Alright, I think you understand the issue, your kernel is using IDE drivers to access PATA devices, resulting nodes were /dev/hd*. It worked this way until newer udev version stopped supporting hd* nodes. Your Gentoo still boots but cannot see /boot and swap. To verify this theory you should hit e at Grub boot menu and review the kernel command line or simply do cat /proc/cmdline.
If my theory is correct then to fix it you should get access to /boot to install a new properly configured kernel. Maybe it is as easy as changing kernel command line from Grub screen. If it does not work you should either:
1. boot this VM from a Linux CD and chroot
2. or you should create missing hda* nodes by hand. Maybe downgrading udev will work, too.

But first things first, what is your kernel command line?

Can you use wgetpaste and put your entire dmesg into pastebin, the dmesg you posted earlier wasn't complete.
Output of lspci -k would be helpful, too.

Well, all drivers seem correct, for some reason dmesg is not what it should be ... is udev in sysinit runlevel?

could it be a reason where i had manually added eth0 in the past as net.lo failed to get the static IP assigned? since then on reboot i get a warning saying, this array feature will be deprecated in future?

Just trying to join sides together.

After udev restart, do you have /dev/sda* nodes now?

I'm running out of ideas, the early part of dmesg is missing, did you examine /var/log/messages ?

Hi Jaglover and John,
sorry I was away so couldn't reply. I have rechecked my other gentoo VM and there seems to be a difference in kernel driver (ata vs. piix).
Affected VM for which this thread is opened:
Code:

~ # eselect kernel list

So it is the IDE driver as I suspected. You could create hda1 device node by hand (major 3 minor 0 methinks), mount /boot and upgrade your kernel.

i have never played around with kernels (mknod etc) as genkernel has been working fine so far (until i hit this kernel driver piix issue).
pls could you detail your process, and ya thanks again for your time.

this is what i have tried :
Code:

~ # mknod /dev/hda1 b 3 0
~ # mount /boot
mount: special device /dev/sda1 does not exist
~ # mount /dev/hda1 /boot
mount: no medium found on /dev/hda1
~ # ls -al /dev/h
hda1  hpet
 ~ # ls -al /dev/s
sg0       shm/      snapshot  stderr    stdin     stdout

~ # genkernel all

* Running with options: all

* Linux Kernel 3.3.8-gentoo for x86...

okay, after all the tries, i have tried downgrading the udev but still no joy:

Code:

* Messages for package sys-fs/udev-164-r2:

 *
 * udev-164 does not support Linux kernel before version 2.6.25!
 * For a reliable udev, use at least kernel 2.6.27
 *
 * Updating persistent-net rules file
 *
 * persistent-net does assigning fixed names to network devices.
 * If you have problems with the persistent-net rules,
 * just delete the rules file
 *      rm /etc/udev/rules.d/70-persistent-net.rules
 * and then reboot.
 *
 * This may however number your devices in a different way than they are now.
 *
 * If you build an initramfs including udev, then please
 * make sure that the /sbin/udevadm binary gets included,
 * and your scripts changed to use it,as it replaces the
 * old helper apps udevinfo, udevtrigger, ...
 *
 * mount options for directory /dev are no longer
 * set in /etc/udev/udev.conf, but in /etc/fstab
 * as for other directories.
 *
 * If you use /dev/md/*, /dev/loop/* or /dev/rd/*,
 * then please migrate over to using the device names
 * /dev/md*, /dev/loop* and /dev/ram*.
 * The devfs-compat rules have been removed.
 * For reference see Bug #269359.
 *
 * Rules for /dev/hd* devices have been removed
 * Please migrate to libata.

Code:
~ # mount /dev/hda1 /boot
mount: no medium found on /dev/hda1


So it is not 3,0 ... let me Google ... here it is ...

Code:
mknod hda b 3 0
mknod hda1 b 3 1

sorry to be a pain jaglover. after I created the nod on 3 1 then it says the same as sda1
Code:

~ # mknod hda b 3 0
~ # mknod hda1 b 3 1
~ # mount /dev/hda1 /boot
mount: special device /dev/hda1 does not exist

Alright this approach seems not to be working.
As I stated before I've no clue how vmware works.
A simple way to fix it with regular Gentoo install is to boot from a Linux liveCD and chroot. There has to be a way to boot this VM from a CD or CD image. I just do not know how.
