The kernel is loaded from the guests directory structure that is exported from the host. - -The problem is that QEMU does not reload the kernel image file from disk during a guest reboot. This means it is not possible to update the kernel from inside the guest and do a simple reboot to load it. A full power cycle of the guest is required to load the updated kernel image. -Steps to reproduce: -1. Migrate a Linux guest to virtiofs as root fs. -2. Enable QEMU direct kernel boot and point to guest's kernel in the exported root filesystem. -3. Boot. -4. Update the kernel inside the guest. Overwrite the existing kernel image -5. Issue `reboot` inside the guest. -6. When the guest reboots, the old kernel is still booted, even though the image file was overwritten. -7. Issue `poweroff` inside the guest. -8. Issue `virsh start <guest-vm>` -9. Now the new kernel image is booted. -Additional information: -XML: -``` -<type arch='x86_64' machine='pc-q35-7.0'>hvm</type> - <kernel>/media/vm/libvirt/images/alpine-q/root/boot/vmlinuz-virt</kernel> - <initrd>/media/vm/libvirt/images/alpine-q/root/boot/initramfs-virt</initrd> - <cmdline>rootfstype=virtiofs root=root rw</cmdline> - <boot dev='hd'/> - <bootmenu enable='no'/> - </os> - -... - - <filesystem type='mount' accessmode='passthrough'> - <driver type='virtiofs'/> - <binary path='/usr/libexec/virtiofsd' xattr='on'> - <cache mode='always'/> - <lock posix='on' flock='on'/> - </binary> - <source dir='/media/vm/libvirt/images/alpine-q/root'/> - <target dir='root'/> - <address type='pci' domain='0x0000' bus='0x09' slot='0x00' function='0x0'/> - </filesystem> -``` |
