R: [Xen-API] XCP - live migration trouble [SOLUTION]

[<cluster@xxxxxxxx>]

Hi all,

First of all thanks George!

I think that this is a very big trouble, am I the only one that experimented it?

Is there a plan to release a new version of XCP without this bug? 

What about Windows VMs?

Regards,
FG

Good day, everyone.

How to solve

1) I don't know what happens to HVM (include windows).
2) This works with PV linux

3) Upgrade master (I you have interest in this you are already done this).

4) Run on every slave to be evacuated following script:

--------------
#!/bin/sh
domlist=`xl list|tail -n +2|awk '{print $2}'` for dom in $domlist; do
        xenstore-write /local/domain/$dom/attr/PVAddons/MajorVersion "1"
        xenstore-write /local/domain/$dom/attr/PVAddons/MinorVersion "3"
        xenstore-write /local/domain/$dom/attr/PVAddons/MicroVersion "3"
        xenstore-write /local/domain/$dom/attr/PVAddons/Installed "1"
        xenstore-write /local/domain/$dom/attr/PVAddons/BuildVersion
"42052"
        xenstore-write /local/domain/$dom/data/updated 1 done
-----------------

5) Do evacuation.
...
6) PROFIT???

I think I found source of problem:

guest tools declare version major=1, minor=0, but XCP 1.0 expect to have
1.3:

xensource.log

the version 1.3 is a source of problems.
