[Xen-devel] Possible BUG: starting more than 1 domain with same pci= passthrough device
Xen 3.4-rc1 Dom0: 2.6.18.8-xen0 (pciback.hide="03:00.0") DomU: Linux pv 2.6.26-1 (Debian) ( pci=[''03:00.0''] ) DomU: Windows XP SP3 HVM ( pci=[''03:00.0''] ) Starting Linux PV with passthrough graphics OK, then start Windows HVM with passthrough also (happened by accident) and xentools proceeds to start without warning or error. The passthrough to Windows HVM is not working anyway. Switching off the Windows HVM then caused a complete lock up on Dom0, had to hit the reset switch! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Yes, this is a known issue (please see the attached mail). I have no time to fix it for now. :-( Hope somebody can kindly help.
