hello everyone: I installed xen-4.2-unstable with kernel 2.6.32.40 on centos-5.5(x86_64) successfully. I boot a windows server2003 domU(HVM) named win2003,and use the command "remus win2003",and the remus functions properly. But when i boot a centos/rhel domU(i386/x86_64,HVM)and then use the remus, it fails and returns " Disk is not replicated: file:/home/xen/tpl/hvm/centos_386.img,hda,w Disk is not replicated: file:/home/xen/tpl/hvm/CentOS-5.5-i386-bin-DVD.iso,hdc:cdrom,r Segmentation fault ". the configure file is as follows: kernel = "hvmloader" builder=''hvm'' memory = 1024 name = "rhel" vcpus=4 pae = 1 acpi = 1 apic = 1 disk = [ ''file:/home/xen/tpl/hvm/rhel.img,hda,w'', ''file:/home/xen/tpl/hvm/rhel-server-5.4-i386-dvd.iso,hdc:cdrom,r'' ] device_model = ''qemu-dm'' boot="cd" sdl = 0 vnc = 1 vnclisten = "0.0.0.0" stdvga = 0 serial = "pty" Did anybody know the reasons and give me some detail information? I would really pleasure if you could give some advices, thanks lot! yours yunjie du _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
