RE: Urgent Help Required: FC10 as DomU on FC8 as Dom0

[MOHAMMAD MATEEN ASLAM]

I have FC8 running as dom0 and i want to install FC10 as domU. I have installed
python-virtinst-0.300.2-5.fc8 from fedora standard repo on FC8. But still i am unable to
boot FC10 kernel on FC8. 

Following error comes when I  try to boot F10 with Ramdisk created on FC8/ Dom0. 

# xm create -c xxx.cfg

How to boot FC-10 as domU on FC8?  I will appreciate help from xen experts.

The relevant doc is:
http://fedoraproject.org/wiki/Docs/Beats/Virtualization

More specifically:
http://fedoraproject.org/wiki/Docs/Beats/Virtualization#Xen_Updated_to_3.3.0

Fedora 8 would need pretty much all of its Xen-related packages updated 
to be able to handle the new F10 pv_ops kernel as a domU.  I believe 
there was discussion about building such packages and leaving them in 
the testing repo for F8 (i.e. not pushing them out before EOL) but I 
don't remember what came of it.  Search the list for more details.

The short answer is pretty much use KVM instead or roll-your-own from 
upstream to get a dom0 that works with Fedora 10 as a domU.

Urgent Help Required: FC10 as DomU on FC8 as Dom0

[MOHAMMAD MATEEN ASLAM]

Hi Aaron,

Thanks for quick help. Infact my current network architecture dont allow me to upgrade
quickly to KVM. My FC8 is fully updated with standard update repo, but not from test repo.
Is there any difference between standard repo versions and test repo versions ? My FC8
have the same python-vertinst version which was in test repo.

Regards
Mohammad Mateen

"python-virtinst-0.300.2-5.fc8 has been pushed to the Fedora 8 stable
repository.  If problems still persist, please make note of it in this bug
report."

So the python-virtinst you have should be OK.

Are you sure your ramdisk/initrd is correct? based on the output you pasted
it seems your initrd image is not working correctly..

Have you tried installing F10 domU with the installer?

[MOHAMMAD MATEEN ASLAM]

Hi Pasi,

Thanks for helping. Yes, apparently, the problem looks in Ramdisk. I have created Ramdisk
with following command but it is unable to boot FC10:-

mkinitrd -f --builtin=xenner --preload=xenblk --builtin=ehci-hcd --builtin=ohci-hcd
--builtin=uhci-hcd --builtin=ahci
--builtin=ata_piix /boot/initrd-2.6.27.7-134.fc10.i686.PAE-domU.img
2.6.27.7-134.fc10.i686.PAE
if i dont mention these modules  "--builtin=xenner --builtin=ehci-hcd
--builtin=ohci-hcd --builtin=uhci-hcd --builtin=ahci --builtin=ata_piix"  i got
following errors.
No module xenblk found for kernel 2.6.27.7-134.fc10.i686, aborting.
No module ehci-hcd found for kernel 2.6.27.7-134.fc10.i686, aborting.
No module ohci-hcd found for kernel 2.6.27.7-134.fc10.i686, aborting.
.....

I have also try to use Fedora 10 Ramdisk instead of re-creating but VM halt few steps
earlier giving these errors:-

xenner is something you use on a KVM host to emulate Xen.. I think you
shouldn't need/use xenner with the real Xen. And especially not in domU,
xenner is for KVM "dom0".

This means xen block/disk device (xvd) driver was not loaded.

This means xen network driver was not loaded.

Does your kernel contain those modules? or are they built-in in the pv_ops
kernels?

So.. just to get it correctly:

1. You installed Fedora 8 domU 
2. You updated Fedora 8 domU to Fedora 10 (on the fly) with yum
3. You create initrd image for the F10 kernel using the mkinitrd command above

That should work.. assuming you get the initrd correct. 

You could also try installing a fresh F10 domU (with virt-install or
virt-manager) and see if that works..

True, xenner is also required for KVM. I have used xenner module successfully for my old
FC8 (DomU) and it worked fine. On your advice I have tried to created RamDisk without
xenner but no luck.

This seems sound, i am using Latest FC10 kernel -2.6.27.7-134.fc10.i686.PAE as DomU and
Latest kernel 2.6.21.7-5.fc8xen on FC8 (Dom0). Ideally FC10 pv_ops kernel should have
these modules support, either built-in or as module.

Yes you got exactly right,  logically it should work, but its not working.

I am checking fresh installation via virt-install on another box with same setup. I will
post results here.

It worked
for me using the vmlinuz-PAE and and initrd-PAE.img files from 
the DVD image (in the images/pxeboot directory). I suggest you retry 
with these in case there was some problem with the ramdisk you created.
The python-virtinst version shouldn't matter if you are installing using 
xm and a configuration file, but the xen package does need to be updated 
to the latest fc8 version.

Do you successfully install and boot FC10 as DomU  on FC8 box?

Should that be xvda rather than sda? I think xvda is required in some 
situations. I am not familar with the tap:aio: prefix either, I would have 
expected something like file: but as I mostly map partitions to disks or 
partitions it isn't an area I am expert it.

Support for hijacking SCSI/IDE device names was ripped out of the
Xen blkfront when it was merged in upstream Linux. Since Fedora 10
guest is based on upstream, you need to use xvda not sda, regardless
of installer. 

We did warn people this would likely happen when upstream got hold
of the code...

Thanks Daniel, my problem resolved by using xvd* instead of sda.

Urgent Help Required: FC10 as DomU on FC8 as Dom0

Hi Pasi,

I successfully booted FC10 kernel (DomU) on FC8 (Dom0) by changing sda with xvd*.  

Thanks alot for your and Young help. This is how community works.

Your disk configuration is wrong. 

You need to have xvda disk for domU.

Something like this:

disk = ['tap:aio:/var/xen/vm13/xvda,xvda,w']

if 'tap:aio' doesn't work, then try just 'file'.

Have you tried installing with virt-install? or virt-manager? 

Example how I installed rawhide on CentOS 5.2 dom0:
(NOTE: This was earlier, before Fedora 9 was released. I haven't tried it now for F10
or F11 rawhide)

$ virt-install -n test -r 512 --vcpus=1 -f /dev/vg0/test_disk1 --vnc -p -l
"ftp://ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/development/i386/os"

Replace the FTP mirror with your local mirror.

Does that work?

.. The reason you upgraded python-virtinst is to be able to use
virt-install and/or virt-manager ..
