12:53 p.m.
I can explain the cause :)
when disk is first device, and the iso is unreachable the vm should not
start (you can try it... create a new vm, give it an iso -> deactivate
the iso domain -> try to start the vm -> you will get an error in UI).
the vm configuration's boot sequence is a set one. it will not change if
you eject the cd... so next time you try to run the vm it will still try
to boot from the disk you ejected.
when you ran the vm, there is an xml file sent to libvirt and that is
the vm configuration. even if you ejected the cd, the boot sequence in
the xml still has the cd as first boot device. hence, when we try to
re-create the vm in the target host, we will try to create the vm with
the cd as first device -> it does not exists anymore -> we get an
exception and fail migration.

Ok, so I shut down VM, unchecked Attach CD, powered on VM and now
migration succeeded. Go figure.
Thanks everyone for your help! I still dont know what is the cause of
this issue, but at least I know how to fix it.

Hi again
I tried to reproduce this issue and unfortunately

So there must be something else, but I cannot
figure out what
is wrong, because it is happening only with some VMs.
Nonetheless I attached new log files to investigate.

Hi
Thanks for your help. I will
provide all log
files a
little bit later,
but so far I have noticed some
pattern when
migration
fails. Those
particular VMs, which fails to
migrate, were
installed
from ISO image,
usual installation. So, I believe
you can
reproduce
the issue by this:
1. Upload ISO image to ISO domain
2. Install new OS by booting from
ISO image
and check
Attach CD in Boot
Options
3. Delete ISO image from ISO domain
4. Try to migrate VM to another host.
I have not tried this yet, but I
have noticed that
only those VMs fails
which had been install from ISO
image which is
not in
ISO domain
anymore. I have also VMs created from
templates and
those VMs I can
migrate just fine.
did you stop the VMs post install? did
you try to
start
them without the iso attached?
otherwise, you can't start them, as
there is a
missing iso
for the target qemu process
Indeed. That is a known libvirt/qemu issue
that even
though
the CD is defined as optional and VM can
be started
without it
on original host, it fails upon migration when
destination is
being created.
Thanks,
michal
I will provide more log files later.
