This happens even when there is paged-out memory from other guests to be had, and the system is not out of RAM for paging in guest's memory.
It seems like a page-in error on gfn 100, but that is strange as, from I what I gathered from the xenpaging code, policy_default.c starts paging only after half of the guest's gfns : current_gfn = max_pages / 2 (inside policy_default.c: policy_init())
I was expecting there to be other stability issues rather that this kind of an error.
Could someone please help me understand this and let me know if I am doing something incorrectly.
Also, there do not seem to be any interesting messages in xm dmesg or in /var/log/xen*.
