Using memdisk with grub2 and a compressed iso
Hello,
I'm having a problem booting a compressed ISO image using memdisk via grub2 (version 2.02). The entry in my grub.cfg looks like:
menuentry 'boot ISO image' {
linux16 /memdisk iso
initrd16 /my-image.iso.gz
}
When selected, this starts to boot and then fails with:
Ramdisk at 0x37979000, length 0x0033b298
gzip image: decompressed addr 0x7f7f7000, len 0x00008f58: failed
Decompression error: output buffer overrun
FWIW, my-image.iso.gz is 3388055 bytes long compressed, and 9...

UEFI memdisk freeze
Hi all,
My computer is booted with UEFI and Grub2. I tried to load VHD files
with memdisk and boot from there. memdisk is extracted from
'bios/memdisk' in syslinux 6.03 zip file.
In Grub2, I executed:
linux16 /memdisk harddisk
initrd16 /Win10.vhd
Then the system frozen at 'initrd16' line.
The VHD file is 8192MB, fixed image. I also tried to boot a small
floppy disk (FreeDOS), and no error reported from Grub2 or memdisk
side.
Is there anything wrong with my steps? How to properly load an fixed
VHD image to ram disk and b...

Memdisk and big floppy images
...0 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 floppy
initrd16 /boot/freedos.img
boot
Kind regards,
Paul

This works perfectly on a virtualbox installation, I get a dos

On a live system it works till till the boot of the dos floppy. The

UEFI and PXE
.... CentOS6 UEFI PXE is working, but the machine won't boot.
It is best to use the CentOS7 BOOTX64.EFI loader. The "kernel too old" message is due to the fact that the PXE config file uses linuxefi and initrdefi directives. They need to be changed to linux/initrd, respectively. linux16/initrd16 may also work. The arguments to those directives need to adhere to CentOS6 legacy grub syntax (ks instead of inst.ks etc.).
This will cause error messages on the client that both linux and initrd are unknown commands. The fix is to add the linux module to the PXE config file,
insmod linux
The cl...

Weird results from g.sh()
Hi,
I'm using libguestfs 1.42,
When I run the following python3 commands on a rhel7.8:

print(g.sh('ls /sys'))
I get:

It seems that g.ls('/sys') is chrooted correctly.
But g.sh('ls /sys') isn't.

Booting CentOS 6 with Grub from CentOS 7
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
