A summary of my testing from last week: * 3.17-rc4 (with qemu 2.0) seems to have had the same problem as well. * Disabling ntpd didn't help either. * <timer name="kvmclock" present="no"/> _does_ seem to make my VM migrate without issue. I'm not really sure what to look at from here. I suppose leaving kvmclock disabled is a workaround for now, but is there a major disadvantage to doing so? -- 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
