I still think /proc/xen/balloon makes it far too easy to shoot yourself in the foot, even for the non-casual user. Simply forgetting to leave the units off the end of an echo can bring your domain (even dom0) to a screeching halt. Such as doing: echo 200000 > /proc/xen/balloon instead of: echo 200000K > /proc/xen/balloon. I know that it's really difficult to determine how low is too low. Could I recommend a small interface change though, that would force the user to always specify units {B,K,M,...}? That might help a little at least. --=20 Thanks, Paul Larson plars@linuxtestproject.org http://www.linuxtestproject.org --=-/eHewpjEJ+Otr/QeXijn Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBC29D7bkpggQiFDqcRAusEAJ9qn63y8eMZL+a6B5d89Wc502TDtgCgjU+N hjaQ1Wrw5YvGm7ZhSztv8Ic= =uBqN -----END PGP SIGNATURE----- --=-/eHewpjEJ+Otr/QeXijn-- --===============1497814995== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel --===============1497814995==--
