I have made some experiments like you suggested. Migrating VM back to node where it worked fine does not help. I have found in VMs logs: Clocksource tsc unstable (delta = 123652847 ns) It was logged after first live migration but did not break VM. I continued to migrate it back and forth and after few migrations it broke like usual. Nothing more in logs. I was experimenting with clock source: http://liquidat.wordpress.com/2013/04/02/howto-fixing-unstable-clocksource-in-virtualised-centos/ It did not help. I have tried changing clock source manually but it still did not restore its functionality. regards -- Maciej Gałkiewicz Shelly Cloud Sp. z o. o., Sysadmin http://shellycloud.com/, macias@xxxxxxxxxxxxxxx KRS: 0000440358 REGON: 101504426 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
