Hello list,
I am just at the beginning of installing Xen. After two days of trying I
finally managed to boot the xen0 kernel. Now I am trying to create my first
domain. Since the system is a Raid system, I know there is a problem with my
root entry (I had these problems with the xen0 kernel as well in the
beginning) I receive this error message when trying to create the domain
with "xm create -c xmjan1 vmid=1" (system is FC4 on Dell 450 WS, 2 CPUs,
SATA Raid, 2GB RAM):
--------------------------8<---------------------------------

The config file looks as follows:
---------------------8<--------------------------------
# Kernel image file.
kernel = "/boot/vmlinuz-2.6.12.6-xenU"
# Optional ramdisk.
ramdisk = "/boot/xen-3.0.jan.img"
# The domain build function. Default is 'linux'.
#builder='linux'
# Initial memory allocation (in megabytes) for the new domain.
memory = 128
# A name for your domain. All domains must have different names.
name = "FirstDomain"
# Which CPU to start domain on?
#cpu = -1 # leave to Xen to pick
# Number of Virtual CPUS to use, default is 1
#vcpus =
1
#----------------------------------------------------------------------------
# Define network interfaces.
# Number of network interfaces. Default is 1.
#nics=1
# Optionally define mac and/or bridge for the network interfaces.
# Random MACs are assigned if not given.
#vif = [ 'mac=aa:00:00:00:00:11, bridge=xenbr0'
]
#----------------------------------------------------------------------------
# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.
disk = [ 'phy:/dev/sda2,/dev/sda2,w'
]
#----------------------------------------------------------------------------
# Define to which TPM instance the user domain should communicate.
# The vtpm entry is of the form 'instance=INSTANCE,backend=DOM'
# where INSTANCE indicates the instance number of the TPM the VM
# should be talking to and DOM provides the domain where the backend
# is located.
# Note that no two virtual machines should try to connect to the same
# TPM instance. The handling of all TPM instances does require
# some management effort in so far that VM configration files (and thus
# a VM) should be associated with a TPM instance throughout the lifetime
# of the VM / VM configuration file. The instance number must be
# greater or equal to 1.
#vtpm = [ 'instance=1,backend=0' ]
#----------------------------------------------------------------------------
# Set the kernel command line for the new domain.
# You only need to define the IP parameters and hostname if the domain's
# IP config doesn't, e.g. in ifcfg-eth0 or via DHCP.
# You can use 'extra' to set the runlevel and custom environment
# variables used by custom rc scripts (e.g. VMID=, usr= ).
# Set if you want dhcp to allocate the IP address.
dhcp="dhcp"
# Set netmask.
#netmask=
# Set default gateway.
#gateway=
# Set the hostname.
#hostname= "vm%d" % vmid
# Set root device.
root = "/dev/mapper/VolGroup00-LogVol00 ro"
# Root device for nfs.
#root = "/dev/nfs"
# The nfs server.
#nfs_server = '169.254.1.0'
# Root directory on the nfs server.
#nfs_root = '/full/path/to/root/directory'
# Sets runlevel 4.
extra = "4"
-----------------------------------8<-----------------------
Can anyone point me to a solution, e.g. where to look to determine the
correct root drive/dev in a Raid system? Since this is my first machine with
a Raid system installed, I am a bit stuck here...
Thanks in advance
Jan
