Betreff: [PATCH] kvm-s390: Fix kvm on IBM System z10
Datum: Dienstag, 29. Juli 2008
Von: Christian Borntraeger <[EMAIL PROTECTED]>
An: Avi Kivity <[EMAIL PROTECTED]>
From: Christian Borntraeger <[EMAIL PROTECTED]>
The z10 system supports large pages, kvm-s390 doesnt.
Make sure that we dont advertise large pages to avoid the guest crashing as
soon as the guest kernel activates DAT.
Avi, this should go into 2.6.27-rc*.
