It looks like most LVM stuff (device mapper
) is in. Can you share your boot configuration, i.e. Grub config file, kernel command-line and if you can where the kernel panicks?
Partial Grub config:
menuentry 'ACRN multiboot2 ' --id ACRN_deb_multiboot2 {

insmod gzio
insmod part_gpt

Kernel panics for detect init and root partition.
Hi @ionutnechita , I do not have (yet) any hands-on experience with booting a system off LVM. But my understanding is that it requires some initramfs because some user-space utilities are needed to mount those partitions. Enabling the right kernel options may not be sufficient.
If true, I don't know how to create and use such initramfs off the top of my head, especially with this multiboot2 protocol. Perhaps @ZideChen0 or @jsun26intel know more about this?
To load ramdisk, you may try:
1) add the ramdisk_mod_tag to vm_configurations.c. You may use acrn config tool or modify ACRN source code directly. For example:
@@ -30,6 +30,7 @@ struct acrn_vm_config vm_configs[CONFIG_MAX_VM_NUM] = {
.name = "ACRN Service OS",
.kernel_type = KERNEL_BZIMAGE,
.kernel_mod_tag = "Linux_bzImage",
+ .ramdisk_mod_tag = "xxxxx",
.bootargs = SOS_VM_BOOTARGS,
},
2) add one line to the grub config file: module2 /boot/your_initrd xxxxx
Before doing this, probably you may play on native Linux to load kernel from non-LVM and mount root from LVM first to make sure every component is properly configured. BTW, SOS kernel is supposed to be boot on native without ACRN.
Thanks @ZideChen0 !
@ionutnechita , is this something you can try?
Ok, understood this two steps.
Thanks @gvancuts and @ZideChen0.
Will be try in feature this configuration.
Hi ACRN team,
I try to boot with LVM disk partition, but SOS enter in kernel panic. LVM is supported in Kernel and SOS kernel config file?
Thanks.
