XenforCentOS6...need help to setup a PCI passthrough network

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

 

I have used this

http://wiki.centos.org/HowTos/Xen/Xen4QuickStart

and everything works like a charm then I installed a VM using

http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt

only to realize later that I don't want NAT.

I would want to use PCI passthrough and so i used

virsh net-destroy default

virsh net-undefine default

and

net-create /home/kartik/passthrough.xml

net-autostart passthrough

net-start passthrough

here is the output of /etc/libvirt/qemu/networks/passthrough.xml

 

<!--

or other application using the libvirt API.

<network>

  <name>passthrough</name>

  <uuid>d947fa14-af51-c615-279c-5d56ced04e44</uuid>

  <forward mode='hostdev' managed='yes'>

    <pf dev='eth0'/>

  </forward>

</network>

 

 

Is my approach right? After this I tried to restart using s

shutdown –r now( but the machine is not rebooting)

 

Welcome to virsh, the virtualization interactive terminal.

 

Type:  'help' for help with commands

       'quit' to quit

 

virsh #

virsh #

virsh # list --all

error: Failed to reconnect to the hypervisor

error: no valid connection

error: unable to connect to 'localhost:8000': Connection refused

 

Can anyone help?

 

Regards

kartik
