Re: [Linux-cluster] Discovering the world of clustering



Hi,

I'm very sorry for I mistaked that this list is red hat internal list..
Links which I sent are unavailable from outside from redhat.com.

I'll show some tips when using xen from them.

- use 'w!' attribute for shared block device
ex. disk = [ 'tap:aio:/media/disk/VMImages/rhel5_1,xvda,w',
'tap:aio:/media/disk/VMImages/gfs_disk,xvdb,w!',]

- make a dummy network interface to build  virtual network,
 in /etc/xen/xend-config.sxp: 
  (network-script 'network-bridge bridge=xenbr0 netdev=dummy0')

- dnsmasq is very useful for constructing dns server for virtual
network.

regards,
