Do you know what the changeset it?  This has been bugging me for a
while -- every now and again (just to taunt me) I get an absolute
pointer.
It's in the qemu code, so you may need to explicitly make sure that has
been updated: "cd tools/ioemu-remote; git pull".

Jeremy,

Do you know if this will be fixed in the Xen 3.4.x series as well? In the 3.4.x ioemu-remote qemu code and the 2.6.18.8 xen kernel?

I ask because this is an issue for me on RHEL5 domU's which are paravirtualized. Using Xen 3.4.3 w/ Xen kernel 2.6.18.8 and I'm not yet ready to switch production clusters to 4.0.x.

RHEL/CentOS5 deliberately avoids using the absolute pointer mode for reasons I don't understand, so it is broken as expected.

    J
