We here at AMD run daily tests with various combinations of Linux and Windows guests - and it works (for most of the time, sometimes we break our own code, and sometimes it''s broken elsewhere in the development tree, that''s what you get from running "unstable"). But I didn''t reply to your initial question because: 1. It''s not clear what you mean by "proven". 2. I think I''d be considered "biased"... ;-) -- Mats> > thanx for hints / GW > > > Gerhard Wendebourg schrieb: > > Hello all, > > > > is the use of OS''es like Windows on Xen with AMD-cpu > already proven, are > > there experiences or still matter of theory? > > If it is: may I use for running Windows on Xen any available > > AM2-mainboard, or are there only specific chipsets > supporting a system > > like that? > > > > thanx for replying / GW > > > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

My disk specification is exactly as in the first.
disk
[''phy:/dev/domU/dom1root,hda1,w'',''phy:/dev/domU/dom1swap,hda2,w'',''phy:/dev/hdc,hdc,r'']
However the CDROM is not visible domU
/dev/hdc is definitely in Dom0, but is not in DomU.
I am using 3.0.3. Is there another step that must take place. As far as
DomU is concerned it should be a block device name /dev/hdc.

or

cdrom = ''/dev/hdc''
You should only need this, not the latter two.

AND 2) There is software to support the hardware in Xen. OR 3) There is special drivers that understand virtualization and can differentiate the Machine physical addresses needed by the PCI device and the Guest physical addresses that the guest BELIEVES is the physical address. -- Mats _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Xen/Windows on AMD; use of PCI / USB
> since I found, that AMD is suitable to work with Windows on Xen, the > additional question for the use of physical PCI / USB Devices by the > Windows-guest.Passing PCI devices through to Windows guests won''t work, and probably won''t work for the forseeable future (really, you''d want IOMMU hardware for this to work, and "normal" x86 systems don''t have this hardware). You might be able to pass USB devices through from dom0 by configuring the attached devices appropriately... Vanilla Qemu can pass USB devices through to its guests, so maybe the Qemu device models can also do this... USB is fundamentally easier to pass through to guests, which is why its available and PCI passthrough is not. Hope that helps some, sorry for not being more specific.
