Re: page allocation failure

Thanks! I'll try a new kernel. Interestingly two guests with 2.6.32-r3 (Gentoo naming not rc3) with much more NFS traffic don't show this behavior of 2.6.32-r5. So I'll try 2.6.32-r8. I've found some threads with NFS and kernel 2.6.32.x related problems which seems to be fixed in later versions. -

vballoon: page allocation failure. order:0 -> Kernel panic

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 w
