Yethal, Thank you for your efforts.
I did not discover anything down this path. Further, when I booted today, the keyboard and mouse came up immediately. I also had my access point running and it was logged into during the boot. Although previously, with the AP available at boot, sometimes it came up without the keyboard and mouse. I am stating this as I had problems with a Debian correctly booting with out a wireless connection. More directly to your suggestions, here are the transaction I performed: OK, I don't know how to paste from dom0 to this fedora disposable vm. I did a sudo xl dmesg | grep VT for VT-d It displays supported pages sizes for iommu 0 It displays supported pages sizes for iommu 1 Snoop control not enabled. dom0 dma passthrough not enabled queued invalidation enabled interrupt remapping enabled shared ept tables enabled "Its risky to assign' address 'with shared rmrr at" address for Dom1. xl dmesg for strict displayed (XEN) - Unrestricted Guest xl dmesg for pci did not produce anything xl dmesg for usb did not produce anything I checked all the above just after booting into the system. I then started up USBvm from the application menu while having xl top running. As before, it showed paused for about a minute and then disappeared. I ran the above queries again and obtained the same results. Any suggestions? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
