I'm trying to use ballooning with kvm-83.
Although I'm able to limit the guest's memory, when I try to increase it right after that, I get "vballoon: page allocation failure. order:0" followed by a kernel panic.
Is it expected?
The guest is running Debian Lenny with 2.6.26 kernel. It had initially 256 MB memory.
I used:
qm> balloon 200
qm> balloon 220
in Qemu monitor.
