...and tested with the 3.0.4 era hypervisor that ships with SLES 10, and then ported and tested on current xen-unstable. The Linux patch was written and tested on 2.6.16 and made apply to the 2.6.18 tree without further testing. Feedback and comments are appreciated.

I just noticed that the linux block backend does not copy the full 64 bits of the id field of a request to the associated response. The blkif.h states that this is echoed in the response. An unsigned long in make_response is used as an intermediary. This would sure be helpful to me if the full 64 bits were echoed. - Bruce Rogers _______________________________________________ Xen-devel

The paravirtualized guests are offered wallclock time referenced to UTC only, while fully virtualized guests are given the option via the config file (localtime parameter) of starting with UTC time or local time. What would it take to optionally provide localtime to the paravirtualized guests as well? For a guest that launches assuming localtime as its time basis, then later deriving UTC from it

...this when I was reviewing what was outstanding to get NetWare to run fully virtualized. The BIOS emulator code has the segment and offset backward in the returned buffer for the int 13h, fn 48h BIOS call. BTW: This is fixed in current Bochs emulator upstream code.

My apologies to the list, as the last patch was not correct. It did no harm, but was to the trailing comma on the structure above the enum I was targeting. This patch is correct.

...ord to this include information, and to process that information.

...as previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.
