similar to: Xen hypervisor on CentOS 7.4 with modern UEFI server not booting from grub

Why do you need UEFI? It does not add to security "a lot" but was designed to block booting software like a "hypervisor". I used my Dell notebooks to test our hypervisor identification software (HyperCatcher if you are interested) which is bootable image. However, I was unable to boot it until I disabled UEFI. As I understand it, it will block anything from booting excepting

I checked and secure boot is turned off. Jonathan brings it exactly to the point: we have to face UEFI because legacy mode is fading out, if I enable legacy mode I can't even boot anymore through the network (PXE) as these newer network cards can only boot PXE with UEFI. In the mean time I have installed Ubuntu 17.10 with Xen and I was lucky to see that this combination works with UEFI even

UEFI PXE is different than BIOS PXE and needs to download different

I see the announcement from February that it's available, but is it considered to be safe for Production use? The documentation in the SIG still only references CentOS 6. https://wiki.centos.org/Manuals/ReleaseNotes/Xen4-01 https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I ran today update of my CentOS 6.9 running on Dell T105 (AMD OPTERON) and httpd failed to start. Any idea what could cause that? I never had a problem after CentOS 6.x update. Web server runs since March 2017. I do updates usually once in a week. Thank you Mikhail Utin

The matter of EUFI?s Secure Boot vs Legacy Boot has been briefly discussed a couple of days ago. I would ask the List opinion concerning our case. A bit of the history. We?ve been in the research of malicious hypervisor threat since 2013. We finally developed publicly available HyperCatcher freeware. It runs on specially built Ubuntu 14.4. We tried CentOS 6/7 as well. The OS was compiled to

Hello, I posted a question over at xenproject.org but it was recommended that I send out a message here for help. My post there: http://www.xenproject.org/help/questions-and-answers/vanilla-pv-centos-guest-via-kickstart-centos-6-6,-xen-4-4.html The TL;DR is: Everything I've found to kickstart a new vanilla rhel/centos guest points to specifying a kernel & and initrd- for RHEL/Centos 5.

In honor of Xen Doc Day, I've put up some basic HOWTOs for setting up bridging on CentOS 6 and 7. I'm far from an expert, so I'd appreciate any feedback.

Hi, Actually, we study virtualization on CentOS with Xen, our goal is to test if the migration of Xen with SLES 11 to CentsOS. Our first tests are ok except for one problem and I don't find any solutions on the net. I hope, you can help me. The problem is that I can't connect to my vm desktop with Virt-Viewer. I follow the installation guide available for centos?:

Hi, after migrating to libvirt/libxl according to: https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt I've noticed that my Xen PV domains are being launched by qemu-system-i386 running under root privileges. I am wondering why is this? Previously no qemu process was used. If qemu is needed for some reason, are there any guidelines for non-root operation? Thanks -- Karel

Hello, we have a strange problem on a fresh install of CentOS 6.5. On the server we want to use Xen to host paravirtualised guests (the system has no hardware virtualization support). To manage the domain we would like to use libvirt. Xen and libvirt are set up as described here: http://wiki.centos.org/HowTos/Xen/Xen4QuickStart http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt When

Dear all, Maybe I'm the only one - so before filing it as a bug: it appears that the latest set of kernel patches in 3.10.0-693.11.6.el7 makes issue 0013763 "CentOS 7.4 kernel (3.10.0-693*) fails to boot as Xen PV guest" re-surface *also* with the CentOS PLUS kernel. But maybe in a different way ... Thanks to the (great!) quick work on making the plus kernel available (in #14330,

Hi all, I'm trying to install libvirt for xen on a brand new, minimal installation of CentOS 7.5.1804. After installing the OS, I did a 'yum update' and followed the basic how-tos at https://wiki.centos.org/HowTos/Xen/Xen4QuickStart and https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt From previous experience, I know that the above steps worked fine.
