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

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

domlist=`xl list|tail -n +2|awk '{print $2}'`
for dom in $domlist;
        xenstore-write /local/domain/$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
        xenstore-write /local/domain/$dom/data/updated 1

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


[debug|Logging xapi version info D:4634c2be5fc0|xapi] Server
[debug|Logging xapi version info D:4634c2be5fc0|xapi] product_version:

[debug|Logging xapi version info D:4634c2be5fc0|xapi] License
filename: /etc/xensource/license

the version 1.3 is a source of problems.
