Hello all, I hope that it now works and there is no longer problems with my mailsystem. It could be that it already worked but it doesn''t look like because the mail don''t came back from the list. I am trying to setup stubdomains for my running domains on Xen 4.2. I read this wiki articles: http://wiki.xen.org/wiki/StubDom http://wiki.xen.org/wiki/Device_Model_Stub_Domains I am able to activate a stubdomain for a normal domain but this domain is so basic in it''s resources (e.g. 32MB RAM) that the normal gues...

Hello all, I have question about the configuration of stubdomains. I read the Wiki articles about that theme and I am able to tell a domain to use stubdomains but this stubdomains are so basically (e.g. 32MB RAM) that the guest isn''t usable. How can I tell the domain/stubdomain which configuration should be used for the stubdomain? And should I use...

Otherwise after a localhost migrate of an HVM domain with a stubdomain we end up with domains called "FOO" and "FOO--incoming-dm".

Dear all, Firstly I apologise for what may be a fairly simple question, but after spending a few days on this I really need the help of an expert. I''m developing a stubdomain based on Mini-OS and I''m trying to convert the virtual address of a shared memory page to a machine frame number. I would have thought this requires an #include <xen/page.h> library, but it is not

Hi, recently on irc channel (##xen) was some "discussion" about xen vs kvm... There was idea that it would be nice if domUs could survive dom0 restart, but this needs, for example, to have xenstored running in separate domain. In 2009 Alex Zeffertt posted some patches (http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00696.html) to add this functionallity, but they

...to a buffer overflow attack. IMPACT ====== A guest which has access to an emulated floppy device can exploit this vulnerability to take over the qemu process elevating its privilege to that of the qemu process. VULNERABLE SYSTEMS ================== All Xen systems running x86 HVM guests without stubdomains are vulnerable to this depending on the specific guest configuration. The default configuration is vulnerable. Guests using either the traditional "qemu-xen" or upstream qemu device models are vulnerable. Guests using a qemu-dm stubdomain to run the device model are only vulnerable to t...

Hi, I''m using a custom block script in my xen setup and when started, it creates a new device node pointing to some network resources. Now I noticed that the script is called twice for the root block, the first time for pygrub most likely, but is only stopped once ... I don''t mind creating two devices node, but then I need to destroy both ... Is this a known issue ? Cheers,

This patch enables PCI passthrough with stub domain. PCI passthrough with stub domain has failed in the past. The primary reason is that hypercalls from qemu in stub domain are rejected. This patch allows qemu in stub domain to call the hypercalls which is needed for PCI passthrough. For security, if target domain of hypercall is different from that of stub domain, it rejects hypercall. To use
