I've been trying to use memdisk with grub2 to boot some iso images -( I've done this without any problem with pxe ) There is a memdisk.mod in /boot/grub/ and I've seen some material talking about this, but no example of a menu. After trying countless permutations - Right now I have : menuentry "Memtest-Plus 4.2" { echo `hello` insmod lvm

Dear Syslinux folks, For a firmware update I am following the Gentoo Wiki [1] to create a floppy image of 20 MB, so that the vendor update utility fits. Unfortunately, FreeDOS does not load, and it seems to hang loading the FreeDOS kernel. The original FreeDOS image boots. Do you know if that issue is memdisk related? It?s started from GRUB with the commands below. linux16 /boot/memdisk

Hello, I'm trying to boot a dos floppy stored on a disk image which is initially loaded over pxe using memdisk. I've created the disk image as follows: dd if=/dev/zero of=$IMGLOCATION/$IMGNAME bs=$(( 1024 * 1024 )) count=20 LOOPDEV=$(losetup --show -f $IMGLOCATION/$IMGNAME) MAJOR_MINOR=$(ls -l $LOOPDEV|awk '{print $5$6}'|sed 's/,/:/') DMSIZE=$(( $(ls -l

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

On Debian family of OSes Grub2 tools are prefixed with 'grub-', not with 'grub2-'. We have to detect the correct name of the tool to use it.

I had CentOS 6 installed on an MBR hard disk. I converted the disk to GPT (with UEFI) and installed CentOS 7 on a new partition. CentOS 7 itself seems to work properly. Grub from CentOS 7 automatically created an entry for CentOS 6, but I get an error if I try to boot CentOS 6. The menu entry is: menuentry 'CentOS release 6.10 (Final) (on /dev/sda7)' --class gnu-linux --class gnu

From: Pavel Butsykin <pbutsykin@virtuozzo.com> This patch improves the search of grub config on EFI partition. This means that the config will be found not only for rhel but also for many other distributions. Tests were performed on the following distributions: centos, fedora, ubuntu, suse. In all cases, the config path was /boot/efi/EFI/*distname*/grub.cfg The main purpose of the patch

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and

Create an object hierarchy to represent different bootloaders for Linux guests, moving the separate handling of grub1 and grub2 in different classes: this isolates the code for each type of bootloader together, instead of scattering it all around. This is mostly code refactoring, with no actual behaviour change. --- po/POTFILES-ml | 1 + v2v/Makefile.am | 2 + v2v/bootloaders.ml

Augeas 1.7.0 was released a couple of days ago. By encouraging everyone to upgrade to this we can drop several calls to aug_transform and also our custom copies of two lenses, and a lot of related code. Rich.

Hello CentOS users, in the recent time I keep getting the logwatch warnings from my 2 dedicated servers running CentOS 7.4.1708. I guess because of the numerous kernel updates (because of Spectre+Meltdown) in the near past? Could someone please suggest me, which files in my /boot partition would be safe to delete? I would like to avoid the situation of having to boot the rescue partiton etc.

Hi.

Expose the aug_transform API through the library, so it's possible to add/remove Augeas transformations to handle files in custom places using existing lenses. --- daemon/augeas.c | 21 +++++++++++++++++++++ generator/actions.ml | 12 ++++++++++++ gobject/Makefile.inc | 2 ++ src/MAX_PROC_NR | 2 +- 4 files changed, 36 insertions(+), 1 deletion(-) diff --git a/daemon/augeas.c
