From: "Michal Kopacki" <mkopacki(a)gmail.com&gt; To: users(a)ovirt.org Sent: Wednesday, March 21, 2012 3:59:00 AM Subject: [Users] disable ballooning mode I'm trying to get virtual windows and specific software on it working. Windows is working fine but i'm getting blue screen when trying to start this particular application (which works fine in vmware). I figureout that there could be some kind of problem with memory.

My question is about ballonning memory: is it on as default ? If yes, then how to disable it ? Did anyone also discovered such problemes ? -- Michal _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I'm clueless to be honest. First thing I've done was convert machine from virtualbox and start on ovirt - windows is ok, application is not. Second i made new windows installation and install mentioned app - bluescreen again. -- Michal

Mentioned application is a software for switching voip calls. There is a bunch of helper appliactions (which are working fine), problem is with main application server/deamon. It is develop internaly by company I work for. We use this applications on many physical and wirtual servers (including kvm and xen on different hosting providers) and never see such behave as on ovirt.

Yes, I'm aware of that. It's the reason I choose ovirt. > What version of KVM have you tried it on and how is it configured > (eg. libvirt xml or qemu command line) I can't say. We use hosted environment with web panel only (elastichosts.com) I will try to start the same machine on different host with "clean" libvirt.
