The version update in vmstate_ps2_common might not be needed, IIRC the versions for stuff referenced via VMSTATE_STRUCT() isn't used anyway, Juan? cheers, Gerd

Yeah, I somehow updated the field in the wrong struct, /me blushes and hides. I don't think this struct version needs to be updated. > The version update in vmstate_ps2_common might not be needed, IIRC > the versions for stuff referenced via VMSTATE_STRUCT() isn't used > anyway, Juan? Ah, ok, I hoped it would help to handle migration between versions with and without this field, I guess I was too optimistic :) Thanks, Christophe

Make the ps2 device track its ledstate so that we can migrate it. Otherwise it gets lost across migration, and spice-server gets confused about the actual keyboard state and sends bogus caps/scroll/num key events. This fixes RH bug #729294 Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> --- v3: use VMSTATE_UINT32_V to indicate the ledstate field was added in version_id == 4 --- hw/ps2.c | 15 ++++++++++++--- 1 files changed, 12 insertions(+), 3 deletions(-)
