Ewan, I didn't notice 514, but I submitted a related bug http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=3D549. It appears t= hat the big deciding factor on whether or not I see the race is is the DomU that is rebooting running on a fully independant CPU from Dom0. If it is, it breaks every time, if it isn't (i.e. it is on the *same* phys CPU as Dom0) it works every time. -Sean --=20 Sean Dague IBM Linux Technology Center email: japh@us.ibm.com Open Hypervisor Team alt: sldague@us.ibm.com --ew6BAiZeqk4r7MaW Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFEA02lSamXem9TdyYRAhEQAKCo3J5KcozB7jW3TOKZrkUTFsDJnACgg2wD hzReI5JxSapQ+Z8MR8ZHlCU= =YXNQ -----END PGP SIGNATURE----- --ew6BAiZeqk4r7MaW-- --===============1233501340== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel --===============1233501340==--
