I tried installing a xen disk image to glusterfs : version 3.0.4. Transport tcp (Gbit). Glusterfs works fine with other applications. Iozone reports 110Mbytes/s read / write. I copied and existing xen disk image to glusterfs as root. [root at xenbox xen]# ls /data1/vm/xen/SL54/sl54.img /data1/vm/xen/SL54/sl54.img [root at xenbox xen]# xm create -c sl54.data1 Using config file "./sl54.data1". Hangs at the booting stage. If I copy the sl54.img to local disk, then vm boots ok. Also noted if I use RedHat virt-manager to kickstart a new vm, network dies at loading xenblck driver when the image directory is on glusterfs. I know xen does some wierd network things. Perhaps some resource conflicts ? Nick This e-mail message may contain confidential and/or privileged information.
