[Xen-devel] question when xm create the ubuntu virtual machine in RHEL5
Everyone:
Hello. i want to setup the ubuntu virtual machine in the RHEL5 OS,
and i have install the package of xen and xen-libs from the origine package
in the RHEL5 ISO.xen-3.0.3-25.el5.x86_64.rpm and
xen-libs-3.0.3-25.el5.x86_64.rpm because i use the AMD 3800+ platform . I
follow the instruction copy the /etc/xen/xmexample.hvm as /etc/xen/ubuntu2
the content of this is like this
#===========================================================================#
Python configuration setup for ''xm create''.
# This script sets the parameters used when a domain is created using
''xm
create''.
# You use a separate script for each domain you want to create, or
# you can set the parameters for the domain on the xm command line.
#===========================================================================
import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
arch_libdir = ''lib64''
else:
arch_libdir = ''lib''
#----------------------------------------------------------------------------
# Kernel image file.
kernel = "/usr/lib/xen/boot/hvmloader"
# The domain build function. HVM domain uses ''hvm''.
builder=''hvm''
memory = 128
# Shadow pagetable memory for the domain, in MB.
# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
shadow_memory = 8
# A name for your domain. All domains must have different names.
name = "ExampleHVMDomain"
# 128-bit UUID for the domain. The default behavior is to generate a new
UUID
# on each call to ''xm create''.
#uuid = "06ed00fe-1162-4fc4-b5d8-11993ee4a8b9"
#-----------------------------------------------------------------------------

#cpus = "" # leave to Xen to pick

# Optionally define mac and/or bridge for the network interfaces.

#vif = [ ''type=ioemu, mac=00:16:3e:00:00:11, bridge=xenbr0,
model=ne2k_pci''
]
# type=ioemu specify the NIC is an ioemu device not netfront
vif = [ ''type=ioemu, 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:hda1,hda1,r'' ]
disk = [ ''file:/var/images/min-el3-i386.img,hda,w'',
'',hdc:cdrom,r'' ]
#----------------------------------------------------------------------------
# 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''

#----------------------------------------------------------------------------

stdvga=0
#-----------------------------------------------------------------------------
# serial port re-direct to pty deivce, /dev/pts/n
# then xm console or minicom can connect
serial=''pty''
#-----------------------------------------------------------------------------
# enable sound card support, [sb16|es1370|all|..,..], default none

# absolute mouse)
#usbdevice=''mouse''
#usbdevice=''tablet''
#-----------------------------------------------------------------------------
# Set keyboard layout, default is en-us keyboard.
#keymap=''ja''
in the red word is i have modified ,these are
boot="cda" => boot="dca"
sdl=0 => sdl=1
vnc=1 => vnc=0
and no more has been modified .
but when i use command
xm create ubuntu2
it fails with the notion of
Using config file "/etc/xen/ubuntu2".
Error: Disk image does not exist: /var/images/min-el3-i386.img
i make sure /etc/xen/ubuntu2 is the config file i edit
and the /var/images/min-el3-i386.img exists when i use command
dd if=/dev/zero of=/var/images/min-el3-i386.img bs=1M count=128
to make it
i google the website to figure out this problem . As a result , i notice
that some said just because the
selinux not allow the file access ,and i add the command
semanage fcontext -a -f "" -t xen_image_t
''/var/images(/.*)?''
and making sure the rule is in the context as i type command
semanage fcontext -l | grep xen_image
/var/images(/.*)? all files
system_u:object_r:xen_image_t:s0
this resolution does not work .
can someone tell me how to solve this problem when i create the xen vm.
thank you
regards
jeppeter

That would tell you if it''s Selinux that is the problem or not. -- Mats> > thank you > > > > regards > > jeppeter > > > > > > >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
