[Xen-users] XEN : Is there any way for sharing base virtual imgae.
Hello Requirement : I want to create a base image having ro filesystems and share the same virtual image between all domU''s. ? I found some way to doing it using UNIONFS and AUFS , but did;nt find any proper document as such, And adding to that , can anyboody help me out it creating COW filesystems. ? Thanks in advance. -- Regards Arun Sharma 0-934-829-3810 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Take a look at GFS file system. It''s made for "concurrent" access to the same file system. I already read a few reports about people using it for sharing a single domU image between several instances. Maybe you should take a look at: http://people.redhat.com/pcaulfie/docs/xencluster.html Cheers Reto Gantenbein Arun Sharma wrote:> Hello > > Requirement : I want to create a base image having ro filesystems and > share the same virtual image between all domU''s. ? > > I found some way to doing it using UNIONFS and AUFS , but did;nt find > any proper document as such, > > And adding to that , can anyboody help me out it creating COW filesystems. ? > > Thanks in advance. > > -- > > > Regards > Arun Sharma > 0-934-829-3810_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
