Problem with Hugepages and Xen ?

March 3, 2011

When we enable the hugepages then kernel assures the hugepages, but when writes operation performed on it then kernel gets crashed. The reason is that there is no code in xen hypervisor which maps hugepages ptes of kernel. Also kernel can’t create its own pte without informing xen since page-tables in domain kernel are read-only.
