it works in my side, due to config difference. It is caused by recent
steal time feature.
int kvm_set_msr_common(struct kvm_vcpu *vcpu, u32 msr, u64 data)
case MSR_KVM_STEAL_TIME:
if (unlikely(!sched_info_on()))
return 1;
static inline int sched_info_on(void)
{
#ifdef CONFIG_SCHEDSTATS
return 1;
#elif defined(CONFIG_TASK_DELAY_ACCT)
extern int delayacct_on;
return delayacct_on;
#else
return 0;
#endif
}
I have CONFIG_SCHEDSTATS enabled, while yours has CONFIG_SCHEDSTATS
as 'n' while "CONFIG_TASK_DELAY_ACCT) as 'y'. However delayacct_on is
not an exposed symbol to modules.
Thanks
