Commit 095497ffc66b7f031ff2a17f1e50f5cb105ce588 ("vnc-enc-tight: use
thread local storage for palette") introduced a regression with Xen:
Since this commit qemu used as a device model is no longer capable
to register Xenstore watches (that's the effect visible to a user).
Reverting this commit makes qemu behave well again. I have no idea
why that commit would have this effect with Xen, may be some memory
is clobbered?Juergen
