I did the same test, I obtain the same result but here is what I get into the /var/log/messages guest (7.1) logs and not mentionned there:
unsupported configuration: maxMemory has to be specified when using memory devices
What can't I do with this error, is it a known issue?

In my case I only got the line I wrote in previous e-mail when I click ok in web gui to increase memory:

Dec 9 23:56:18 racclient1 kernel: init_memory_mapping: [mem 0x240000000-0x2bfffffff]

See here the messages boot related lines for my guest, just before I tried to increase memory, in case they can be useful:

BTW: Nathanaël did you increase by 256Mb multiples? I see this is a sort of limitation... what was previous amount of ram of VM and the tried new setting?
