Re: [libvirt] how to change the boot order of a qemu-kvm guest os



Thanks .
What exactly is the option about storage pools in virt-manager for the local host qemu. is this by any chance a method to create common storage which i may use for a clustered File System . I hope I am not asking the wrong set of questions with respect to the context of this mailing list .

Thanks and Regards

   Hi
        I am using libvirt and virt-manager to manage and run 2 Fedora 10
   guest operating systems for the sake of installing a Oracle RAC
   environment . As part of the process after using the both gues for some
   work i felt the nedd to add an additional virtual scsi disk to one of the
   hosts.
   Trying to start the guest os after adding this scsi virtual disk to the
   host fails (see image)  . The guest BIOS screen and all comes up fine but
   it now seems to be trying to boot from the newly added disk . Fiddling
   around with the order of the disks as listed in the xml has not helped
   either .

Yeah this is a bug in libvirt - its stupidly reordering disks itself.
I've got a patch that will be in the next libvirt release

There's no real workaround before that other than make sure you only
use the same type of disk - eg always SCSI, or always VirtIO, but
never a mix of both.
