similar to: DomU Guests not shutting down nicely when Dom0 Hypervisor shuts down

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

Yes I usually work headless, but I have been setting it up from new, so need to see what is going on. Regards Francis From: "Scot P.

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

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

(1) This made no difference. It still hangs around the same place. (2) It wasn't enabled in the kernel so i enabled it. I then rebooted but unfortunately it made no difference. If you want access to a hypervisor to have a play around, let me know. The only information i really have is that if i installed CentOS 7.3 on this hypervisor it works fine.

Hi Francis. Personally I would gracefully shutdown all the VM?s first, before attempting to shutdown the xen hypervisor. Are you getting any fsck errors when restarting those VM?s?

HI, We've started to see several issues with the Xen releases. Going back to basics I've used this guide https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Once the install process is complete the grub.conf looks like this: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /boot/xen.gz

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

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. No idea what it's doing - but I don't even see the scrubbing free memory output...
