I tried maxmem on some domU with xl, pv domU start, qemu-xen-traditional domU also, same domU with qemu upstream not. Qemu start but not on screen show boot devide not found (but there are and working), nothing on log, seem to be ram allocation bug or unexpected cases on xen and/or seabios. Dom0 is Wheezy 64 bitwith kernel 3.2.0-1-amd64 version 3.2.6-1 and xen-unstable from source changeset 24967:33659563f589. Thanks for any reply and sorry for bad english. -- View this message in context: http://xen.1045712.n5.nabble.com/Xen-unstable-maxmem-broke-domU-start-with-qemu-upstream-tp5546868p5546868.html Sent from the Xen - Dev mailing list archive at Nabble.com.
