Re: [Xen-API] XCP 1.6 - XenMotion and VM replication

In the next xcp update can the basic output from 'xe help' be updated to include drtask-* commands?

Hi George,

xenserver 6.1

[root@xen-xs6 ~]# xe dr[tab]
drtask-create       drtask-destroy      drtask-list drtask-param-get    drtask-param-list

xcp 1.6

[root@xen-xcp16 ~]# xe dr[tab]
drtask-create       drtask-destroy      drtask-list drtask-param-get    drtask-param-list

Yes seems the same drtask commands exists on both xcp and xs 6.1.
Althought I don't get yet how it can be used to acheive what I'm trying do to. I'll investigate :)

[root@xen-xcp16~]# xe help drtask-create
command name            : drtask-create
        reqd params     : type
        optional params : device-config:, sr-whitelist
        description     : Create a disaster recovery task.

Thanks for your answer :)

Cheers,
Sébastien

I'm not sure but new set of commands 'dr-something' seems be those.

Again, not sure if those are enabled in XCP.

Hi list,

Congrats again to the team for the XCP 1.6 release!

I was asking myself if it was possible somehow, using two XCP 1.6 with local storage and the new "share nothing" live migration features, to periodically clone running VMs from the first server to the second server.

Not really a live migration but something like snapshotting a running VMs on server1, cloning it to server 2 but leaving it not running. Like for example every 5 minutes.

So in case server1 goes wrong (hardware problems or so on), you can start a 5 minutes or less clone of the VM on the secondary server.

Sorry for my bad english, hope my question is clear :)

Cheers,
Sébastien
