2015年4月19日 · “vmlinuz” as a format name does mean “gzipped vmlinux file which got stripped of all its symbols”. However, as a file name, vmlinuz is often used for any kernel image which is in a compressed format that a bootloader supports, such as the zimage format or …

The bzImage (big zImage) format was developed to overcome this limitation by splitting the kernel over non-contiguous memory regions. The bzImage was compressed using gzip until Linux 2.6.30. The bzImage file is in a specific format.

Hm, I actually had the same problem first, the cause was that the script failed to create a needed temporary file /tmp/vmlinux-XXX (in my case, I needed to change that to /tmp/vmlinux-XXXXXX to get it working, the needed number of X'es should be mentioned in the manual page for mktemp).

2006年5月20日 · bzImage just means Big zImage. zImage can only be a maximum size 512k. Unless the kernel will be that size or smaller after compiling then you need to make it as bzImage. Earlier kernels where quite able to fit in the 512k range but over time many new features have been added and the zImage limits were reach and something new had to be done.

From qemu's help: Linux/Multiboot boot specific: -kernel bzImage use 'bzImage' as kernel image -append cmdline use 'cmdline' as kernel command line -initrd file use 'file' as initial ram disk -dtb file use 'file' as device tree image

2009年8月13日 · Then I downloaded and compiled the latest Linux kernel version 2.6.30.3 in order to replace my older Linux-2.6.26-2-686. happily I managed to build the bzImage. For the next README file step, I need to find my older bzImage, and to replace it with the new one, for the grub boot loader.

2012年3月1日 · The bzImage filename and make target was originally x86-specific (big zImage). Many of the bootloaders on architectures that are not equal to baremetal-x86 (SPARC, PPC, IA64, etc. and also Xen on *) directly take vmlinux (or one of its compressed forms, for example vmlinux.gz, aka zImage).

2004年6月23日 · What you need to do is move the bzImage to the location you want it (if you dont have a separate boot-partition you want to use, you can even leave it where it is. Not advisable though.) and configure your boot loader to use this file …

2017年10月4日 · What is the difference between them? Image: the generic Linux kernel binary image file.. zImage: a compressed version of the Linux kernel image that is self-extracting.

2021年1月29日 · I have a similar problem as well, even I followed the answer from @Martins3 . I intended to swap the kernel from an existed .qcow2 file but I still cannot log in my qemu.
