I am running Xen 4.6 on CentOS 7 in a Dell Poweredge T430 I need PCI Passthrough to get USB working. I am following the Xenproject Wiki I have enabled the Virtulasation in the BIOS. I have xen_pciback as a module I have issued the command: xl pci-assignable-add 00:1a0.0 and it shows up fine when I issue this xl pci-assignable-list I have pci=['00:1a.0'] on the DomU config file I

I am using Xen 4.6.0-8.el7 on CentOS 7 with 3 Linux DomUs. I did have Xen 4.? on CentOS 6.5 on my previous system. I installed using yum install centos-release-xen. On shutting down the Hypervisor it used to wait for the DomUs to shut down gracefully (one can take a minute or more), then on starting up again it would restart the DomUs, all nice and controlled. For some reason the DomUs (CentOS

Dear All I am using Centos 7 with Xen 4.6 on a Dell Poweredge T430 When the machine boots, after the 'Scrubbing Free RAM' message, I get a screen filled with little white squares until the login prompt, so I cannot see what is happening as the machine boots. Also there is nothing on the screen when I reboot. My /etc/default/grub is GRUB_DISTRIBUTOR="$(sed 's, release

Further to my messages back in May I have at last got round to trying to get my DomU to recognise USB devices. I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64. I have to manually make the port available before creating the DomU by issuing the command: xl pci-assignable-add 00:1a.0 otherwise nothing shows in: xl pci-assignable-list I have added this to my .cfg file as per the
