[Xen-users] self-balloon driver AWOL

[James Dingwall <james-xen@xxxxxxxxxxxxxx>]

Hi,

I have been successfully using the self-balloon driver on my Ubuntu 
bionic systems in order to over-provision memory for lots of PV linux 
guests.  The workload works well for this strategy as typically a small 
number of guests require more memory for a short period and then they 
yield it again once they've done their work.  After upgrading to the 
latest HWE kernel based on Linux 5.3 this driver has been removed so the 
guests only start with the 'memory' value and do not increase to 
'maxmem' when required.  Is there a replacement driver which does this 
work?

Thanks,
James
