Hello.
I can't start Virtual Machine, have the message:
Waiting for root file system ... done.
Gave up waiting for root device. Common problems

ALERT! /dev/xvda2 does not exist. Dropping to a shell!
I have installed Xen 4 in a debian squeeze:
# uname -a
2.6.32-5-xen-amd64 #1 SMP Wed Jan 12 05:46:49 UTC 2011 x86_64
GNU/Linux
xen-hypervisor-4.0-amd64 4.0.1-2
The
Xen Hypervisor on AMD64
I have created the virtual machine with this command:
# xen-create-image --size=2Gb --swap=128Mb --dhcp --dist=stable
--dir=/home/xen --hostname=debian
My debian.cfg is:
kernel = '/boot/vmlinuz-2.6.32-5-xen-amd64'
ramdisk = '/boot/initrd.img-2.6.32-5-xen-amd64'
vcpus = '1'
memory = '128'
root = '/dev/xvda2 ro'
disk = [
'file:/home/xen/domains/debian2/disk.img,xvda2,w',
'file:/home/xen/domains/debian2/swap.img,xvda1,w',
]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
In my Server the filesystem is /dev/sda1.
I have tried with:
root = '/dev/xvda1 ro'
root = '/dev/sda1 ro'
root = '/dev/sda2 ro'
And the same problem
In the /dev vm I have:
(initramfs) ls /dev
char console core cpu_dma_latency fd full hvc0 hvc1 hvc2 hvc3 hvc4
hvc5
hvc6 hvc7 input kmsg mapper mem network_latency network_throughput
null
port psaux ptmx pts random snapshot ttyx urandom vcs vcs1 vcsa vcsa1
vga_arbiter xen zero
I have tried with vcs vcs1 vcsa vcsa1 but have the error:
mount: mounting /dev/vcs1 on /root failed: No such file or directory
Any idea? I'm making wrong something?
A lot of thanks!
Does /dev/xvda1 exist?
No, only vcs, vcsa and sda
Is the frontend block device driver compiled as a
module?
I have installed xen from aptitude install. I didn't configured frontend
block device driver, should I?

Hi , what's in the log of the vm ( like
/var/log/xen/qemu-dm-debian.log ) ?
And in the xend.log ?
Hello, I can't see nothing in the logs. I upload in ompldr.org:
http://ompldr.org/vN2Ridg/domain-builder-ng.log
http://ompldr.org/vN2Ridw/xend.log
Thanks!
it indeed create your disks as vcsa1 and vsca2 :
createDevice: vbd : {'uuid': 'c5fb4564-05e6-8323-97f6-1ecbc43ab0f8',
'bootable': 1, 'driver': 'paravirtualised', 'dev': 'vcsa1', 'uname':
'file:/home/xen/domains/debian2/disk.img', 'mode': 'w'}
Here's one of mine :
createDevice: vbd : {'uuid': 'feaa1b2d-3017-e010-ec5d-2a612826e5bd',
'bootable': 0, 'driver': 'paravirtualised', 'dev': 'xvdb1', 'uname':
'phy:vg0/erp5', 'mode': 'w'}
