Hi

I P2V my Linux to VMware, but the Linux (VMs) cannot bootup, errror message "Kernel panic: no init found. Try passing init= option to kernel".

Any buddy know how to resolve that.

Thanks!

What method did you use to perform the P2V ?

I using VMware converter bootable CD to perform P2V, version is 4.0

Thanks

Usually this means that the system doesn't know which disk-drive is supposed to be the root volume. This is often specified as a kernel-parameter. Generally the configuration of the boot-loader (e.g. grub) specifies that value.

It can be handy to boot up a live-CD in your virtual-machine because they are especially designed to figure out how to get themselves started. You can then more-easily "have a look around" to see what the kernel is actually seeing when it tries to start.

When I boot to "linux secure" mode then enter command "fdisk -l", display below info (just capture some info).

Device Boot Start End Blocks Id System
/dev/sda1 * 1 7 53024 83 Linux
Partition 1 does not end on cylinder boundary
/dev/sda2 7 2922 23411040 83 Linux

Why "Start" and "End" have conflict?

How to fix that.

Thanks!

They're not conflicting .. that's just a warning. Try booting on a live cd of the same distro and version as you P2V'ed .. then chroot into the local disk and recreate initrd. Actually I don't think chroot is required...

Hi kbp

Thanks for your reply.

How to chroot, can you provide detail procedure, because I'm is Linux newbie.

Thanks!

Like I said, I don't think chroot is required .. take a look at the man page for mkinitrd. All you want to do is create a new one that includes the relevant controller drivers, by booting on the live cd the correct controller drivers will probably be loaded and mkinitrd will automatically include them.
