RE: [Xen-users] RE: XCP 0.5 - dom0 vcpus/RAM settings not working

["Joe Linoff" <jlinoff@xxxxxxxxxx>]

Hi Jon:

I also noticed /etc/init.d/set-memory-target which seems to reset the
memory based on configuration parameters and installed repos
(/etc/xensource/installed-repos). 

Cheers,

Joe

Hi Jon:

Thank you. This is excellent information. 

> XCP has an init script that unplugs all but 1 VCPU. Look in the script
/etc/init.d/unplug-vcpus.

Do you know whether I can I disable that init script in a clean way? 

> Also, xapi will balloon dom0 using a formula ...

Great. I am looking at it now.

Regards,

Joe

Hi Joe,

XCP has an init script that unplugs all but 1 VCPU. Look in the script
/etc/init.d/unplug-vcpus. 

Also, xapi will balloon dom0 using a formula based on the amount of
physical ram in your machine. Have a look at
http://support.citrix.com/article/CTX124259 -the procedure for XCP
should be roughly similar.

Hope this helps.

Jon
