How to get to know vcpu status from outside

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Paolo,

Since VCPU is managed the same as a process in kernel, how can I know
the status (running, sleeping etc.) of a vcpu in kernel? Is there a
variant in struct kvm_vcpu or something else indicate this?

Besides, if vcpu1 is running on pcpu1, and a kernel thread running on
pcpu0. Can the kernel thread send a message to force vcpu1 trap to
VMM? How can I do this?

Thanks very much,
Arthur
