Hi,
I have gaming windows hvm working with xen 4.3. after updating to xen 4.8, I cannot PCI-passthrough my USB controller anymore. The pci passthrough works fine for graphic card and audio. here is the error I get with rdm_policy=strict : [VT-D] It's disallowed to assign 0000:00:1d.0 with shared RMRR at bdbe3000 for Dom2. (XEN) XEN_DOMCTL_assign_device: assign 0000:00:1d.0 to dom2 failed (-1) with rdm_policy=relaxed, the VM start, but I get a blue screen ... I've tried the 3 USB controller of my motherboard, and all gave the same error. how to check why RMRR is shared, and with which device it is shared ? Thanks in advance, -- Jocelyn _______________________________________________ Xen-users mailing list [hidden email] https://lists.xen.org/xen-users ![]() ![]() ![]() |
I reply to myself because I was able to
solve it thanks to this post :
https://groups.google.com/forum/#!topic/qubes-users/gS1XTal8XYs I have to pass all the USB controller sharing the same RMRR to the same domU to make it work. Adding this to the domU configuration : '00:14.0,rdm_policy=relaxed', '00:1a.0,rdm_policy=relaxed', '00:1d.0,rdm_policy=relaxed', and I have now this in the logs, but the VM works fine : (XEN) [VT-D] It's risky to assign 0000:00:14.0 with shared RMRR at bdbe3000 for Dom4. (XEN) [VT-D] It's risky to assign 0000:00:1a.0 with shared RMRR at bdbe3000 for Dom4. (XEN) [VT-D] It's risky to assign 0000:00:1d.0 with shared RMRR at bdbe3000 for Dom4. -- Jocelyn On 12/05/2017 00:49, jocelyn falempe wrote: Hi,
