I am working on a GenToo install via VMware Workstation 10. I have been following the wiki handbook and have been able to get to the first reboot after "Configuring the bootloader". I did have an issue on first boot where it would boot to a GRUB command prompt, but i have corrected that issue. However, now i am getting:
Code:
Kernal Offset: disabled

Code:
Kernal panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)


I have tried googling this issue, but i haven't been able to find relavent information using a VM. Also, I am still extremely new at Linux and GenToo, so I am still learning my way with how linux installs and operates. I was hoping I could find a resolution to this on my own, but unfortunately my understanding of Linux and its commands is just not there yet.

Please let me know any information regarding my build thus far that would assist with troubleshooting this.

Thanks in advance for any advice!!

Razor0068,

The message
Code:
unknown-block(0,0)
normally means that you have a piece of the kernel missing that is needed to reach your emulated HDD.

I don't use VMware Workstation here but a favourite problem was putting root on a MPT Fusion SCSI device than not having the driver in the kernel.
Its on its own menu, so its easy to miss.

Start your boot media in VMware Workstation, run
Code:
lspci -k
and post the result.
wgetpaste is your friend.

I have gone through my kernal several times and searched for kernal configs recommended for virtual machines/VMware, but it is very possible ive still missed something. What is the driver i need to search for?


The results of your command are linked below:

Razor0068,

You have two pieces of emulated hardware that you can attach emulated HDD to.
Code:
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
        Subsystem: VMware Virtual Machine Chipset
        Kernel driver in use: ata_piix

and
Code:
00:10.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 01)
        Subsystem: VMware LSI Logic Parallel SCSI Controller
        Kernel driver in use: mptspi
        Kernel modules: mptspi


Its likely that you have ata_piix configured correctly as its in the usual location with evenything else on the SATA menu.
mptspi is harder to find.
Code:
  │ │    < > ATA/ATAPI/MFM/RLL support (DEPRECATED)  ----                 │ │ 
  │ │        SCSI device support  --->                                    │ │ 
  │ │    <*> Serial ATA and Parallel ATA drivers (libata)  --->           │ │ 
  │ │    [*] Multiple devices driver support (RAID and LVM)  --->         │ │ 
  │ │    < > Generic Target Core Mod (TCM) and ConfigFS Infrastructure  --│ │ 
  │ │    [ ] Fusion MPT device support  ----
Its in the Fusion MPT device support menu.
