[Qemu-devel] Xen: qemu dies with xen-all.c:478: xen_log_sync: Assertion `r >= 0' failed.

[Julian Pidancet]

When testing the latest master branch, qemu dies with the above error
message. The issue seems to have been introduced by the following
recent patch:

xen: convert to MemoryListener API (20581d207853fe4b1af88b116f077516dfa888cd)

Commenting the assert() prevents qemu from dying, but there may be
another underlying problem with framebuffer dirty page tracking
because the display is really slow on my setup (It wasn't the last
time I tried).
