Enhancement: Allow ability to modify DOM0 memory allocation

[agador]

Context

xo-web 5.9.1

Expected behavior

Add ability to modify the DOM0 memory allocations and suggest REBOOT (since it is required to have the changed value take effect).

Current behavior

Not currently available in XO nor in XenCenter, except for XS-7.1

The function can be performed via the CLI on any version of XS. The ability to use XC to modify the values is only available on XS-7.1

I suppose the XenAPI only expose this since 7.1

There is probably no other way than using CLI for previous versions.

[agador]

That was my impression as well. I wasn't sure if you wanted to do some "XOA" magic or not. If you want to make it a 7.1+ feature so you my use the API, I'm good with that.

[olivierlambert]

I think there is no reasonable magic to do it, so we'll probably display the option if it's a 7.1 or more recent 👍

Hi, when will this feature be available in XO?

[olivierlambert]

Hi,

Likely when we have more bandwidth and/or when a paid custom will raise the priority :) So I can't really tell now.

The implementation should be straightforward: simply exposing the ability to set the VM of the host's control domain.

If it does not work, we should use xapi-inspector between XCP-ng Center and the XAPI.
