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.
