[Xen-users] xc_domain_unpause in xc_linux_save

I've been digging through the Xen Unstable source, in an effort to find
out why paused domains don't save.
Whenever I try to save a paused domain, a small amount of data is
written to disk (domain config stuff), and then the save hangs forever
(more than 1 hour).

I came across a call to "xc_domain_unpause" in "suspend_and_state"
(which is called by xc_linux_save in xc_linux_save.c), and I don't
understand why the domain is being unpaused before being saved.

Does it have to do with the context of the VCPUs?
Is there some voodoo that makes paused domains impossible to save?

Can anyone enlighten me?

Thanks,
Wesley
