Hello All, Does anyone know what is the current status of RHEL 5.2 x86_64 with respect to the maximum amount of RAM detected by the Xen 64 bit kernel (the one that shipped with Red Hat distribution ) In the following link https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/en-US/RHEL510/Virtualization_Guide/ch-virt-hw-support.html it states that 32GB of RAM is the maximum amount of

Hello list; I´ve updated my windows 2k3 GPLPV drivers from 0.9.9 to 0.9.12-pre13. But now, i have two xen block devices; (of course, one of them is not working and is marked with the yellow exclamation). How can i fix it, or how can i uninstall the GPLPV drivers in order to make a clean install? Thanks Juan Pablo _______________________________________________ Xen-users mailing list

I have an error in my dmesg system log about hpet not correctly enabling: hpet_acpi_add: no address or irqs in _CRS The same kernel without Xen enables it fine: hpet0: at MMIO 0xfed00000 (virtual 0xffffffffff5fe000), IRQs 2, 8, 31 hpet0: 3 32-bit timers, 25000000 Hz hpet_resources: 0xfed00000 is busy Do I have to pass an additional boot option? (ACPI is already enabled) or is there

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.

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.

Hi Everyone, This is going to sound silly but... I''m just off the phone with a Microsoft SPLA reseller. They sell licenses to run Microsoft software in a hosted environment. I was asking about obtaining Windows licenses to run on my Xen VPS hosting solution. Maybe there is a big misunderstanding, but I''m faily sure she said that it was illegial for me to rent out Xen

i''m reading up on numa usage. so far, i''ve enabled numa on my Xen box. @ Dom0 i see, xm dmesg | grep -i numa (XEN) Command line: ... numa=on ... (XEN) No NUMA configuration found i guess i need to ''configure'' numa. i''ve no clue how, and haven''t found the docs for it yet, despite looking. i found this old thread,

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

I have been using the built in Xen Paravirt NIC drivers for paravirt networking and had bad performance until I disabled all offload setting on the bridge and paravirt nic (From Dom0). There are 2 related questions I have, where should I be tweaking the offload settings, the Dom0 Physical NIC, The Bridge or the DomU NIC? Which settings in particular tend to cause trouble? (I just disabled all of

Sorry to have so many questions but I seem to have quite a few mini problems with my first Xen setup. My xen server works fine with Powernow on the standard Kernel but with the Xen kernel it fails. Does anyone know why? Details below. With Standard Kernel powernow-k8: Found 2 Quad-Core AMD Opteron(tm) Processor 8350 processors (8 cpu cores) (version 2.20.00) powernow-k8: 0 : fid 0x0

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

Hello, I am trying to install Win2008 x64 on xen. However it always crashes with: 0x0000005b which from my research means incompatible CPU. Can anyone assist with this?

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

Hi Everyone, I have a Dell R210 server which has a Xeon X3430 Quad Core CPU (2.4Ghz x 4) with 8GB of RAM. I intend to use the H200 controller in a RAID1 setup How many VMs do you think I''d be able to run on this machine? Is 20 pushing it? I''d say most (if not all) guests would be in PV mode.

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?

Hi experts, Q1:What''s the different for "dom0_max_vcpus=4 dom0_vcpus_pin" and "dom0_max_vcpus=4" ? which will get better performance Q2: dom0_max_vcpus=4 means "core0-3 will be just used by dom0" or means "4 cores(not dedicate cores) will be used by dom0, eg: core2-5 or core3-6? Q3.what does mean "nosmp" , xen, dom0,domU, will just use one

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
