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

Hm... Strange, I already done with migration of VM from slave (0.5) to master (1.0).

Actually, I do a lot of tests before, so this script may be no completed.

Guess #1: actually, I don't use guest tools for linux (it's kinda strange for PV kernels...), so try to disable guest tools and run this script again.
Guess #2: I put a higher versions during my tests. So use 99 instead '1' and '3' (and something like 99999 for Build Version).

And you can see state of guest tools by 'xe vm-list params=PV-drivers-up-to-date,PV-drivers-version', it must shows 'true for up-to-date'.

Dear all,

 

I patched the script with xe support:

 

#################################################################

#!/bin/sh

domlist=`xe vm-list params=dom-id power-state=running|tail -n +2|awk '{print $5}'`

 

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

        echo $dom

done

#################################################################

 

After executing it does not still work:

 

[root@xcp1 ~]# xe vm-migrate vm=Ipazia host=xcp2 live=true

You attempted an operation on a VM which requires a more recent version of the PV drivers. Please upgrade your PV driver

s.

vm: 439e2d7a-f22d-2265-d1c8-ae38c7445438 (Ipazia)

major: 1

minor: 3

<extra>: 3

 

Any idea?

 

Thanks and 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.
