Hi,

I "tried" install gento on my Vmware but after reboot I got bad error...

kernel panic :

not syncing: VFS unable to mount root fs on unknown - block (8,3)
Cannot open root device "803" or unknown-block(8,3)
Please append a correct "root=" boot option: here and the available partition

I used Gento miniman instalation CD. Kernel version - 2.6.31 .Everything was done with gentoo handbok

You can see this error on screen: http://img576.imageshack.us/img576/7076/99045197.jpg

Now i dont know how to fix thix error :/. Even if I have mounted liveCD in Vmware I cant enter any command (get kernel panic and then my screen freeze). I think that fstab and lilo was configured properly... Can anyone help me

?? Meyby I should use genkernel ...? (this is my first linux but im not noob;p). Meyby I'll try LiveCD with GUI instalation

What does your lilo configuration look like?

How Can I check my lilo conf

?? My screen freeze after this kernel panic screen :/. Must I use liveCD? Or there is other way to get to lilo conf?

No, you must use the LiveCD to check your lilo config

All my configuration pasted. I have one more problem after reboot = when I try mount /mnt/gentoo/proc and /mnt/gentoo/dev I got error "mount point not exist" but earlier I mounted those folders - when I used rescueCD I got this error. Of couse when I use mkdir /mnt/gentoo/dev and then /mnt/gentoo/proc everything is ok but this is not good way I think

??

Lilo conf

boot=/dev/sda
prompt
timeout=10

image=/boot/kernel-2.6.31
label=gentoo
read-only
root=/dev/sda3

image=/boot/kernel-2.6.31
labe=gento.rescue
read-only
root=/dev/sda3
append="init=/bin/bb"

Fdisk:

/dev/sda1 -linux
/dev/sda2 -swap
/dev/sda3 -linux

Fstab conf

//dev/sda1 /boot ext2 defaults,noatime 1 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext3 noatime 0 1

It sounds to me that your kernel is missing something. Are you using genkernel or a custom kernel?

Im using custom kernel

(first time installing gentoo...). Meyby I missed some modules in kernel configuration?? But which and how can I check with module I missed and how add it?? How can I check my kernel config (and paste it here?)?

Smal update : When I try to run kernel-nofb from LiveCD I got badly error : error running /sbin/depscan.sh .... Anyway how can I log into system live CD :F? (default user and passwd??) . When I entered "root" and no password entered I got message "login incorect". Also I got this message "this is (none).unknown_domain none login"

Have a look at this, it might help you get your kernel going

Ok I will try but why when I choice kernel-nofb after choose keymap I got message : cp write error - np space left on devices adn then error running /sbin/depscan.sh ?? Any Idea?? On Vmware I can only have 1880 RAM max :/ - I think this error is linked with ram size... Any idea??

Zaboleq,

Your original error, unknown-block(8,3) tells that the kernel can recah your hard drive but not read the filesystem it finds there.
Either the kernel module for your root filesystem has been mad as <M> so it can't be loaded until root is mounted (think about that) or its not been included in the kernel at all. It must be <*>

If needed:
boot cd
mount the gentoo partitions
run

I just went through this. Are you using a HDD with the SCSI device on VMWare? if you are then you need to add the Fusion MPT device so it can detect the HDD

I used to run Gentoo Linux inside VMWare Player in the past and I have had this exact problem too. The solution is to compile your kernel with the correct sata/scsi controller drivers. I forget which ones are the ones you need, but it is likely listed at the unofficial wiki, to which someone posted a link in this thread earlier:

http://en.gentoo-wiki.com/wiki/Virtualbox_Guest

That was how I managed to fix this problem when I had it.

In the linux kernel menuconfig you need to pick
Device Drivers -> Fusion MPT device support -> Fusion MPT ScsiHost drivers for SPI
not as modules but as part of the kernel
