Re: [Xen-users] mem-set

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

You have to also specify mem=1024M on the guest's kernel command line, eg. by 
adding it to the extra= parameter in the config file.

You need to do this because otherwise the guest does not know how large a 
memory to expect - it needs to know this so that it can size its data 
structures correctly.  If you set this to the largest you expect the domain 
to grow then you'll be able to grow as well as shrink the domain.

This won't work for HVM domains, which can't (as far as I know) be grown 
beyond their initial allocation.

Cheers,
mark
