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

Francis, I just rebooted my Precision 470 and watched...nothing :( I see the boot menu, and then everything goes blank - as in just a blinking cursor until I get the login prompt.

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

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.

When I was running Fedora 23 and using Xen (as the host OS), I saw something similar on my Dell Precision 470. I don't recall seeing it now with CentOS 7, but I tend to boot that machine headless more than not...

I am having trouble getting PCI Passthrough to work from Dom0 running CentOS 7 to DomU runnning Debian 8 I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64 on a Dell Poweredge T430. I think I have set it all up correctly, but I see no message when putting a USB device into any of the USB slots on the DomU There are three other DomUs running, but I have no need of PCI Passthrough set up

Package: xen-hypervisor-3.0-unstable-1-i386 Version: 3.0-unstable+hg11561-1 Severity: important I've installed xen-linux-system-2.6.17-2-xen-k7 (version 2.6.17-9) on a server, and planned to run 3 Xen domUs on it. Creating the domUs was no problem, and running two of them works well. Starting the third one however will crash the dom0 and forces it to reboot. The machine is a Athlon64 3800+
