Xen 3.3.0 cpu cache problems
Dear Xen users, I have a problem with "Xen 3.3.0". All domU (paravirt) only have "32 KB" of cache instead of "6144 KB" as listed in dom0. This is really noticeable under load since the system tends to be really slow. I did not have this problem with "Xen 3.2.1". I''m using the same domU configuration files for the new and the old installation.

desviacion estandard
Hola chic en s, tengo una pregunta teórica. Tengo la evolución de una variable en función del tiempo. Hay 145 valores. Los primeros 1 son 0, y los demás son crecientes. Calculo la desviacion estandard con R, contemplando las 145 muestras (incluyendo los 0), y las 132 muestras (sin incluir los ceros). Me da que la desviación estandard sin contemplar los 0 es mayor. Como puede ser? no le veo el

howto upgrade
Hi, I would like to ask the proper or recommended way of upgrading xen...? I started with 3.1.0 then upgraded to 3.2.1 but now I am not able to use the original system. Since I am not satisfied[*] with the current setup I would try to upgrade to 3.3.1 but it would be nice if something went wrong I could downgrade it to 3.2.x... It is a pitty that booting the previous xen image does not work

RE: xen - rdma live migration support
Hi Ola, There was some code done by IBM a few years ago in conjunction with a University that worked and showed the benefits but AFAIK it was never integrated into Xen. The research paper is around on the web. A few of us requested RDMA migration support for version 4.0 and it is at the top of the request list, I suspect it is probably a case of enough people asking and Citrix approving.

Does anyone know of a general guide for installing PV guests with virsh-install? (Most Centos docs seem to use the GUI based virt-manager and I only have command line access). Am I meant to make use of the files here:

Large server, Xen limitations
Hi, we''re contemplating getting a large new server, where we will run a number of virtual servers. Are there any things we need to keep in mind in that case? Are there limitations on what a Xen system can manage? We''re talking about a 4 x Quad core CPU server with 64 GBs of RAM and a couple of terabytes of RAIDed SATA storage. -Morten (Re-sending this, as the first message

The subject says it all really, I''m pretty sure the system and bios are NUMA aware but I''m not sure if it''s enabled? Is it supported in 3.2.1 stable?
