Re: [Xen-devel] Thread in hypervisor

["George Dunlap" <gdunlap@xxxxxxxxxxxxx>]

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?
