[Kimchi-devel] [PATCH 0/2] Live Migration UI v3

[Samuel Henrique De Oliveira Guimaraes]

Hi,

This is the output when I migrate a VM:

➜  ~ curl -k -u root  -H "Content-Type: application/json" -H "Accept: application/json" "https://localhost:8001/plugins/kimchi/vms/ubuntu-live/migrate" -X POST -d '{"remote_host":"10.10.71.37"}'
{
  "status":"running",
  "message":"starting a migration",
  "id":"4",
  "target_uri":"/vms/ubuntu-live/migrate"
}

The problem was that the data object was sending an empty username and password even if the input fields were empty, like this: {"remote_host":"10.10.71.37","user":"","password":""} . 

I fixed the JS and now it closes the modal window (which means the post request is being sent now) but it throws the following error:
"Unexpected exception: KCHVM0061E: Unable to create file /var/lib/libvirt/ubuntu-14.04.3-server-i386 (1).iso at 10.10.71.37 using user root."

I believe this is because I'm running out of memory and capacity on my server.

I did a quick fix in the form validation and in the JS and I'm sending a v4 now.

Thanks,
Samuel

The look of the dialog is exactly like I imagined. However I couldn't migrate using the dialog.

The button turns to 'Migrating...' and the dialog stood there for minutes until I gave up. Using the backend I can verify that the migration is possible using the same VM and host:

$ curl -k -u root  -H "Content-Type: application/json" -H "Accept: 
application/json" 
"https://localhost:8001/plugins/kimchi/vms/00-migrate-test/migrate" -X POST -d '{"remote_host":"a_valid_private_remote_host"}'

I advise to try to simulate the live migration test scenario to develop/test this feature.
You need two hosts running the same libvirt version. I believe you can do it with VMs with nested KVM enabled.



Let me know if you need any help,


Daniel
