Re: dummy network interface laptop configuration problem

Hi,

Thanks for the script. It's working. But now I got a new problem. Whenever I try to create a new virtual machine using either virt-install or virt-manager I get this error:
Failed to get devices for domain rhel5pv1
libvirt.libvirtError: virDomainCreateLinux() failed

I guess I am doing something wrong in /etc/xen/xend-config.sxp. This is what I did in it:

(network-script 'network-bridge netdev=dummy0')

The line regarding xenbr0 is commented:

# The bridge is named xenbr0, by default.  To rename the bridge, use
#
# (network-script 'network-bridge bridge=xenbr0')

I guess this should bridge xenbr0 via dummy0.
Tell me if I am doing something wrong. One more thing I like to say is that the doc I pointed out earlier is not perfect. I wrote the script by my hand and then too it failed with the last 2 errors. Also the lines related on how to make xenbr0 bridge to dummy0 are not exact if you read them carefully.

Regards
Deependra

I suspect there's a formatting problem - when I tried to copy that script from the html page it came out a little strange.
Instead of ;; I got  . . on one line and , , on the next.

Without seeing your script it's hard to guess - but I'd take a careful look at the various quote marks and make sure that they are matched.
Here's the script I'm using - it works in a similar vein

You'll need to copy it into /etc/init.d and make sure that it's owned and readable and executable by root

chkconfig virt-network --add
chkconfig virt-network on
service virt-network start

Hello guys,

I am using Redhat Enterprise Linux 5 with Xen. Now I have a laptop on which RHEL5 is installed. I read the docs related to Xen on redhat's website where in the troubleshooting section they say to create a dummy0 network interface and bridge xenbr0 to dummy0 and finally NAT'ing  dummy0 so that it can access the public net.
Well I tried that article and I created a dummy0 interface as told in there and also bridged dummy0 to xenbr0 in /etc/xen/xend-config.sxp but I am getting problem in configuring NAT'ing (so that I can access the public network from within the virtual machine).
I am using the script given here:
https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-en-US/ch-virt-laptop-configurations.html

When I run the script I get these two errors:
./S99XenLaptopNAT: line 21: unexpected EOF while looking for matching `"'
./S99XenLaptopNAT: line 24: syntax error: unexpected end of file

Deependra
