I failed pretty much at the first hurdle with this guide.
== Serial console and kernel parameters (to fix console hanging) ==


I'm guessing that stage3 has to be unpacked into the target directory ('''/mnt/gentoo'''), but the guide doesn't specify.
I had to do the following on my image to get the serial console to work:<br>
echo "hvc0:2345:respawn:/sbin/agetty -L 9600 hvc0" >> /mnt/etc/inittab<br>
echo  hvc0 >> /mnt/etc/securetty


Where does '''mirrorselect''' come from? This looks like a Gentoo package but I can't find it for Debian thus can't install it in the [[rescue environment]].
I also needed to add "console=hvc0 xencons=tty" to my list of kernel parameters:<br>
kernel /boot/vmlinuz root=/dev/xvda1 console=hvc0 xencons=tty


I didn't get any further than that, but some other thoughts:
==PVH mode==
Since the kernel is now new enough it would be good to have Gentoo guests run in [[PVH]] mode. All that needs to be done is:


* What's the point of splitting xvda into '''/boot''' and '''/''' if they are both going to be the same filesystem type ('''ext4''' in this case)? Normally the only point in having a separate '''/boot''' on a VPS is if you want to use something more exotic like '''btrfs''' or [[LVM]] for your root.
* enable <code>PCI</code>, <code>XEN_PVHVM</code> and <code>ACPI</code>
* is '''--f-omit-frame-pointers''' a safe '''CFLAG'''?
* enable <code>CONFIG_XEN_PVH</code> in the kernel (as well as <code>CONFIG_XEN_PV</code> for now)
* install that kernel
* shut down
* <code>xen shell> virtmode pvh</code>
* <code>xen shell> boot</code>

No reason why it shouldn't Just Work but if it doesn't, switch back to PV mode.


In response.... Doing this in abstracted way (on a Xen VM at Home prior to moving it to Bitfolk).  You don't need grub.  Mirrorselect is from the Gentoo CD.  Just use something sensible in /etc/portage/make.conf
Could a Gentoo user please give this a try and update the article?

I see little point in having a seperate /boot.  Especially as /boot just contains a kernel and grub config if you don't use genkernel.

Thanks Andy and Jon, I've made some edits in light of what you said. Hopefully it's more correct

Serial console and kernel parameters (to fix console hanging)

I had to do the following on my image to get the serial console to work:
echo "hvc0:2345:respawn:/sbin/agetty -L 9600 hvc0" >> /mnt/etc/inittab
echo hvc0 >> /mnt/etc/securetty

I also needed to add "console=hvc0 xencons=tty" to my list of kernel parameters:
kernel /boot/vmlinuz root=/dev/xvda1 console=hvc0 xencons=tty

PVH mode

Since the kernel is now new enough it would be good to have Gentoo guests run in PVH mode. All that needs to be done is:

  • enable PCI, XEN_PVHVM and ACPI
  • enable CONFIG_XEN_PVH in the kernel (as well as CONFIG_XEN_PV for now)
  • install that kernel
  • shut down
  • xen shell> virtmode pvh
  • xen shell> boot

No reason why it shouldn't Just Work but if it doesn't, switch back to PV mode.

Could a Gentoo user please give this a try and update the article?
