“xm save” falha no kernel.org domU com o Xen 3.4.1

Question

Eu instalei o Xen 3.4.1 da fonte. Algumas das minhas paravirtas domUs usam o kernel oficial do XenLinux (2.6.18) e algumas usam o mainline kernel.org.

Quando eu executo "xm save" nos convidados do kernel.org, o comando "xm save" trava onde é executado no dom0, e no console do domU eu recebo um erro:

PM: Device rtc_cmos failed to suspend: error -22
xen suspend: dpm_suspend_start -22

Estou usando a versão 2.6.31.4 do kernel para o domU, que construímos a partir do código-fonte (os domUs do XenLinux são suspensos sem problemas).

Isso é um bug ou estou fazendo algo errado?

Aqui está o arquivo de configuração do Xen para o domU em questão:

#
# Configuration file for the Xen instance lit, created
# by xen-tools 4.1 on Sat Jul 25 11:01:31 2009.
#

#
#  Kernel + memory size
#
kernel      = '/opt/xen/linux-2.6.31.4/vmlinuz'
memory      = '128'

#
#  Disk device(s).
#
root        = '/dev/xvda2 ro'
disk        = [
                 'phy:/dev/vg00/lit-disk,xvda2,w',
                 'phy:/dev/vg00/lit-swap,xvda1,w',
             ]

#
#  Hostname
#

#
#  Networking
#
vif         = [ 'ip=192.168.1.28,mac=00:16:3E:9A:C1:8B' ]

#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

extra='console=hvc0' 

E aqui está o arquivo .config para construir o kernel domU:

Answer 1

Você não diz qual distro está usando. Eu me pergunto por que você não usa uma distro como o OpenSUSE que vem com o XEN embutido e configurado?

Eu diria que é aí que você está errado. Instalar o código-fonte e o patching é bom se você for um desenvolvedor, mas para construir servidores para fazer o trabalho real, é melhor ficar com um dsitro que suporte o XEN.

Ou, se você tiver a flexibilidade de escolher algo diferente do Linux, o OpenSolaris também terá o XEN incluído nas distribuições mais recentes.

    

Answer 2

O mesmo problema aqui com a migração ao vivo:

Dom0: Xenserver 5.5, Kernel 2.6.18

DomU: Gentoo, Kernel 2.6.31-r7 ( code.google.com/p/ gentoo-xen-kernel / )

Saída do DOMU dmesg:

PM: Device rtc_cmos failed to suspend late: error -22
dpm_suspend_noirq() failed: -22
Xen suspend failed (-22)

Answer 3

Você já tentou desabilitar a ACPI no domU?

    

Answer 4

Estou tendo um problema parecido com o Xen 3.1 e o Xen 3.0.3 com um DomU executando o 2.6.31.6 (vanilla do kernel.org). No Xen 3.3, o problema não aparece, então estou surpreso em vê-lo retornar com o Xen 3.4.1.

Estou tentando depurar este para ver qual chamada do kernel está falhando.

ATUALIZAÇÃO 12/10/2009: Entrei em contato com Jeremy Fitzhardinge sobre o assunto, já que ele é um dos caras que escreveu muitos patches para a atual árvore do kernel relacionada a pv_ops. Ele disse:

There are a number of bugs with save/restore in vanilla Linux at the moment. I've submitted fixes for them, but I don't think they've been picked up yet. In the mean time, I recommend using the xen.git kernel.

Ele está se referindo ao seu repositório git aqui: link

Eu criei um kernel a partir de seus últimos commits (agora é 2.6.31.6) e posso usar xm save sem nenhum problema. No entanto, quando tento usar xm restore , há um grande problema de rede. Executar qualquer coisa relacionada à rede (como ifconfig ) faz com que toda a domU seja bloqueada.

Não deixe de conferir este tópico da lista de discussão do xen-devel: link . Ele contém muita informação boa.
