[Xen-users] Re: Re: I have no xenbr0 and peth0 with bridge-utils package

Fajar,

 

Thanks for your proposal.

because I plan to make some development in the xen source codes,I cannot use distro-bundled Xen and have to compile them by myself.

I  install xen on CentOS 6.0 .When i try to set up xend ,there is something wrong happening.The following is about the outcome of some commands(including "brctl show")just after opening the gnome-terminal.

 

[root@localhost ~]# brctl show
bridge name bridge id  STP enabled interfaces
[root@localhost ~]# service xencommons start
Starting xenstored...
Setting domain 0 name...
Starting xenconsoled...
[root@localhost ~]# service xend start
RTNETLINK answers: Device or resource busy
[root@localhost ~]# service xendomains start
[root@localhost ~]# brctl show
bridge name bridge id  STP enabled interfaces
tmpbridge  8000.000000000000 no  
[root@localhost ~]#

 

I can do nothing about this and this problem have influence on vms' creation.Help please.

Short answer: don't bother. Just use distro-bundled Xen, and if
there's a problem people using the same distro can help you.

Long answer:
Newer version of Xen won't have xenbr0. This is normal. The bridge
will be eth0 (or whatever your primary network device is). What is the
output of "brctl show"?

Also, the current recommended way to setup bridge is to use your
distro's mechanism (e.g. /etc/network/interfaces,
/etc/sysconfig/network-scripts/*), so you shouldn't use network-bridge
script.
