For the balloon driver to work properly, it needs a correct E820 map and there have been recent upstream changes in the balloon driver involving E820. If we assume that your E820 map is indeed broken, the easiest fix for your machine might be just to modify balloon_init in dom0 to immediately fail (and return -ENODEV). Returning -ENODEV at the beginning of balloon_init() did allow the machine to boot, but something is definitely still amiss: Trying to start any domUs yields: simba@hailstorm:~$ sudo xm create test.cfg Using config file "/etc/xen/test.cfg". Error: Failed to query current memory allocation of dom0. Oddly enough, xencommons and xend started and xm list and xm info show everything correctly. And this is just bizarre... simba@hailstorm:~$ free total used free shared buffers cached Mem: 552 18014398509158460 324076 0 11428 34656 -/+ buffers/cache: 18014398509112376 370160 Swap: 0 0 0 I just tried grabbing the most recent BIOS revision from Tyan for this motherboard (was running 2882_306, flashed it to 2882_309).
