Here is my setup /dev/sda1 / ext3 noatime 0 1 /dev/sda2 swap grub is installed using the 'root (hd0,0)' and 'setup (hd0)', no problem. emerge kernel-sources worked fine. However everytime the system boots, it reports the VFS panic (no root system found problem). The kernel has built in ext2 and ext3 support. The error hint is to supply root option during boot, but my boot command is this kernel /boot/kernel root=/dev/sda1 Is there something missing that I didn't think of that's causing the failures?

snip VFS: Cannot open root device sda1 or unknown-block(0,0) Please append a correct root= boot option; here are the available partitions: Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0) /snip (hey, I remembered not to top post for once!) Not that this hasn't been said, but this is almost definitely a device driver issue. In my experience (and I've had this and similar errors on many systems), when it's a file system problem (i.e. having the correct FS driver compiled in), you get unknown-block(x,y) where x,y are both nonzero. That said, something definitely needs to be changed with your kernel config. I run several vmware servers (the free server), and have gentoo VMs on those. If you'd like, I can post my .config for you to compare. Or I could just look through the scsi options I have configured. When I configured my VMs, I remember reading the following article: (along with some trial and error, of course.) http://gentoo-wiki.com/HOWTO_Install_Gentoo_on_VMware_in_Windows_NT/2K/XP#Kernel_Configuration -- Greg Postscript: As this is an error mouting your root file system, the fstab, which is stored on the root file sysem, doesn't matter at this point in the boot process.
