You need to build your kernel with:

There's two more under "Misc Devices"...
VMware Balloon Driver
VMware VMCI Driver

Edit: I give up trying to format properly here. Crappy php software.

Perhaps this will make it easier. There's a 4.4.50 kernel config attached for VMware, just rename out the .txt extension. If you're running a newer kernel just copy this in and make silentoldconfig before building.

Luridis thank you so much
please explain steps I can't understand

The attached file is a kernel configuration for running on vmware.

Untar a fresh kernel source and run: make mrproper.

Copy in that file and rename it to .config

If the kernel you unpacked is newer than 4.4.x then run: make silentoldconfig

It may ask a dozen questions or so, answer them.

Finally, run: make && make modules_install


If you're having a hard time understanding all that from a technical perspective, then you lack the proficiency you'll need to build and maintain a LFS system. If that's the case, use something like Arch Linux for a while.

what is the problem it is
kernel panic not syncing vfs unable to mount root fs on unknown-block 8,3

You need to post some info!!!

post grub.cfg
and fstab

no one can guess, you need to supply something

spiky0011
my /etc/ there is no grub.cfg file only grub.d is
present
here is my /etc/fstab file
# Begin /etc/fstab

# file system mount-point type options dump fsck
# order

/dev/sda3 / ext4 defaults 1 1
proc /proc proc nosuid,noexec,nodev 0 0
sysfs /sys sysfs nosuid,noexec,nodev 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /run tmpfs defaults 0 0
devtmpfs /dev devtmpfs mode=0755,nosuid 0 0

# End /etc/fstab

To understand the -concept- of why (what's wrong), the kernel can't mount the [grub] root=...
because either it doesn't have the disk driver, or that root= specifies wrong partition!
/boot/grub/grub.cfg

what to do
jjanel

Create a grub.cfg if you dont have 1, thats the problem

spiky0011
can you help me for this how to generate grub.cfg

Heres whats on LFS
http://linuxfromscratch.org/lfs/view...er08/grub.html

and google will help try it.

I think a little input from your self to learn will help you

Can you mount sda3 on somewhere like /mnt?
I think your /mnt/boot/grub/grub.cfg IS there!
(Are you familiar with the concept of mounting a filesystem?)

But, can you 'prove' 2 things: (I'm not sure exactly how to you would do this in your particular system)
1) sda3 -is- a 'valid' root meaning / filesystem (for LFS!)
2) the SATA disk driver is in the kernel config
(I'm 'worried' because I don't understand what's going on in posts #2-5!)

which one run
1)

cat > /boot/grub/grub.cfg << "EOF"
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5

insmod ext2
set root=(hd0,2)

menuentry "GNU/Linux, Linux 4.9.9-lfs-8.0-rc1-systemd" {
linux /boot/vmlinuz-4.9.9-lfs-8.0-rc1-systemd root=/dev/sda2 ro
}
EOF

2)
cat > /boot/grub/grub.cfg << "EOF"
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5

insmod ext2
set root=(hd0,2)

menuentry "GNU/Linux, Linux 4.10.1-lfs-SVN-20170303" {
linux /boot/vmlinuz-4.10.1-lfs-SVN-20170303 root=/dev/sda2 ro
}
EOF
