Hi

I am trying out the PV-GRUB boot and having some problems.

Stock Fedora 15 build with kernels:

GNU GRUB version 0.97 (1048576K lower / 0K upper memory)

+-------------------------------------------------------------------------+
| Fedora (2.6.41.4-1.fc15.i686.PAE) |
| Fedora (2.6.38.6-27.fc15.i686.PAE) |
| |
| |

I selected the pv-grub-x86_32 kernel and made sure /dev/xvda was root:

I get this when I try to boot:

Code:
Booting 'Fedora (2.6.41.4-1.fc15.i686.PAE)'
[linode156033@dallas422 lish] !p
    Press enter to boot the selected OS, 'e' to edit the
  Booting 'Fedora (2.6.41.4-1.fc15.i686.PAE)'

root (hd0)
 Filesystem type is ext2fs, using whole disk
kernel /boot/vmlinuz-2.6.41.4-1.fc15.i686.PAE root=/dev/xvda console=tty0 conso
le=hvc0 ro
initrd /boot/initramfs-2.6.41.4-1.fc15.i686.PAE.img

close blk: backend at /local/domain/0/backend/vbd/373/51712
close blk: backend at /local/domain/0/backend/vbd/373/51728


Both kernels return the same output with no errors but don't boot and return a failed boot. Anyone have any ideas?

Thanks

I had the same issue a few minutes ago the boot hung at that point, I shutdown and booted up again via the linode manager and it worked the second time (note the close blk: bits aren't errors they're normal)

[jamesturnbull]

I've tried a few times. I know the blk bits are normal but I get zero additional output in lish or via logview. Very strange.

Ah just spotted your problem, edit console=tty0 to console=hvc0

[jamesturnbull]

Nope sadly not. Tried that:

Code: # boot=/dev/xvda
# kopt=root=/dev/xvda console=hvc0 ro quiet
# groot=(hd0)

default=0
timeout=5

And no joy.

Can you ssh in normally or ping your server so we can tell if it's actually booting and not displaying the list console or just not booting properly at all.

It's not booting at all. Can't ping or SSH to it and when it fails it drops me out of the Lish screen session.

Well that's about as much as I know about fedora without trying it myself hopefully someone else who uses fedora will pop up and be able to help.

[jamesturnbull]

No problems - thanks for trying. :)

It's weird because there's no error output which makes troubleshooting somewhat tricky.

Cheers

I assume you've had a read of this? http://library.linode.com/linode-platform/custom-instances/pv-grub-howto#sph_fedora-15

That's what I based my config on.

I have the same issue with Centos 6.2.
The strange part is that it works on one linode (newark405) and not on another (newark394).

I think it's a problem with the hosting machine, not with the linode

[jamesturnbull]

It might be but difficult to test that. I am just disappointed I can't seem to get it working.
