[Fedora-xen] no sda1 in DomU

hi,

I try to get the Centos.5-1.64 image from Jailtime.org running in a
Centos5 / Fedora8 Dom0, but it complains that there''s no sda1 in the
DomU. I tried both file- and lvm-backed VBDs, but with no luck:

[...]
Initializing IPsec netlink socket
NET: Registered protocol family 1
NET: Registered protocol family 17
XENBUS: Device with no driver: device/vbd/2049
XENBUS: Device with no driver: device/vbd/2050
XENBUS: Device with no driver: device/vif/0
md: Autodetecting RAID arrays.

VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

configfile looks like this:

kernel = "/boot/vmlinuz-2.6.18-53.1.14.el5xen"
memory = 256
name = "myzel"
vif = [ '''' ]
dhcp= "dhcp"
disk = [''phy:vg_virtual/lv_myzel_root,sda1,w'',
''phy:vg_virtual/lv_myzel_swap,sda2,w'']
# disk = [''tap:aio:/virtual/centos.5-1.64.img,sda1,w'',
''tap:aio:/virtual/centos.swap,sda2,w'']
root = "/dev/sda1"
extra = "fastboot"

(I also tried device name xvda, but to no avail)

Dom0 kernel:
Linux xenserv 2.6.18-53.1.14.el5xen #1 SMP Wed Mar 5 12:08:17 EST 2008 x86_64
x86_64 x86_64 GNU/Linux

any help appreciated. xend.log excerpt and DomU dmesg follows:

Re: [Fedora-xen] no sda1 in DomU

Well, I suspect your disk parameters are simply wrong...

disk =
[''phy:vg_virtual/lv_myzel_root,sda1,w'',''phy:vg_virtual/lv_myzel_swap,sda2,w'']
-This one seems to be messing / or /dev before vg_virtual.

disk = [''tap:aio:/virtual/centos.5-1.64.img,sda1,w'',
''tap:aio:/virtual/centos.swap,sda2,w'']
-This one I''m not sure, but I use "file:/", have you tried it
like below?

disk = [''file:/virtual/centos.5-1.64.img,sda1,w'',
''file:/virtual/centos.swap,sda2,w'']

Re[2]: [Fedora-xen] no sda1 in DomU

hi,

II> create a initrd with xenblk module

big thanks for the hint - I created the initrd by using

mkinitrd -v -f --preload=ext3 --preload=xenblk --preload=xennet
--omit-raid-modules --omit-lvm-modules --omit-scsi-modules 
/boot/initrd-2.6.18.xenU.img  `uname -r`

the VM boots now, but hangs after starting the crond:

[...]

... hangs here ...

also, although the network is configured properly, the interface can''t
be pinged.

a "xm shutdown myzel" shuts down the VM properly (vm console shows
shutdown messages and finally terminates).

do I need to put any additional modules into the initrd ?

tnx in advance.

Re[2]: [Fedora-xen] no sda1 in DomU

II> boot in single user mode, start network and update your linux with yum

ok, I''m now one step further:

- can boot into single user mode
- all block devices are mounted in the VM
- network starts properly, yum update loaded & applied some updates
- sshd starts, I can ssh into the vm from outside.

dmesg shows some strange messages:
XENBUS: Device with no driver: device/vbd/2049
XENBUS: Device with no driver: device/vbd/2050
XENBUS: Device with no driver: device/vif/0
Floppy drive(s): fd0 is unknown type 15 (usb?), fd1 is unknown type 15 (usb?)
Failed to obtain physical IRQ 6
floppy0: no floppy controllers found
lp: driver loaded but no devices found

my assumption: the VM can''t connect to the console or some tty or
whatever because of the missing drivers what means that the login prompt
doesn''t show.

I exaleaded for the messages and found some threads with the same
problem, but without solution:
