similar to: Xen UEFI how to install and configure

I''m using xen 4.3 with gentoo as dom0. the kernel and ramdisk file is taken from http://ftp.jaist.ac.jp/pub/Linux/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/ the pv domU config file (according to the ubuntu xen documentation https://help.ubuntu.com/community/Xen) precise.cfg name = "precise" kernel = "/xen/kernels/precise/vmlinuz"

Hi, I had the same sort of issue. My workstation with a Asrock motherboard suddenly decided to reset UEFI to defaults which caused my Fedora installation not to boot. I could boot with a Live USB stick and use efibootmgr to set the UEFI boot for Fedora but next time I powered on my machine the same issue happened (I remove AC power from my workstation when it is not in use). Turned out to be

I?ll explain what?s happening first, and list the steps after that. First: pep is short for the Xen target x86_64-pep. It?s a target you can enable when configuring Xen to create an EFI binary. What is happening with Xen on UEFI via Grub is that it doesn?t give the kernel any info on the ACPI root pointer. Basically, this means that Linux won?t be able to do ACPI, and therefore a ton of hardware

Not all UEFI guests can survive conversion, because of lost bootloader information in UEFI NVRAM. But some guest can cope with this because they have a fallback bootloader and use UEFI Removable Media Boot Behavior. (see https://uefi.org/sites/default/files/resources/UEFI_Spec_2_8_A_Feb14.pdf 3.5.1.1 Removable Media Boot Behavior) to load. If UEFI firmware can't find a bootloader in its

As an addition to anyone having issues with booting but only getting 1 CPU and a ton of devices that misbehave, check to see if you have an RSDP in Xen and Linux. You should have both (I use xl and not xm): sudo xl dmesg | grep RSDP (XEN) ACPI: RSDP DDA4A000, 0024 (r2 SUPERM) and sudo dmesg | grep RSDP [ 0.000000] ACPI: RSDP 00000000000f0010 000024 (v02 SUPERM) I?m running this on a

v2: Rich, I hope I've done all modifications according to your comments, namely: * moved the code from linux_bootloaders to convert_linux * made minor code modifications --- Not all UEFI guests can survive conversion, because of lost bootloader information in UEFI NVRAM. But some guest can cope with this because they have a fallback bootloader and use UEFI Removable Media Boot

Hi list, What is the best method to migrate Hyper-V 2012 VM to oVirt/RHEV ? I made a v2v livecd, but it never load consoles and never launch p2v service (works well with BIOS VM or hardware, but G2 HyperV VM needs EFI to boot). I must add some packages on my system to build an EL7 (kmod-hfsplus from elrepo) and some other to boot on EFI : #boot EFI grub2 grub2-efi grub2-efi-modules

Hello, While testing Virt-SIG Xen 4.12 rpms on CentOS 7, I noticed the default Xen hypervisor console= option parameters are broken, and result in an error from Xen, and no output on the physical vga console: >From xen dmesg: (XEN) Bad console= option 'tty' Xen 4.12.0-1.el7 (XEN) Xen version 4.12.0-1.el7 (mockbuild at centos.org) (gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)) debug=n

No, this logic is flawed. Running grub2-install is obsolete on UEFI, it only applies for users who know exactly what

hi guys I have a box on which UEFI boot has gone haywire and instead of boot it power the box down, that is before even going to grub2. (displays some error message) I if change to BIOS boot then I can start Centos' rescue - my question is: how can I rescue, re-build grub so it would boot from tradition BIOS? many thanks, L.

Hello All, updating from Centos7.3 to Centos7.4 rendered one of our laptops unbootable. EM: Failed to open \EFI\BOOT\grubx64.efi - Not Found Failed to load image \EFI\BOOT\grubx64.efi: Not Found start_image() returned Not Found How could this occur because of an update and how to fix this? What I tried is booting from centos usb, chroot to /mnt/sysimage and gave command: efibootmgr
