Re: [libvirt] [PATCH 1/6] libxl: Fix handling of timeouts

xen-unstable commit XXXX makes changes wrt modifying and deregistering timeouts. First, timeout modify callbacks will only be invoked with an abs_t of {0,0}, i.e. make the timeout fire immediately. Prior to this commit, timeout modify callbacks were never invoked. Second, timeout deregister hooks will no longer be called. This patch makes changes in the libvirt libxl driver that should be compatible before and after commit XXXX. While at it, fix a potential overflow in the timeout register callback. --- 'commit XXXX' will be replaced with a proper commit id once committed to xen-unstable.
