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. moodle1:~# free total used free shared buffers cached Mem: 256584 43816 212768 0 2956 25640 -/+ buffers/cache: 15220 241364 Swap: 0 0 0 moodle1:~# free total used free shared buffers cached Mem: 199240 43712 155528 0 2956 25640 -/+ buffers/cache: 15116 184124 Swap: 0 0 0 moodle1:~# [ 87.268105] vballoon: page allocation failure. order:0, mode:0x210d2 [ 87.271481] Pid: 1165, comm: vballoon Not tainted 2.6.26-1-486 #1 [ 87.275299] [<c014ecab>] __alloc_pages_internal+0x318/0x32c [ 87.280857] [<c014eccb>] __alloc_pages+0x7/0x9 [ 87.283704] [<d082b2c4>] balloon+0x11d/0x1ec [virtio_balloon] [ 87.287396] [<c012990b>] autoremove_wake_function+0x0/0x2d [ 87.290981] [<d082b1a7>] balloon+0x0/0x1ec [virtio_balloon] [ 87.294587] [<c0129763>] kthread+0x36/0x5b [ 87.296586] [<c012972d>] kthread+0x0/0x5b [ 87.299292] [<c0104937>] kernel_thread_helper+0x7/0x10 [ 87.302704] ======================= [ 87.305000] Mem-info: [ 87.306478] DMA per-cpu: [ 87.308151] CPU 0: hi: 0, btch: 1 usd: 0 [ 87.311225] Normal per-cpu: [ 87.313013] CPU 0: hi: 90, btch: 15 usd: 76 [ 87.316088] Active:1996 inactive:47 dirty:0 writeback:0 unstable:0 [ 87.316090] free:737 slab:929 mapped:1 pagetables:130 bounce:0 [ 87.323723] DMA free:1076kB min:124kB low:152kB high:184kB active:0kB inactive:0kB present:16256kB pages_scanned:0 all_unreclaimable? yes [ 87.331290] lowmem_reserve[]: 0 238 238 [ 87.334476] Normal free:1872kB min:1908kB low:2384kB high:2860kB active:7984kB inactive:188kB present:243776kB pages_scanned:17871 all_unreclaimable? yes [ 87.342884] lowmem_reserve[]: 0 0 0 [ 87.345004] DMA: 1*4kB 0*8kB 1*16kB 1*32kB 0*64kB 0*128kB 0*256kB 0*512kB 1*1024kB 0*2048kB 0*4096kB = 1076kB [ 87.351565] Normal: 0*4kB 0*8kB 1*16kB 0*32kB 1*64kB 0*128kB 1*256kB 1*512kB 1*1024kB 0*2048kB 0*4096kB = 1872kB [ 87.358302] 47 total pagecache pages [ 87.360053] Swap cache: add 0, delete 0, find 0/0 [ 87.363034] Free swap = 0kB [ 87.364844] Total swap = 0kB [ 87.368045] 65520 pages of RAM [ 87.370171] 0 pages of HIGHMEM [ 87.372136] 1374 reserved pages [ 87.374153] 4746 pages shared [ 87.376008] 0 pages swap cached [ 87.378020] 0 pages dirty [ 87.379643] 0 pages writeback [ 87.381565] 1 pages mapped [ 87.383305] 929 pages slab [ 87.384315] 130 pages pagetables [ 87.385187] virtio_balloon virtio3: Out of puff!
