[Xen-users] cm create produces -> Error: int argument required
Hi,
I''m very new to this whole Xen stuff; I''m still on an
incredible
learning curve and am experiencing an error I just can''t seem to solve.
When I run:
$>xm create -c /var/xen/guests/test-vm.cfg vmid=1
I get:
Using config file "/var/xen/guests/test-vm.cfg".
Error: int argument required
$> xm dmesg

I don''t understand enough about linux to have any clue as to what that
means. So I''m just going to drop on my knees and hope you
oracle''s have
the answer :-).
Here is my configuration file:
$> cat /var/xen/guests/test-vm.cfg

# Kernel image file.
kernel = "/boot/vmlinuz-2.6.21-2950.fc8xen"
# Virtual Hardrive Root
root = "/dev/hda1"
# Optional ramdisk.
#ramdisk = "/boot/initrd.gz"
# The domain build function. Default is ''linux''.
builder=''linux''
# Initial memory allocation (in megabytes) for the new domain.
memory = 64
# A name for your domain. All domains must have different names.

# 128-bit UUID for the domain.

# List of which CPUS this domain is allowed to use, default Xen picks
#cpus = "" # leave to Xen to pick
#cpus = "0" # all vcpus run on CPU0

#-----------------------------------------------------------------------
-----
# 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 = [
''file:/var/xen/default/test-default.dsk,hda1,w'',''file:/var/xen/default/t
est-swap.dsk,hda2,w'' ]
#-----------------------------------------------------------------------
-----
# Define frame buffer device.
#
# By default, no frame buffer device is configured.
#
# To create one using the SDL backend and sensible defaults:
#
# vfb = [ ''type=sdl'' ]
#
# This uses environment variables XAUTHORITY and DISPLAY. You
# can override that:
#
# vfb = [
''type=sdl,xauthority=/home/bozo/.Xauthority,display=:1'' ]
#
# To create one using the VNC backend and sensible defaults:
#
# vfb = [ ''type=vnc'' ]
#
# The backend listens on 127.0.0.1 port 5900+N by default, where N is
# the domain ID. You can override both address and N:
#
# vfb = [ ''type=vnc,vnclisten=127.0.0.1,vncdisplay=1'' ]
#
# Or you can bind the first unused port above 5900:
#
# vfb = [ ''type=vnc,vnclisten=0.0.0.0,vnunused=1'' ]
#
# You can override the password:
#
# vfb = [ ''type=vnc,vncpasswd=MYPASSWD'' ]
#
# Empty password disables authentication. Defaults to the vncpasswd
# configured in xend-config.sxp.
#-----------------------------------------------------------------------
-----
# 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= ).
# Define number of network cards
#nics=2
# Set if you want dhcp to allocate the IP address.
dhcp="off"
# Set netmask.
#netmask="255.255.255.0"
# Set default gateway.

# Set root device.
#root = "/dev/hda1 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"
#-----------------------------------------------------------------------
-----
# Configure the behaviour when a domain exits. There are three
''reasons''
# for a domain to stop: poweroff, reboot, and crash. For each of these
you
# may specify:
#
# "destroy", meaning that the domain is cleaned up as normal;
# "restart", meaning that a new domain is started in place of
the old
# one;
# "preserve", meaning that no clean-up is done until the
domain
is
# manually destroyed (using xm destroy, for
example); or
# "rename-restart", meaning that the old domain is not cleaned up,
but
is
# renamed and a new domain started in its place.
#
# The default is
#
# on_poweroff = ''destroy''
# on_reboot = ''restart''
# on_crash = ''restart''
#
# For backwards compatibility we also support the deprecated option
restart
#
# restart = ''onreboot'' means on_poweroff =
''destroy''
# on_reboot = ''restart''
# on_crash = ''destroy''
#
# restart = ''always'' means on_poweroff =
''restart''
# on_reboot = ''restart''
# on_crash = ''restart''
#
# restart = ''never'' means on_poweroff =
''destroy''
# on_reboot = ''destroy''
# on_crash = ''destroy''
on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''
#==========================================================================
Additionally, here is the listing of files the virtual machine is
intended to use:
$>find /var/xen -type f -exec ls -la {} \;
-rw-rw-rw- 1 root root 524288000 2008-02-26 14:20
/var/xen/default/test-swap.dsk
-rw-rw-rw- 1 root root 10737418240 2008-02-26 14:19
/var/xen/default/test-default.dsk
-rw-r--r-- 1 root root 5766 2008-02-26 15:04 /var/xen/guests/test-vm.cfg
I''m sure I''m missing a ton of configuration settings;
Essentially I
want to automate a VM install with a kickstart file (to which I don''t
even know were to reference it from at the moment)
I''m guessing the reference to the kick-start file will appear somewhere
in the config file? But ... back at square one.... I can''t even get a
VM to create itself... so I''ll start there first! :-)
My operating system is Fedora 8. Perhaps I should be focusing more on
using cobbler and koan, but at the present time I would like to know how
it''s done using the command lines.

See the comments in /etc/inittab. You might want to say extra = "5 xencons=tty", although it should default to 5. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
