We need a way to do two things to /usr/bin/grub-bootxen.sh in Xen4CentOS. 1. Automate running it if xen (the package) and the xen kernel are installed. But only if the user WANTS to run it. 2. Allow users to automatically modify the variables passed into the xen.gz line (that is, more or less memory, add console settings, etc.) If you look at the current script,

As of the latest updates to anaconda and grub2 for Fedora 18, it is now possible to install with /boot as a btrfs subvolume. The way that grub2 is handling this is the "reach down" to the files it needs as if the subvolume was a directory. Is this OK? At this point I am not worried about snapshots or any other complexities. If the subvolume name is known. should grub2 be able to

Hi all! I've just installed C7 on my netbook that already contained Win7 (and also Fedora 19, which the C7 is intended to replace). The Fedora installer had found the windows installation and it appeared in the grub menu, and was bootable and worked fine. The C7 installer did not put the windows installation into the grub menu. with some googling I found a page at

Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14

Hi. Im trying to set intel_iommu=on on kernel parameters at grub but for some reason it doesnt work. I edit /etc/default/grub file and i add the parameter. then i run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg and then i reboot. when i run virt-host-validate i get QEMU: Checking if IOMMU is enabled by kernel: WARN (IOMMU appears to be disabled in kernel. Add intel_iommu=on to kernel

Hi, I'm using libguestfs 1.42, When I run the following python3 commands on a rhel7.8: print(g.ls('/sys')) print(g.sh('ls /sys')) I get: [] block bus class dev devices firmware fs hypervisor kernel module power It seems that g.ls('/sys') is chrooted correctly. But g.sh('ls /sys') isn't. I came across this behavior when I used

I think i might have solve it. For some reason grub2-mkconfig doesnt work. (Have no idea why) I manage to solve it with grubby. sudo grubby --args="intel_iommu=on" --update-kernel=ALL For some reason it works. I dont know if it works if my kernel gets upgraded.

Hi list, I reinstalled on my workstation CentOS 8.1. I explain: I'm a KDE user but packages shipped from EPEL currently are buggy so I prefer a stable and functioning system to work with. So I tried to remove KDE workgroup and installed group "Workstation" but the system bricked so I reinstalled with GNOME. I've an nvidia gtx 1050ti GPU so I installed kmod-driver from

I have RHEL 7 Beta installed in dual boot with CentOS 6.x. Since RHEL 7 installed GRUB2, I had problem that RHEL 7 is default boot. My personal solution was to go to /etc/grub.d and run command: mv 10_linux 31_linux grub2-mkconfig -o /boot/grub2/grub.cfg Explanation: - /etc/grub.d is where grub2 writes down config files used to create boot menu. - OS-prober creates 30_os-prober file in
