The Linux kernel is that the Linux kernel keeps kernel process stacks, so you can have a "kernel thread". Xen does not keep in-hypervisor stacks around -- once Xen returns to domain-space, all context is completely gone. So there can be no 'hypervisor threads'. (It's a weird concept to get used to at first.) So your options are basically, to create a specialized domain to do whatever "thread" activity you want done, or to use a timer function to do the same thing. What kind of a task are you talking about? -George On 4/17/07, Sangmin Lee <sal008@xxxxxxxxxxx> wrote: Hi all, I would like to run some tasks in context of hypervisor. I saw some suggested to use timer but timer function seems to run in context of a domain which is currently running. What I want is something like kernel thread in hypervisor,( hypervisor thread :-) ). Does anyone have any idea on this?
