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

These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its
