Subject: [PATCH] tools/libxl: modify static-max in xenstore when setting maxmem
Date: Wed, 18 Jan 2017 19:25:57 +0100	[thread overview]
Message-ID: <20170118182557.11979-1-jgross@suse.com> (raw)

xl mem-max is setting the hypervisor memory limit of a domain, but not
the memory/static-max value in Xenstore. This prohibits setting the
memory size above the old maximum size.

Set the new maximum value in Xenstore.
