[Xen-devel] RE: How to simply automatically resume suspended Xend managed domains on Xend start in Xen 3.2.1

["Artur Linhart - Linux communication" <AL.LINUX@xxxxxxxxxxx>]

Hello,

 

            I have looked into the XendDomain.py and there in the method „autostart_domains“ is really no handling of the automatical resume of the xen domains, which have been suspended on xend stop. Is there any other way how to simply make it? I think, this would be a usefull feature to have it, if the „on_xend_end“ already supports the „suspend“ option. It looks the implementation of such a function could be relatively easy...

 

            With best regards

 

                        Artur

Subject: How to simply automaticall resume suspended Xend managed domains on Xend start in Xen 3.2.1

 

Hello,

 

            I try to configure the automatic suspension of some domains by the end of Xend (especially older hvm domains with windows which cannot react on the shutdown signal). If I write into the domain configuration file the lines

 

if works well with the linux domains, the domain is shut down on xend stop and started with xend start.

 

Also if specifying

 

works well now (the snapshot did not work till I did not applied the patch mentioned in
http://xen.markmail.org/search/?q=xend+suspend+problems#query:xend%20suspend%20problems+page:1+mid:6bnxrk4eoonnyuyy+state:results
- before the snapshot has not been created correctly) – the memory snapshot is created in some instance’s subdirectory of the directory /var/lib/xend/domains after xend is stopped like by explicite call of xm suspend command.

 

Is there any way how to resume such a suspended domain on xend start?

If specifying

then the domain is not resumed, I have tried also

(resume is not documented if starting xm create --help_config, but I have tried it) – but also without success... is there some way how to bring xend to the resume of the suspended domains automatically, or do I have to write my own scripts for it?

 

With regards,
