the
length calculation is though...
Is anyone else seeing this length mismatch in HVM guests ?
FYI, we're tracking this as 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=207501
Regards,
Dan.
