Como depurar a interrupção de rede intermitente no Citrix XenServer

1

Eu tenho dois Citrix XenServers em um pool. Ambas possuem uma NIC para Gerenciamento, uma NIC para a SAN e uma NIC para as VMs se conectarem à rede. A NIC para as VMs (eth3) possui várias redes configuradas para as VMs com diferentes IDs de VLAN.

Isso vem funcionando bem por dois anos. Recentemente, comecei a receber ping pings para as várias VMs que estou monitorando.

Quando isso aconteceu, verifiquei imediatamente as VMs e não consegui ver nada funcionar. Por exemplo, uma dessas VM está executando o Windows 2008 e eu tive uma sessão RDP. Eu tenho o alerta e alt-tab'ed para a minha sessão RDP e estava tudo bem.

Uma vez, a interrupção durou vários minutos. Mas todas as outras 5-6 vezes nas últimas 3 semanas, a interrupção foi tão rápida que não pude verificar nada enquanto estava inoperante.

Eu tenho mensagens do software em execução em algumas dessas VMs que houve uma interrupção de rede - ou seja, o software em execução na VM1 não conseguiu se conectar ao banco de dados na VM2.

Eu olhei para o adaptador de rede VM1 no Windows e ele relata que há mais de 500 dias. Por isso, não houve um evento "link down".

Eu verifiquei meu comutador ao qual os XenServers estão conectados e não vejo nada lá.

Eu tenho o DVS Controller instalado (mas eu posso ter feito alguma configuração errada sobre isso - mas tem sido assim há 2 anos, então ...) e hoje eu notei que esta mensagem aparece pouco antes do tempo que recebo os alertas :

Established control channel for network on server 'xen1'

Então, eu recebo vários eventos, como:

'server1' now using IP 10.5.4.1 with interface 'mac-address'. 'server1' added interface 'mac-address' to network 'Vlan640' on server 'xen1'

Ele repete essas duas entradas para todas as VMs no xen1.

No host do XenServer, em / var / log / messages, eu encontro as seguintes linhas (existem mais, mas isso é o que parece relevante):
