Firstly,thanks for your continuously help. I am not sure how to enter a local ISO path into the install URL field in the installation method "Network install(HTTP,FTP or NFS)" url to disk. I have tried to set up a http server in the s390x ,but find that the "localhost" is x86 which running virt-manager. Also , I try the <a class="moz-txt-link-rfc2396E" href="file:///var/lib/libvirt/images/**.iso">"file:///var/lib/libvirt/images/**.iso"</a>, it don't find the iso image. So if you can provide some examples of "local iso host" ,it will be really better. Big Thanks~ Best Regards, Kevin <div class="moz-cite-prefix">On 2015年11月12日 04:05, Cole Robinson wrote: </div> <blockquote cite="mid:56439F9C.9090200@redhat.com" type="cite"> <pre wrap="">On 11/11/2015 12:45 AM, Kevin Zhao wrote: </pre> <blockquote type="cite"> <pre wrap="">Hi Cole & all, There is a question just confusing me. When I use virt-install , set the --location parameter like this : --location /tmp/**.iso, virt-install can search the iso and get the tree.info , kernel.img and initrd.img. But when I replace the parameter "--location " with the "--cdrom", it will not be able to search the iso for kernel.img and initrd.img ,I need to specify the kernel and initrd(Maybe inn the arch ppc64le and s390x). But when I use virt-manager, choose the cdrom I can not get the functions just like "--location". So does the virt-manager support the functions just like "--location" do? I see that by using network installation , virt-manager will search for tree.info, how to use it to get a local iso treeinfo? My descriptions may not be very clear . So feel free to let me know if you have any question. </pre> </blockquote> <pre wrap=""> The difference between --location $ISO and --cdrom $ISO are kinda subtle: --cdrom $ISO just passes the $ISO as a cdrom device to the guest --location $ISO tries to mount the $ISO locally, and treat that local path like a --location $URL install, pulling out the kernel/initrd. This allows passing in custom kernel args, but is kinda limited since you need root access to mount the iso You can actually trigger this with virt-manager by entering a local ISO path into the install URL field - Cole </pre> </blockquote> </body> </html>
