Hyper-V 2012 R2 and SLES

First off not sure if this is the correct forum or not but I thought I would take a shot, if someone knows where this might need to be posted instead please by all means let me know,

The question I have been asked has to do with the following,

"With Windows Hyper-V 2012 R2 there is support for Linux and Dynamic Memory. I’m wondering if a) Novell supports dynamic memory and b) If so, what versions?

I am starting to do some testing in the area and want to make sure."

Would anyone be able to provide some details?

Thank you,

I’d say this was the correct forum - you’re asking about virtualised
SLES (albeit virtualised on Hyper-V).

http://technet.microsoft.com/en-us/library/hh831766.aspx would seem to
cover it - under “Guest operating systems that support Dynamic Memory”
it lists

–begin–
SUSE Linux Enterprise Server 11 SP3

Integration services are built-in and do not require a separate download
and installation.

Important: On Hyper-V in Windows Server 2012 virtual machine Dynamic
Memory RAM settings must in multiples of 128 MB.
—end—

There’s also the following note under section 12.5 Hyper-V of the SLES11
SP3 release notes[1]

–begin–
12.5.4 Hyper-V: Memory Ballooning Support

Windows hosts dynamically manage the guest memory allocation via a
combination memory hot add and ballooning. Memory hot add is used to
grow the guest memory upto the maximum memory that can be allocated to
the guest. Ballooning is used to both shrink as well as expand up to the
max memory.

HTH.
