--- Comment #10 from Jan Beulich
Thanks for looking into this. I am still wondering, though, why it doesn't work even when the flag is ON
Which "the flag"? You said you run on 4.0, and I turning on xsave support in that hypervisor is, hmm, adventurous (depending on how many post-4.0 patches you have backported).
and recognized by the PV OPS kernel. Looking at
I generally can't comment on the pv-ops kernel (and in particular, as none of our products contains one, here - this would be better discussed on e.g. xen-devel).
the kernel code, it seems that there is code to handle the XSAVEOPT capability. Why is that we get a page for the fpu.state whose PTE is 0? And why wouldn't this problem happen all the time. It is very sporadic for us as to when it happens...
As said originally - perhaps just a dangling pointer that once in a while refers to a page ballooned out of Dom0. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
