[Xen-users] a question about multiple VMs share one file system
Hello, I have multiple VMs running in a cluster and migration is required. I have set them up by NFS and each VM has an independent file system(each one is a directory) on the NFS server. My question is, is it possible to let all VMs share one file system? How can I do that? If I change the privilidge to read-only, how does each VM write into their file system? Thanks for any help. cmfs _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
