HVM bug: system crashes after offline online a vcpu
Hi Konrad
I encountered a bug when trying to bring offline a cpu then online it
again in HVM. As I''m not very familiar with HVM stuffs I cannot come up
with a quick fix.
The HVM DomU is configured with 4 vcpus. After booting into command
prompt, I do following operations.
# echo 0 > /sys/devices/system/cpu/cpu3/online
# echo 1 > /sys/devices/system/cpu/cpu3/online

[PATCH v3 1/2] xen: enter/exit lazy_mmu_mode around m2p_override calls
This patch is a significant performance improvement for the
m2p_override: about 6% using the gntdev device.
Each m2p_add/remove_override call issues a MULTI_grant_table_op and a
__flush_tlb_single if kmap_op != NULL. Batching all the calls together
is a great performance benefit because it means issuing one hypercall
total rather than two hypercall per page.
If paravirt_lazy_mode is set
