Hi,

I load the software from an .iso file in my Download directory.
I wonder what this means in detail.
The normal procedure with an .iso image file and a qemu VM is
to start qemu with the .iso file as -cdrom and the (empty) virtual
hard disk image file as -hda.
Then one would let the system that comes up from the .iso image
install its payload as bootable operating system on the virtual
hard disk.
If I run fdisk p on the Hard Disk I am using I get:
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 283117567 283115520 135G 83 Linux
/dev/sda2 283117568 312581807 29464240 14.1G 82 Linux swap / Solaris
Is this the view from the host operating system ?cfdisk /dev/sda
Did you submit /dev/sda to qemu as -hda ?
The drive is obviously marked as bootable.
As tomas already stated, this does not guarantee bootability.
Background:
The boot flag is a mark for generic MBR code which tells from where
to load a Volume Boot Record as next step of booting. One often can see
boot flag sensitive MBRs on freshly purchased USB sticks.
The usual boot loaders of Linux systems have other ways in their MBRs
to run the further boot stages up to the display of a boot menu.
Do you need more information?
What .iso image did you use ?
Can it be downloaded for free somewhere ?
What qemu command lines did you use and why ?
Did you do anything else as preparation outside qemu (and why) ?
What did you do when qemu was running ?
Have a nice day :)

Thank you all for your replies.
I am using Virtual Machine Manager 2.0.0 powered by libvirt to set up
the guest system. I burned a CD off of the .iso file and used it to
install the system. The installation went fine but reboot failed again.
I did detect an error that the 'v/lib/libvirt/images file was not
active. I had to create the images file and then run |"virsh pool-start
default" followed by "visrsh pool-autostart default". This fixed that
problem.

|The .iso file is caelinux2018.iso and is available free of charge at
caelinux.com. If you are not familiar with the package, it is a
compendium of scientific and engineering packages that - if your good
enough - could allow you to design and build your next airplane,
automobile, particle accelerator, etc. The CAE stands for Computer Aided
Engineering.|
|I think I have fix the major problem. More careful reading of the
installation instructions indicated that the installation is in two
parts. The loading of the disk image actually is a temporary install for
tryout. Dummy me overlooked the screen icon that said install to hard
disk. That fixed the boot problem. Now if I can figure out which hard
drive I am installed in I will be a happy camper.|
