[Xen-devel] Error migrating VM to secondary host using COLO replication

[Sadi <sadijrp@xxxxxxxxx>]

Hello,

I've been trying to set COLO replication to work but i'm stuck on a problem when migrating de primary VM to secondary host.

I have been following the instructions from this wiki

- http://wiki.xenproject.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping

and this mail thread

 - http://xen.markmail.org/search/?q=COLO#query:COLO+page:1+mid:fb7wrn62vbks4unn+state:results

I'm anexing the steps i took setting the environment before facing this problem when executing 'xl remus' command:

>migration target: Ready to receive domain.

>Saving to migration stream new xl format (info 0x3/0x0/2840)

>Loading new save file <incoming migration stream> (new xl fmt info 0x3/0x0/2840)

>Savefile contains xl domain config in JSON format

>Parsing config from <saved>

>xc: info: Saving domain 2, type x86 HVM

>xc: info: Found x86 HVM domain from Xen 4.7

>xc: info: Restoring domain

>xc: Frames iteration 0 of 5: 1045504/1045504  100%

>xc: Domain now suspended: 0/0    0%

>libxl: error: libxl_qmp.c:702:libxl__qmp_initialize: Connection error: No such file or directory

>libxl: error: libxl_colo_restore.c:817:colo_restore_setup_cds_done: COLO: failed to setup device >for guest with domid 1

>xc: error: Restore failed (38 = Function not implemented): Internal error

>libxl: info: libxl_colo_restore.c:320:libxl__colo_restore_teardown: colo fails

>libxl: error: libxl_stream_read.c:852:libxl__xc_domain_restore_done: restoring domain: Function >not implemented

>libxl: info: libxl_colo_restore.c:320:libxl__colo_restore_teardown: colo fails

I'm hoping that someone could provide with directions.
