[Xen-devel] [RFC] [PATCH] HVM SMBIOS support 0/6

  • To: xen-devel@xxxxxxxxxxxxxxxxxxx

This series of patches adds support for SMBIOS to HVM domU's.  This is
needed by many systems management applications, most often to get a
useful UUID inside of an HVM domU.

They have been tested on changeset
of xen-unstable.

Any comments or help would be greatly appreciated.
