Hello Andrew,
firstly, thank you for your answer. We have some software being moved
from physical machines to virtual machines and we need to maintain those
UUID's. I've been able to change the hvmloader to staticly change the
UUID. It seems that xenstore uses fixed database scheme, so I guess I
would first have to request a change in that scheme to also make it
possible to specify product-uuid or similar in bios-strings and than it
would be fairly trivial to use xenstore_* functions to get this and use
it if specified.
If I understand this correctly, xenstore is under XAPI development? I
can also provide the patch fro hvmloader to use this new xenstore
propery in bios-strings.
It's fairly easy to change this in vmWare or HyperV.
Thank you and kind regards,
Dejan

Hello all,
sorry, as this might be a stupid question for some of you, but I
wonder why here:

You allow almost everything to be overwritten in SMBIOS type 1 table
except the UUID.
Probably only because whomever implemented the code didn't need to do that.
Would there be any problems if UUID was also picked up from xenstore
with, for instance, HVM_XS_SYSTEM_UUID?
The UUID is currently picked up from the domain's UUID stored in Xen, so
is currently under toolstack control.
I don't see a particular problem with being able to specify it via
xenstore. What is your usecase here?
