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

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

How do I assist with getting this in for Jessie? I have this working in a fairly easy setup, it basically only requires the pep target to be on for debian?s Xen package, and a tiny bit of infrastructure to get xen.efi, vmlinuz, an initrd and a xen.cfg on to the ESP partition and letting the efibootmgr know about it. I already have a oneliner to do this manually, but it isn?t that hard to

I have installed dom0 Wheezy 64 bit on Dell PowerEdge T310 with kernel from package and xen-unstable. System is in Uefi mode and booted with grub-efi-amd64. Booting without xen efibootmgr works, while with xen not, efivars kernel module is loaded but show this message: efibootmgr Fatal: Couldn''t open either sysfs or procfs directories for accessing EFI variables. Try ''modprobe

OK, one other tidbit: The EFI BIOS has a UUID in its boot options. I expect that this identifies the old system disk, but I don't know where that UUID comes from. It is NOT the VFAT UUID for the EFI partition and is not any of the UUIDs for any of the Linux file systems or RAID arrays, or really anything else I can find under Linux. I'm guessing it is something the EFI BIOS has

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

Morning all, I have a HP Envy dual boot system (Win8 for serious stuff, i.e. Train Sim and Flight Sim) and Centos 7 for everything else. In the past I've had the occasional problem where an update on the windows side has updated the UEFI boot sequence but using efibootmgr has always fixed it. On Friday I discovered that my HDD was failing so I tried using Clonezilla to move it on to a new

Hi, all I''m new to xen recently. I''ve managed to install the xen on a BIOS machine, and boot into xen dom0, setup a domU guest, all goes well. So I decided to turn my desktop into a xen server. It''s running on UEFI. The machine runs on Gentoo Linux with kernel 3.11.0. I''m using xen-4.2.2 , it''s built with efi USE FLAG , and install the xen-4.2.2.efi
