I''ve just pushed a new MQ gate for the latest 3.3 qemu bits (http://xenbits.xensource.com/git-http/qemu-xen-3.3-testing). As of this putback, all qemu changes should be done out of qemu.hg and not xen.hg. The bits in qemu.hg represent a significant upgrade to qemu... Additional emulated devices including e1000 are now available. Other than ported upstream patches, there should not be any patches that we introduce which change anything in xen.hg/tools/ioemu (since those bits are 99% unused). building qemu is still done out of the xen.hg gate with build-xen (see xen.hg/.hg/patches/use-qemu.hg). As of now, we are now in sync with the latest 3.3.2-rc bits in the upstream gates. You can update up your gate properly with the following procedure. cd $XVM_WS/sunos.hg hg pull -uv cd $XVM_WS ./sunos.hg/bin/update-gate `pwd` ssh://anon@hg.opensolaris.org//hg/xen-gate/xvm-3.3+ Thanks, MRJ
