Question

xen on centos node - ubuntu vm's network not reacheable

Asked by: allwebnow

I have xen 3.3.0 running on my main machine.  I've successfully gotten xen installed as well as a vps ubuntu installed and working.  I can only access it via vnc because the eth0 is giving some issues.  Let me know if anyone can figure out the correct configuration for this vm's setup.  Below is the .cfg file.  Neither of the vif's below worked correctly.  I'm so close to getting this vps up and this I think is the last step to getting it to work completely before I can install openqrm.

Thanks!

import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'
 
kernel = "/usr/lib/xen/boot/hvmloader"
 
builder='hvm'
 
memory = 512
name = "openqrm"
vcpus=1
acpi=1
apic=1
vif = [ 'type=ioemu, bridge=peth0' ]
#vif = [ 'type=ioemu, bridge=xenbr0' ]
 
 
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
 
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
 
#Comment this line after OS install
disk = [ 'file:/var/lib/xen/images/openqrm.img,hda,w' , 
'file:/root/ubuntu-9.04-server-amd64.iso,hdc:cdrom,r' ]
 
 
boot="c" #MAKE THIS c INSTEAD OF d AFTER OS LOAD
serial = "pty" #Uncommented AFTER OS LOAD
bootloader="/usr/bin/pygrub" #Uncommented AFTER OS LOAD

Ok, i found out that xenbr0 is not listed in the "brctl show" list.  How would i be able to get xenbr0 listed?  This is supposedly the only way to get xen vps network' to work on a centos dom0 machine.  Any insight would be very helpful.  Let me know.  

 

by: mwecomputersPosted on 2009-11-05 at 07:25:39ID: 25750431

Please cut/paste the output of running this command: '/etc/xen/scripts/network-bridge status'

 

by: allwebnowPosted on 2009-11-05 at 07:29:51ID: 25750481

We've figured this out.  For Centos host dom0, you need to change SELINUX=enforced to SELINUX=passive

 

by: allwebnowPosted on 2009-11-05 at 07:30:18ID: 25750488

I'm sorry...
I meant SELINUX=permissive
