Dear Jean-Marc, Thank you for replying. I Installed CentOS 7 and centos-virt from the normal repos (CentOS-Xen) in December 2015 and have not had to build anything. I am running CentOS 7, not sure if it has automatically updated itself to 7.3, so I would expect the updates to come from the repo, and not need building from source.

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

PJ My server is critical to me, but not the public, fortunately. I can take it down as I suggested, but am a bit reluctant to do so until I have heard more opinions. Presumably your system update failed using your script, so it will probably fail for me if I copy it. I will keep a copy anyway. ----- Original Message ----- > From: "PJ Welsh" <pjwelsh at gmail.com> > To:

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

Further to my last post, I have removed the xen-pciback module from the Dom0 kernel, and reloaded it as modprobe xen-pciback passthrough=1 I now have the PCI device on the DomU matching the Dom0 Device usb usb1: SerialNumber: 0000:00:1a.0 instead of 0000:00:00.0 However I now have this error ehci_hcd 0000:00:1a.0: Unlink after no-IRQ? Controller is probably using the wrong IRQ. does

The CentOS 7.3 release updated to libvirt 2.0, which is now taking precedence over the previous virt sig libvirt packages (which were 1.3). I've pulled in the changes from Fedora 25, which uses libvirt 2.2.0. I've built and tested them for CentOS 7 and they work for me. (I'm having some infrastructure issue testing C6.) Please test them if you have an opportunity. I'll leave

Jiri Denemark has already proposed to help rebuild libvirt for CentOS-Xen but I don't know if he got all that is need to do so ? Maybe I could help also, but I would have to learn the Centos build system first.

As libvirt from Xen is 1.3.0 and libvirt from CentOS 7.3 is now 2.0.0, libvirt from Xen has to be rebuild to upgrade the new libvirt 2.0.0 See my previous post : https://lists.centos.org/pipermail/centos-virt/2016-November/005255.html I've done it for my own repo : https://copr.fedorainfracloud.org/coprs/jmliger/virt7-upstream/ Regards, Jean-Marc Le 30/12/2016 ? 17:56, Francis The

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

Thank you. I will try the centos-virt-xen-testing in development hopefully soon.
