Hello,I have problems to create ( xl create ... ) a PV domU with more than 460GB on a 512GB System. The domU crash with Unhandled invalid opcode fault/trap [#6, ec=0000] verry early while creating page-tables My own analyse shows that the crash happens in the first call of check_pt_base(...). (see hypervisor.log output from modified kernel) The earlier handled page tables (calls to set_page_prot_flags) are working.I tried it with different kernel 4.1.8 (12) 4.3.0 and different hypervisors 4.4 (ubuntu 14.04 LTS package) and 4.6.1-pre (git self compiled). The kernels are self compiled (git kernel source linux-stable/... ) and extended with aufs support (aufs4.x-rcN 20151102 for the 4.3.0 kernel) . Starting of domUs with reduced memory (> xl create ... memory="$((450*1024))") on startup and later resizing (> xl mem-set ... "$((489*1024))") to 489GB works.At this point I have no idear, because I am not familar with the kernel and hypervisor (page table) memory management. I hop the information helps. If you nee further information please let me know. Thanks and best wishes Andreas > xl info: xl info host : s876d0cn09 release : 4.3.0-xenaufs4xrcn.sfb876-02+ version : #1 SMP Mon Nov 9 06:33:44 CET 2015 machine : x86_64 nr_cpus : 48 max_cpu_id : 239

To find a solution my self I modified
.../xen/enlighten.c .../xen/mmu.c and .../xen/setup.c
adding some xen_raw_printk
replacing HYPERVISOR_update_va_mapping in mmu.c by
HYPERVISOR_update_va_mapping_ag
HYPERVISOR_update_va_mapping_ag is copy from the header file extended
with some xen_raw_printk calls
If I use the modified kernel I have the same Problem but with the following messages in hypervisor.log > xl create ....
