Problems with live-migration

[Shadow]

Hey guys,

I have a strange problem when I try to make a live migration to another host.
The shared storage is a nfs server.

ERROR: migration aborted (duration 00:00:00): can't migrate VM which uses local devices
TASK ERROR: migration aborted

Here is my config:

args: -device AC97,addr=0x18
balloon: 1024
bootdisk: virtio0
cores: 4
cpu: core2duo
ide2: none,media=cdrom
memory: 3072
name: TestVM
net0: virtio=myMac ,bridge=vmbr0
ostype: win7
sockets: 1
usb0: spice
usb1: spice
usb2: spice
usb3: spice
usb4: spice
vga: qxl
virtio0: nfsserver01:100/vm-100-disk-1.qcow2,format=qcow2,size=80G

I don´t know why, if I remove

usb0: spice
usb1: spice
usb2: spice
usb3: spice
usb4: spice
args: -device AC97,addr=0x18

entries then I can migrate the VM to another host without problems.

Hope that you can help me.

Best regards

It should be enough to remove these:
usb0: spice
usb1: spice
usb2: spice
usb3: spice
usb4: spice

usbx is always a local resource.

Thanks for the quick response.

I use USB-Redirection to redirect usb devices to the VM.
What happens when I remove
usb0: spice
usb1: spice
usb2: spice
usb3: spice
usb4: spice
?
Do I have the chance to connect usb devices to the vm as usual?
I connect the usb device to the client, Remote-Viewer redirects it automatically to the vm?

Best regards

Hi mir,

maybe the questions was too simple.

I would be happy if you could answer me.

Thank you and best regards.

I guess this is a bug, because it should be possible to migrate such VMs. But I am unsure if that works with current spice version.

Thanks for the quick response.

I saw a live migration with usb controller several months ago (Fedora 18, Virt-Manager).
This worked perfectly.

Is there any solution for it (maybe some switch --force or something?)

Best regards

Try:

Thank you!

Can you explain how I can test it?

Maybe it is a very simple question, but I don´t know how to do...

Best regards

Can you explain how I can test it?

You need to wait until we release those packages then.

I found a tutorial which explains the most steps.
I try to compile it.

One important question:

The output is a deb file.
When I install it can I install the updates normally?
Will the updatescript (apt-get update && apt-get upgrade) replace my manual install of the deb file (if there is a newer and better version)?

Thanks again and best regards
