[Qemu-devel] Migration from older Qemu to Qemu 2.0.0 does not work

[Qemu-devel] Migration from older Qemu to Qemu 2.0.0 does not work

[Stefan Priebe - Profihost AG]

Hello list,

i was trying to migrate older Qemu (1.5 and 1.7.2) to a machine running
Qemu 2.0.

I started the target machine with:

-machine type=pc-i440fx-1.5 / -machine type=pc-i440fx-1.7

But the migration simply fails. Migrating Qemu 2.0 to Qemu 2.0 succeeds.

I see no output at the monitor of Qemu 2.0.

# migrate -d tcp:a.b.c.d:6000

# info migrate
capabilities: xbzrle: off x-rdma-pin-all: off auto-converge: on
zero-blocks: off
Migration status: failed
total time: 0 milliseconds

The target machine is still running at this point with no output.

Stefan

I'd expect you to have to run with the same machine type on both sides.
I ran some simple virt-test migrate tests (just the basic one) and got
v1.5.3->v1.6.2
v1.5.3->v1.7.1
v1.5.3->v2.0.0-rc1
   working for most machine types, pc-i440fx-1.5 passed with all of those.
Note that's only the simplest test.

My test involved USB Controller virtio Network cards and rbd virtio-scsi drives.

Can you give me your simple start line so I could test if this works for me while adding some more arguments.

Thanks!

That probably makes things more interesting :-) I'd start with the simplest
config you can find and add each one of those until it breaks.

I've got a slightly hacked up libvirt, but I'm doing

  ./run -t qemu --machine-type=$MACTYPE -g Linux.JeOS.19.x86_64.i440fx --qemu-bin=$SRC --qemu-dst-bin=$DST --qemu_sandbox=off --tests migrate.default.tcp --disk-bus=ide

and looking at the logs we have:

Anything on its stdout?

Another test you could do, in addition to changing the devices, is this:

1) try with commit 6141f3bd6904df7cf9519c6444a14a608b9874c4 on the 
destination (the next one caused a migration problem that was fixed 
later).  If it passes, go to step 1a.  If it fails, go to step 2.

1a) try with commit c01a71c1a56fa27f43449ff59e5d03b2483658a2.  If it 
passes, go to step 1b.  If it fails, report it here.

1b) bisect between v2.0.0 (known-bad) and 
c01a71c1a56fa27f43449ff59e5d03b2483658a2 (known-good) to find the 
culprit.  Report results.

2) change the source to v1.7.0 and bisect between v1.7.0 and 
6141f3bd6904df7cf9519c6444a14a608b9874c4.  Report results.

Thanks!

OK biggest bummer it works fine with all freshly started VMs. No idea why.

So i'll try with paolos idea migrating old VMs.

Sadly no.

But far more complex than i thought. I'm seeing this problem only on 
machines originally started under qemu 1.5 ten migrated to qemu 1.7 with 
machine type=pc440fc-1.5 . Only those do not work. But they also do not 
work migrating them to qemu 1.7.1.

So let's ignore the whole fact and thanks for your bisect ideas. I will 
just shut them down all and start them with a fresh qemu 2.0.

Hi,

i now was able to catch the error.

It is:
Length mismatch: 0000:00:12.0/virtio-net-pci.rom: 40000 in != 10000
qemu: warning: error while loading state for instance 0x0 of device 'ram'

This is a bug of your distribution.  The file sizes for ROMs should 
never change.  In particular, if you round the sizes up to the next 
power of 2 you should always have:

128k for bios.bin
256k for bios-256k.bin
64k for pxe-*.rom
256k for efi-*.rom
64k for vgabios-*

Unfortunately, most distribution get pxe-*.rom sizes wrong, because at 
some point iPXE grew more features and didn't fit in 64k anymore with 
the default configuration.  I know at least Fedora does.

The solution is to copy the binaries from the QEMU git repository 
(directory pc-bios/) to /usr/share/qemu.

Hi,

i compile qemu on my own.

I have the rom files under /usr/share/kvm and they look like this:

What about the source machine?
