Running with Xen option dom0_mem=6G and kernel option mem=8G, I would have expected that I would see the system with a 2G balloon right after boot. However, the balloon is empty. Briefly looking at this, it would seem to me that, with all pages being reserved when the system starts and only the populated ones getting the reserved status cleared in __free_pages_bootmem(), the condition to put pages

Hi all. I am trying to debug a kernel that I built, and I hope I could see some debug info printing out via XENPRINTF. I use it in the source code of kernel like: XENPRINTF("nr_pages: %ld shared_info: 0x%lx flags: 0x%lx pt_base: 0x%lx " "mod_start: 0x%lx mod_len: 0x%lx\n", xen_start_info->nr_pages, xen_start_info->shared_info, xen_start_info->flags, xen_start_info->pt_base, xen_start_info->mod_start, xen_start_info->mod_len);...

Hi, All Intel QA conducted a full validation for xen 4.1 rc1, it includes VT-x, VT-d, SRIOV, RAS, TXT and xl tools testing. 24 issues were exposed. Refer the bug list, please. We already assigned 14 bugs to Intel developers (which has an ''Intel'' tag in the bug title), most of the rest 10 bugs are related xl command. For the these bugs, need community''s help to fix

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
