Set Static Memory for VM in XOA

KPS

Hi!

I am quite confused about the way XOA is showing the memory settings of a VM.

In Xencenter, there was:

Static --> set fixed value
OR
Dynamic - min/max

XOA is always showing both - static AND dymamic without the option to choose.

Can you give me a hint on how to understand it?

Thank you and best wishes

It's the same thing presented differently. Click on the amount to change the value.

Yes, but what is the equivalent of "static"?
I have to setup 4 values and I do not understand why?

For me, there are just two options:

static with ONE value
dynamic with TWO values

Sorry, but I do not understand it, yet.

Because you are kind of fooled by XenCenter UI. Static only means dyn min == dyn max == static max. In your screenshot, you are already in static memory.

Definitely biased through Xencenter and vCenter, but:

Why are there 4 settings?
Why 2 settings for „static“? Isn’t the characteristic oh static, that it is one fixed value?

olivierlambert

Static memory definition in Xen means that dynamic min, max and static max are equal.

Check the VM params with xe, you will never see any "static memory" field. The UI of XenCenter is just providing a "helper", but clicking on static will just set dynamic min, max and static max to the same value.

Thank you!
But what is the meaning of „static min“?

@KPS That is the minimum memory limit as defined by the related template.

Yes, you can ignore static min, 99% of the time it's not relevant.
