gnt-instance migrate error (vif-ganeti)

Originally reported of Google Code with ID 1171.

Hello everybody,

What software version are you running? Please provide the output of "gnt-
cluster --version", "gnt-cluster version", and "hspace --version".

gnt-cluster (ganeti 2.15.2-1~bpo8+1) 2.15.2
hspace (ganeti) version 2.15.2-1~bpo8+1
compiled with ghc 7.6
running on linux x86_64

<b>What distribution are you using?</b>

Debian Jessie - Xen 4.4 (toolstack = xl)

<b>What steps will reproduce the problem?</b>
1.create instance
2.gnt-instance migrate "instance"

Failed with error (libxl not reading ready message.......)

In the file : /etc/xen/scripts/vif-ganeti (lig. 47):

domname=$(xm domname $domid)  => It should be 'xl' command 

and, this command return : instancename----incoming/0

so, at line 53:

source $NIC_DIR/$domname/$devid => issue an error in xen-hotplug (file not found)... because of the '---incoming' in the name of the file...

I think this is why the migration failed ? 

perhaps there is a workaround ? or a patch ? thank you for helping me, I am very new to ganeti and I don't want to break everything...

sorry for my english, I am french

best regards,
stephane ouvrard

Hi Stephane,
Thanks for reporting this bug. It is definitely an issue with xl support. We are using a different network setup however, so can't reproduce it. Patches are very welcome though.

domname=$(xm domname $domid)  => It should be 'xl' command -> No, it should be whatever the xen_cmd setting is for the cluster.

But right now it's hardcoded in the script, so it's borked.

xm is long obsolete (since Xen 4.1) and removed in Xen 4.5. It's time to switch everything to xl and drop the xen_cmd-related logic.
