Subject: [Qemu-devel] [PATCH v3 0/2] Fix real mode guest live migration
Date: Mon, 22 Jul 2013 20:29:40 +0300 [thread overview]
Message-ID: <1374514182-24808-1-git-send-email-owasserm@redhat.com> (raw)
Older KVM versions save CS dpl value to an invalid value for real mode guests
(0x3). This caused migration to fail from older KVM on host without unrestricted guest to hosts with restricted guest support with "kvm: unhandled exit 80000021".
For example migration from a Penryn host (with kernel 2.6.32) to
a Westmere host (for real mode guest)
This series fixing it both in the destination and source QEMU.
Changes from v2:
Fix more typos
Changes from v1:
Fix typos and style
Orit Wasserman (2):
Fix real mode guest migration
Fix real mode guest segments dpl value in savevm
