Zitat von Ian Campbell <Ian.Campbell@xxxxxxxxxx>:

That page looks very obsolete to me. I have no idea if the steps it
describes are needed for xm/xend but they are certainly not correct for
xl. http://wiki.xen.org/wiki/Device_Model_Stub_Domains is correct for xl
AFAICT.

Ian,
is the http://wiki.xen.org/wiki/StubDom page up-to-date? It would be
good to clear this up (and move the old stuff - if it doesn not work any
more) into a Xen 3.x and Xen 4.x section. I can do this, I just don't
know from this thread whether the page is still valid.

Hello,

yes so for a Windows guest this works now, can PV guests use ioemu Stub Domains also? And are there some documents about xenstore stubdomains? For driver domains there is a document in the wiki, will try to get it working but for xenstore stubdomains I can't find anything.

Best Regards
