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.

RHEL 5.2 i386 image - Xen kernel doesn''t recognize the total amount of system memory
Hello, We have installed RHEL 5.2 Server ( i386 image ) on a machine with 64GB of RAM. When booting the default PAE kernel ( 2.6.18-92.el5PAE ) that is shipped with RHEL 5.2 installation the OS detects 64GB of RAM. But when booting the Xen kernel ( 2.6.18-92.el5xen ) the OS detects only 14GB of the total amount of available RAM. Did anyone encounter this problem before ? Is it a normal

It is a pitty that booting the previous xen image does not work

NIC Offloading Confusion

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

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.

Virsh-install error
Hi everyone, This is my first attempt at a PV guest install from scratch and I''m a tad confused. Have I answered one of the questions virsh-install asks wrongly? 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:

Linux PV Drivers - VBD device not loading - Cannot get Major 3/22 for ide
I am trying to get PV drivers running on both Centos 5.1 and Centos 5.3 HVMs, my DomU is Centos 5.2 with Xen 3.31. For 5.1 I install the kmod-xenpv RPM but for 5.3 the drivers seem to be built-in. For the network drivers to work I had to unload the Realtek NIC driver and renamed its .ko files to stop it loading. Adding the Xen-Vnif alias to modprobe.conf then got the PV NICs working nicely (Much

Hi Everyone, I''m trying to get Xen to use a native DRBD device but it seems it will not create the virtual machine. It does not seem to like the DRBD device type, any ideas on what might be wrong? I''m pretty sure my xen config file is OK and the DRBD device looks fine too. Full details below. xm create centostest Using config file "./centostest".
