Ballooning does work for HVM domains. I applied Alex Bligh's patch
(http://blog.alex.org.uk/archives/23) to the stock Ubuntu 10.04 64-bit
kernel and was able to balloon up and down. There does seem to be an
accounting bug that I am debugging. The check you are talking about is of
course not present. It would be a shame if the upstream driver had that
check :(
Thanks,
AP
