3:05 p.m.
I want to use the stock Fedora cloud image,
Fedora-x86_64-20-20131211.1-sda.raw. Dom0 is also Fedora 20, running the
Xen kernel. I've yum update'd everything.
I have downloaded a local copy of the .raw file.
I've created a user-data file containing:
==================
#cloud-config
password: fedora
chpasswd: {expire: False}
ssh_pwauth: True
==================
And a meta-data file containing:
==================
instance-id: build-f20; local-hostname: build-f20
==================
I create an iso image of these with:
# genisoimage -output build-f20-cidata.iso -volid cidata -joliet
-rational-rock user-data meta-data
Then I try to install the image with:
# virt-install --import --name build-f20 --ram 512 --vcpus 1 --disk
path=./Fedora-x86_64-20-20131211.1-sda.raw,bus=scsi --disk
build-f20-cidata.iso,device=cdrom,bus=scsi --network
bridge=virbr0,model=virtio --graphics=none
After a number of output lines, I get the error:
[ 1.268756] VFS: Cannot open root device
"UUID=e78f2b16-8836-4e6a-9e5e-fdc6c9d3cfc3" or unknown-block(0,0): error -6
(Full --debug output at the end of the email).
I've verified that this error comes from the UUID that's in
/boot/extlinux/extlinux.conf, but everything looks correct there. I've
verified that this is the volume's UUID with
# guestfish -a Fedora-x86_64-20-20131211.1-sda.raw << EOF
run
vfs-uuid /dev/sda1
EOF
e78f2b16-8836-4e6a-9e5e-fdc6c9d3cfc3
If I don't include the iso image, then after the VFS error line I get:
Please append a correct "root=" boot option; here are the available
partitions:
with no partitions listed.
I'm at a loss as to what to try next. I suspect it has something to do
with the /dev/sda1 vs. sda in the XML (which follows in the debug
output), but I'm not sure what to do about it. Any suggestions?
I've been unable to find any documentation on how to use the stock F20
image while running Dom0 as F20. Any pointers appreciated.
Thanks.
Eric.

==================
And a meta-data file containing:
==================
instance-id: build-f20; local-hostname: build-f20
==================
I create an iso image of these with:
# genisoimage -output build-f20-cidata.iso -volid cidata -joliet
-rational-rock user-data meta-data
Then I try to install the image with:
# virt-install --import --name build-f20 --ram 512 --vcpus 1 --disk
path=./Fedora-x86_64-20-20131211.1-sda.raw,bus=scsi --disk
build-f20-cidata.iso,device=cdrom,bus=scsi --network
bridge=virbr0,model=virtio --graphics=none
After a number of output lines, I get the error:
[ 1.268756] VFS: Cannot open root device
"UUID=e78f2b16-8836-4e6a-9e5e-fdc6c9d3cfc3" or unknown-block(0,0): error -6
(Full --debug output at the end of the email).
I've verified that this error comes from the UUID that's in
/boot/extlinux/extlinux.conf, but everything looks correct there. I've
verified that this is the volume's UUID with
# guestfish -a Fedora-x86_64-20-20131211.1-sda.raw << EOF
> run
> vfs-uuid /dev/sda1
> EOF
e78f2b16-8836-4e6a-9e5e-fdc6c9d3cfc3
If I don't include the iso image, then after the VFS error line I get:
Please append a correct "root=" boot option; here are the available
partitions:
with no partitions listed.
I'm at a loss as to what to try next. I suspect it has something to do
with the /dev/sda1 vs. sda in the XML (which follows in the debug
output), but I'm not sure what to do about it. Any suggestions?
I've been unable to find any documentation on how to use the stock F20
image while running Dom0 as F20. Any pointers appreciated.
Thanks.
Eric.

I realize the question I'm asking might be too specific for any advice.
But does anyone have any general debugging suggestions? I'm more than
willing to put in time to try and solve this. I think it's important
that the stock Fedora cloud image be able to be used in this scenario,
and I've found scant information about it online. Once I have it
working, I'll produce some text on how to get it working so that others
can more easily use and test the cloud image.

Hmm, "bus=scsi"? Although this is Xen, this seems to be a surprising
choice. I would have thought bus=xen (or possibly bus=virtio) would
work better.
If you look at the guest kernel output, you can see that no sda hard
disk device is detected at all, which would mean that the guest
doesn't have the right device drivers to see this sort of disk. And
since there is no model=... in the libvirt XML I'm not even sure what
device driver would be required here. Xen probably chooses a default
SCSI device to emulate.

Thanks for looking at this.
I should have mentioned that I tried multiple bus= options, and got the
same results. The last one was =scsi, so that's what I posted. At the
end of this is the debug output with bus=xen, but I have the same VFS
error there.
virtio I had apparently not tried. I get a different error with that:

I'd expect to see the hard disk being seen by the guest, ie. a
message similar to this in the kernel output:

If you're not seeing something like that, then something very
low-level is going wrong about how the disk is presented to the guest.
This is possibly a libvirt or Xen issue.

It isn't obvious from the logs but pygrub isn't parsing the extlinux block
label Fedora-x86_64-20-20131211.1 (3.11.10-301.fc20.x86_64)
kernel /boot/vmlinuz-3.11.10-301.fc20.x86_64
append ro root=UUID=e78f2b16-8836-4e6a-9e5e-fdc6c9d3cfc3 console=tty1
console=ttyS0,115200n8
initrd /boot/initramfs-3.11.10-301.fc20.x86_64.img
as desired as it doesn't seem to understand the initrd line, hence xen tries to boot
the image without the initramfs file and not surprisingly it fails.
