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

[George Shuklin <george.shuklin@xxxxxxxxx>]

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.
