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
http://www.redhat.com/archives/libvir-list/2009-August/msg00340.html
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.
